Acute Knee Dislocation: Review of an Elusive Entity

Publication year: 2009Source: Current Problems in Diagnostic Radiology, Volume 38, Issue 6, November-December 2009, Pages 237-250Sangita, Kapur , Robert D., Wissman , Michael, Robertson , Sadhna, Verma , Michael C., Kreeger , ...The knee consists of three articulations: the patellofemoral, the tibiofemoral, and the proximal tibiofibular joint. Any of these joints can dislocate. Dislocations are uncommon, tend to spontaneously reduce, and can be difficult to detect on clinical examination. There are, however, telltale imaging features and the radiologist may be the first to suggest the correct diagnosis. A timely diagnosis is important as some forms are associated with limb-threatening complications. Lateral patellofemoral dislocation, in the acute setting, is typically an injury of young athletes and usually spontaneously reduces at the time of trauma. In transient lateral dislocation, contusions may be seen in...

Multidetector Computed Tomography Findings of Dense Pulmonary Emboli in Oncologic Patients

Publication year: 2009Source: Current Problems in Diagnostic Radiology, Volume 38, Issue 6, November-December 2009, Pages 251-263Alberto, Villanueva , Maria Lourdes, Díaz , Armando, Sánchez , Eva, Castañer , Gorka, Bastarrika , ...Pulmonary embolism is a frequent condition for which multidetector computed tomography (MDCT) plays an important role in its detection. Occasionally, on MDCT studies, dense linear branching opacities may be found within the pulmonary vessels. They represent dense emboli within the pulmonary arteries (DEPA). These may occur in oncologic patients that undergo specific treatments or interventional procedures, such as cement embolus from vertebroplasty, catheter or coil migration after embolization procedures, radioactive seed embolus in patients treated with local brachytherapy for prostate, lung, or liver cancer, and also in chronic pulmonary embolism. Usually DEPA does not have any clinical significance but may...

Hysterosalpingography: Technique and Applications

Publication year: 2009Source: Current Problems in Diagnostic Radiology, Volume 38, Issue 5, September-October 2009, Pages 199-205Athanasios, Chalazonitis , Ioanna, Tzovara , Fotios, Laspas , Petros, Porfyridis , Nikos, Ptohis , ...Hysterosalpingography (HSG) remains an important radiologic procedure in the investigation of infertility and has become a commonly performed examination due to recent advances of reproductive medicine. HSG demonstrates the morphology of the uterine cavity, the lumina, and the patency of the fallopian tubes. In this review article, we present the technical parameters of the examination, indications, contraindications, and possible complications of HSG. We also illustrate a variety of abnormalities of the uterus and fallopian tubes that can be detected accurately with HSG. We believe that, with the increased demand for HSG, radiologists should be familiar with HSG technique and the...

Non-Electrocardiogram-Gated Multidetector-Row Computed Tomography Findings of Cardiac Pathology in Oncologic Patients

Even without electrocardiogram gating, MDCT provides accurate information about the heart. In the group of oncologic patients, different tumoral and non-tumoral-related heart disorders can be found, for example, metastatic cardiac involvement (approximately 10% of patients with lung or breast cancer will develop metastases to the heart), paraneoplastic cardiac disorders, non-tumor-related heart disorders, and chemotherapy- and radiotherapy-related cardiac side effects. MDCT plays a role in the...

Pediatric Cranial Doppler Sonography in Children: Non-Sickle Cell Applications

Radiological Manifestations of Skeletal Lymphoma

Publication year: 2009Source: Current Problems in Diagnostic Radiology, Volume 38, Issue 5, September-October 2009, Pages 228-236John, O'Neill , Karen, Finlay , Eric, Jurriaans , Lawrence, FriedmanLymphoreticular neoplasms primarily arise in extraskeletal locations with skeletal involvement usually secondary to hematogenous spread or by direct invasion from surrounding involved lymph nodes or soft tissues. Primary lymphoma of bone is relatively rare in comparison. Lymphoma encompasses Hodgkin's and non-Hodgkin's disease, Burkitt's lymphoma, and mycosis fungoides. Skeletal disease may present with symptoms localized to the site of bone involvement, as an incidental finding on imaging for other reasons, or as part of the staging of the disease. It is important that the radiologist is cognizant of the many presentations of skeletal lymphoma. We present a review of the radiological...

Multidetector Computed Tomography of the Acute Abdomen in the Immunocompromised Host: A Pictorial Review

Publication year: 2009Source: Current Problems in Diagnostic Radiology, Volume 38, Issue 4, July-August 2009, Pages 145-155Simon P., Spencer , Niall, Power , Rodney H., ReznekImmunocompromised patients include those receiving chemotherapy for malignant disease, post-transplant patients, patients with acquired immunodeficiency syndrome (AIDS), and those receiving steroids for autoimmune diseases. Advances in transplantation, oncology, and the treatment of AIDS have extended these patients' life expectancies and thereby increased the immunocompromised population. Classical clinical signs of abdominal sepsis may be absent in the immunocompromised host. Consequently, the radiologist is increasingly called on to diagnose specific acute intra-abdominal complications associated with immunodeficiency. This review describes the etiology of the acute abdomen in this heterogeneous group of immunocompromised patients, causes including opportunistic infections, neutropenic enterocolitis, complications of therapy, and...

Positron Emission Tomography/Computed Tomography Potential Pitfalls and Artifacts

Publication year: 2009Source: Current Problems in Diagnostic Radiology, Volume 38, Issue 4, July-August 2009, Pages 156-169Xia, Wang , Spencer, KochWith the recent use of 18-fluoro-2-deoxyglucose (FDG) positron emission tomography (PET) for tumor staging and treatment response, it is important to recognize many pitfalls, artifacts, and benign uptakes that are commonly encountered. Normal physiology can explain many regions of increased FDG activity, as well as incidental benign tumors and benign metabolic conditions. Recognition of characterization of benign causes and physiologic variants for FDG uptake are discussed to avoid improper characterization as a malignancy. A basic understanding of PET/computed tomographic physics is also discussed, in relation to attenuation correction artifacts caused by metallic implants and contrast agents in the gastrointestinal tract,...

Chest ports play an important role in the management of oncology patients who need frequent blood products, chemotherapy, and other intravenous drugs. Imaging-guided placement of chest ports and catheters (CR) is a safe and efficacious procedure. Moreover, many cases of catheter-induced central thrombosis go unrecognized, but the incidence of pulmonary embolism in this group may be as high as 12%. Multi-detector computed tomography represents the main imaging method in the follow-up of oncologic patients. We review the radiologic features, mainly on multi-detector computed tomography, of CR commonly used for...

Doppler ultrasound has an advantage over computed tomography or other imaging modalities in that it is noninvasive, can be used intraoperatively or immediately postoperatively at the patient's bedside, and is free from radiation hazard. Doppler ultrasound is also sensitive to very slow flow and is not limited by an optimal temporal window because it is a real-time examination. However, this examination is highly operator-dependent. For a proper evaluation of patient hemodynamic status, optimization of Doppler parameters and liberal use of spectral analysis will help...

Microwave Ablation Technology: What Every User Should Know

Publication year: 2009Source: Current Problems in Diagnostic Radiology, Volume 38, Issue 2, March-April 2009, Pages 61-67Christopher L., BraceMicrowave ablation is a relatively new technology under development and testing to treat the same types of cancer that can be treated with radiofrequency ablation. Microwave energy has several possible benefits over radiofrequency energy for tumor ablation but, because clinical microwave ablation systems are not widespread, the underlying principles and technologies may not be as familiar. The basic microwave ablation system contains many of the same components as a radiofrequency ablation system: a generator, a power distribution system, and an interstitial applicator. This article attempts to provide an overview of each of these components, outline their functions and roles, and...

Pharyngeal Dysphagia: What the Radiologist Needs to Know

Publication year: 2009Source: Current Problems in Diagnostic Radiology, Volume 38, Issue 1, January-February 2009, Pages 17-32Patrick D., Grant , Desiree E., Morgan , Francis J., Scholz , Cheri L., CanonDysphagia is defined as difficulty in swallowing. Oropharyngeal dysphagia is defined as difficulty in moving the bolus from the mouth to the esophagus. The best initial evaluation of suspected oropharyngeal dysphagia is a barium study which can evaluate motility of the oropharynx and hypopharynx and provide double-contrast views that may identify structural or mucosal abnormalities. Pharyngeal diverticula, Zenker's and Killian–Jamieson diverticula, and pharyngeal pouches are readily identified on these studies. Zenker's diverticula are the commonest diverticulum implicated in pharyngeal dysphagia and typically occur in the setting of cricopharyngeal dysfunction. The radiologist must not only diagnose these diverticula but also understand...

Radiofrequency Ablation of Lung Lesions: Practical Applications and Tips

Publication year: 2009Source: Current Problems in Diagnostic Radiology, Volume 38, Issue 1, January-February 2009, Pages 44-52A. Molly, Roy , Clare, Bent , Tim, FotheringhamRadiofrequency ablation (RFA) therapy is a minimally invasive technique that can be used in the management of inoperable non-small-cell lung cancer and for palliation in selected patients with pulmonary metastases. Surgical resection remains the gold standard of treatment; however, many patients are ineligible due to comorbidities or poor cardiopulmonary reserve. Others may simply decline radical surgical intervention. Alternative treatment options are limited mainly to chemotherapy and external beam radiation. With the development of RFA, a new promising technique has evolved that can be offered to many, as an alternative choice or as part of combination therapy. The published results of...

Although CT enterography is performed with oral hyperhydration, CT enteroclysis requires the placement of an enteroclysis tube, often in patients who are unable to orally consume the amount of liquid. When tolerated, CT enterography is often preferred due to its lack of invasiveness. Magnetic resonance enterography and enteroclysis are other modalities that are still being studied and show promise in the imaging of small...

Publication year: 2008Source: Current Problems in Diagnostic Radiology, Volume 37, Issue 5, September-October 2008, Pages 231-241Joseph, Sutcliffe , Justin Q., Ly , Amy, Kirby , Douglas P., BeallInjuries related to participation in golf are becoming more common given the increasing popularity of the sport itself. Golf is considered to be an activity associated with a moderate risk for sports injuries. Golf injuries are usually attributable to overuse or traumatic mechanisms and primarily occur at the elbow, wrist, shoulder, and lumbar spine. None of these injuries are unique to golf, but each of these injuries represent the most common injuries associated with golfing. This article reviews a wide range of injuries that are encountered in golfers and describes the magnetic resonance imaging findings of each of these injuries.

Getting to the heel of the problem: plantar fascia lesions.

Related Articles Getting to the heel of the problem: plantar fascia lesions. Clin Radiol. 2009 Sep;64(9):931-9 Authors: Jeswani T, Morlese J, McNally EG Heel pain is a frequent disabling symptom. Clinical diagnosis is often difficult with a large range of possible diagnoses. Lesions of the plantar fascia form an important group. We present a review describing the common lesions of the plantar fascia, including plantar fasciitis, plantar fascia rupture, plantar fibromatosis, and plantar xanthoma, and illustrate them with appropriate magnetic resonance imaging (MRI) and ultrasound imaging. We also address foreign-body reactions, enthesopathy, and diabetic fascial disease. PMID: 19664484 [PubMed - indexed for MEDLINE]

CT appearances of pleural tumours.

Related Articles CT appearances of pleural tumours. Clin Radiol. 2009 Sep;64(9):918-30 Authors: Salahudeen HM, Hoey ET, Robertson RJ, Darby MJ Computed tomography (CT) is the imaging technique of choice for characterizing pleural masses with respect to their location, composition, and extent. CT also provides important information regarding invasion of the chest wall and surrounding structures. A spectrum of tumours can affect the pleura of which metastatic adenocarcinoma is the commonest cause of malignant pleural disease, while malignant mesothelioma is the most common primary pleural tumour. Certain CT features help differentiate benign from malignant processes. This pictorial review highlights the salient CT appearances of a range of tumours that may affect the pleura.

Contribution of the amount of contrast media used in pulmonary CT angiography to assess the diagnostic value of CT venography; comparison of 100 and 150ml of contrast media.

Related Articles Contribution of the amount of contrast media used in pulmonary CT angiography to assess the diagnostic value of CT venography; comparison of 100 and 150ml of contrast media. Clin Radiol. 2009 Sep;64(9):912-7 Authors: Calisir C, Yavas US, Kebapci M, Korkmaz A, Ozkan R AIM: To prospectively compare the vascular attenuation achieved with 100ml iohexol (350mgI/ml) 75% with that achieved with 150ml iohexol (350mgI/ml) 75% for computed tomography (CT) venography, which was performed after CT pulmonary angiography. MATERIALS AND METHODS: A total of 122 patients were included in the study. Group A, comprising 52 patients (mean age 64.8 years, mean body weight 70.8kg) received 150ml iohexol (350mgI/ml) contrast media. Group B, comprising 70 patients (mean age 61.2 years, mean body weight 71.4kg) received 100ml iohexol (350mgI/ml) contrast medium. RESULTS: Venous opacification values measured at all levels were significantly higher in group A than those in group B (p<0.001). In group B the mean HU values were between 87 and 115 and only three of the patients had HU values less than 60 at the level of femoral vein. Assuming a venous enhancement of 80HU as the cut-off value for accurate diagnosis of deep venous thrombosis, 22.8% (16/70) in group B and 7.6% (4/52; p=0.028) in group A had non-diagnostic CT venography of left femoral vein. CONCLUSION: One hundred millilitres of contrast medium with a concentration of 350mgI/ml may produce sufficient enhancement, but 150ml of contrast medium provides better accuracy for the diagnosis of deep venous thrombosis diagnosis. For better enhancement of lower extremity deep veins, the concentration of the contrast medium and the patient's body weight may also have significance. PMID: 19664482 [PubMed - indexed for MEDLINE]

Related Articles Are pancreatic calcifications specific for the diagnosis of chronic pancreatitis? A multidetector-row CT analysis. Clin Radiol. 2009 Sep;64(9):903-11 Authors: Campisi A, Brancatelli G, Vullierme MP, Levy P, Ruzniewski P, Vilgrain V AIM: To retrospectively establish the most frequently encountered diagnoses in patients with pancreatic calcifications and to investigate whether the association of certain findings could be helpful for diagnosis. MATERIALS AND METHODS: One hundred and three patients were included in the study. The location and distribution of calcifications; presence, nature, and enhancement pattern of pancreatic lesions; pancreatic atrophy and ductal dilatation were recorded. Differences between patients with chronic pancreatitis and patients with other entities were compared by using Fisher's exact test. RESULTS: Patients had chronic pancreatitis (n=70), neuroendocrine tumours (n=14), intraductal papillary mucinous neoplasm (n=11), pancreatic adenocarcinoma (n=4), serous cystadenoma (n=4). Four CT findings had a specificity of over 60% for the diagnosis of chronic pancreatitis: parenchymal calcifications, intraductal calcifications, parenchymal atrophy, and cystic lesions. When at least two of these four criteria were used in combination, 54 of 70 (77%) patients with chronic pancreatitis could be identified, but only 17 of 33 (51%) patients with other diseases. When at least three of these four criteria were present, a specificity of 79% for the diagnosis of chronic pancreatitis was achieved. CONCLUSION: Certain findings are noted more often in chronic pancreatitis than in other pancreatic diseases. The presence of a combination of CT findings can suggest chronic pancreatitis and be helpful in diagnosis. PMID: 19664481 [PubMed - indexed for MEDLINE]

Radiological impact of the use of calcium hydroxylapatite dermal fillers.

Related Articles Radiological impact of the use of calcium hydroxylapatite dermal fillers. Clin Radiol. 2009 Sep;64(9):897-902 Authors: Feeney JN, Fox JJ, Akhurst T AIM: To report a case series in which the radiological features of the subcutaneous use of calcium hydroxylapatite (CaHa) dermal fillers are described for the first time. MATERIALS AND METHODS: Five patients with facial hyperattenuating hypermetabolic subcutaneous lesions were identified on 2- [(18)F]-fluoro-2-deoxy-D-glucose (FDG) positron-emission tomography/computed tomography (PET/CT), who gave a history of facial injections to augment physical appearance. Correlation with additional imaging studies was performed. RESULTS: All cases had subcutaneous high attenuation material on CT (range 280-700HU), which was FDG avid on PET, with a standardized uptake value (SUV) range of 2.9-13.4. Magnetic resonance imaging (MRI) demonstrated a heterogeneous intermediate signal intensity subcutaneous lesion with enhancement post-gadolinium in one case. CONCLUSIONS: CaHa dermal filler is hyperattenuating on CT, hypermetabolic on FDG-PET imaging, of intermediate signal intensity on MRI, and is a potential cause of a false-positive imaging study.

Discrepancy in reporting among specialist registrars and the role of a paediatric neuroradiologist in reporting paediatric CT head examinations.

Related Articles Discrepancy in reporting among specialist registrars and the role of a paediatric neuroradiologist in reporting paediatric CT head examinations. Clin Radiol. 2009 Sep;64(9):891-6 Authors: Nagaraja S, Ullah Q, Lee KJ, Bickle I, Hon LQ, Griffiths PD, Raghavan A, Flynn P, Connolly DJ AIM: To evaluate the discrepancy rate among specialist registrars (SPR) to assess whether seniority had a bearing on the discrepancy rate. To investigate which were the commonly missed abnormalities and the consequences for teaching purposes. To investigate the role of a specialist consultant neuroradiologist in reporting paediatric head computed tomography examinations. MATERIALS AND METHODS: The study was carried out over a 9-month period at the regional paediatric hospital during which time 270 CT head examinations were reported. Reporting in the department is carried out by one of the five general paediatric radiologists (GR) and also a specialist paediatric neuroradiologist (NR). The NR was considered the reference standard, who corroborated in areas of discrepancy with a second senior NR for this study. Of the 270 examinations, 260 were reported by the paediatric NR, 160 were reported by the SPR, GR, and NR, and 51 were reported by an SPR and the NR. In addition, four were reported by the GR and the NR, 45 by the NR only, seven by the GR only, and three cases were reported by the GR and an SPR. The discrepancy rates were calculated for GR versus NR, and SPR versus NR. All the discrepancies were re-evaluated by a second senior NR and confirmed in all cases. The reports of the SPR were further scrutinized. The trainees of training years 1-3 were considered junior and 4-5 were considered senior. RESULTS: There was a discrepancy in 26/164 cases (15.9%) reported by the GR and NR. There was a discrepancy in 59/211 cases (28%) reported by an SPR and NR. The chi-squared test (two-sided) showed a significant difference (p=0.005) between the two groups. There was a discrepancy in 36/118 cases (30.5%) reported by the junior SPR and NR. There was a discrepancy in 23/93 cases (24.7%) reported by a senior SPR and NR. The chi-squared test (two-sided) showed a non-significant difference (p=0.353) between the two groups. CONCLUSION: The performance of the SPR was considered to be significantly different than the GR in this study. The year of training did not have a statistically significant bearing on the discrepancy rates. This study has been useful in guiding SPR with regards to paediatric CT head examination reporting. The NR played an important role, particularly in picking up subtle fractures and congenital abnormalities, which were missed by both the SPR and GR. PMID: 19664479 [PubMed - indexed for MEDLINE]

CT staging of loco-regional breast cancer recurrence. A worthwhile practice?

Related Articles CT staging of loco-regional breast cancer recurrence. A worthwhile practice? Clin Radiol. 2009 Sep;64(9):885-90 Authors: Tennant S, Evans A, Macmillan D, Lee A, Cornford E, James J, Ellis I AIMS: To assess the usefulness of computed tomography of the chest, abdomen, and pelvis (CTCAP) in the detection of metastatic disease in patients presenting with loco-regional recurrence of breast cancer, and to identify subgroups particularly likely to have metastases. MATERIALS AND METHODS: Over a 32-month period, 63 patients with 65 recurrences underwent CTCAP, and were identified from the hospital's computerized radiology system. RESULTS: Twenty-one patients (32%) had metastases, including bony (n=5, 8%), liver (n=7, 11%), and thoracic disease (n=11, 17%). Patients with recurrence in a conserved breast had lower rates of metastasis on CT than those with other sites of recurrence [three of 21 (14%) versus 18 of 44 (41%), p=0.03]. Patients younger than 50 years at primary diagnosis or younger than 60 years at recurrence had statistically significantly higher rates of metastasis than older patients [10 of 16 (63%) versus 11 of 48 (23%), p=0.003, and 13 of 23 (57%) versus eight of 42 (19%), p=0.002, respectively]. CONCLUSION: CT staging of patients presenting with loco-regional recurrence of breast cancer is a worthwhile practice. Younger patients and those with recurrence other than in the conserved breast are particularly likely to have metastatic disease. PMID: 19664478 [PubMed - indexed for MEDLINE]

Incidentally detected small pulmonary nodules on CT.

Related Articles Incidentally detected small pulmonary nodules on CT. Clin Radiol. 2009 Sep;64(9):872-84 Authors: Edey AJ, Hansell DM The widespread use of multidetector computed tomography for imaging of the chest has lead to a significant increase in the number of incidentally detected pulmonary nodules. The significance of these nodules is often uncertain and further investigations may be required. This article will review the spectrum of imaging appearances of small pulmonary nodules, and highlight the few features that allow confident characterization of a nodule as benign or malignant; current guidelines for the management of incidentally detected nodules will also be discussed.

Cancer presenting during pregnancy: radiological perspectives.

Related Articles Cancer presenting during pregnancy: radiological perspectives. Clin Radiol. 2009 Sep;64(9):857-71 Authors: Doyle S, Messiou C, Rutherford JM, Dineen RA Malignancy presenting during pregnancy is rare. When it does, there are important considerations and challenges for the radiologist. The physiological changes of pregnancy may mask signs and symptoms of malignancy leading to delayed presentation. Endocrine and physiological changes during pregnancy can interact with tumour biology to alter the behaviour and patterns of growth of certain tumours. The timing and choice of imaging technique pose potential risks to the foetus, but this must be weighed against the risks to both mother and foetus of inadequate investigation or misdiagnosis. This review outlines the general principles and approach to imaging the pregnant patient with suspected malignancy, following which there is a more detailed discussion of the effects of pregnancy on tumour biology and presentation of specific tumours. Imaging strategies are discussed for the different entities, and where possible, evidence-based imaging recommendations are made. PMID: 19664476 [PubMed - indexed for MEDLINE]
