	Functional anatomy of the human temporal muscle - Surgical-Radiologic Anatomy
	Conclusion: Our study showed three distinct anatomical portions in the middle of the temporal muscle which correspond to this functional classification. The MRI study confirmed the results of our anatomical study...
	Radiograph Evaluation in Children With Acute Hip Pain - Journal of Pediatric Orthopaedics
	Conclusion: These results indicate that despite the potential risks of increased radiation exposure with more than one view, combined AP and FL radiographs improve the diagnostic accuracy compared with single views alone. The authors believe that the additional radiation burden is therefore justified...

	A rig for acquisition of standardized trabecular bone radiographs - Acta Radiologica
	Calibration Plexiglas sheets were mounted on ball bearing slides to obtain radiographs without a calibration pattern (suitable for the analysis of trabecular bone texture) and radiographs containing a calibration pattern (suitable for the measurement of leg alignment)...

April 25, 2002   A Comparison of Intertendinous and Classical Approaches to Popliteal Nerve Block Using Magnetic Resonance Imaging Simulation - Anesthesia & Analgesia Conclusion: A simulation of popliteal block using magnetic resonance imaging in volunteers suggests that using tendons of the hamstring muscles as the anatomical landmarks yields a more consistent localization of the sciatic nerve...   Traumatic injuries: role of imaging in the management of the polytrauma victim (conservative expectation) - European Radiology Monitoring of conservatively treated trauma victims by means of repeat CT studies enables early detection of a variety of delayed, clinically silent complications of trauma, e.g., posttraumatic biloma or bowel devascularization. Catheter angiography may be reserved to selected cases with vascular injuries proven on CT...   Validation of the Ottawa knee rules in an emergency teaching centre - European Radiology The Ottawa knee rules remain highly sensitive when applied by medical users with different levels of qualification, such as encountered in a teaching setting...   Imaging of chronic posttraumatic osteomyelitis - European Radiology This review gives an overview of definition, epidemiology, and pathophysiology of chronic posttraumatic osteomyelitis and discusses the value of currently used imaging modalities...   Extraskeletal myxoid chondrosarcoma arising in the finger - Skeletal Radiology We present an unusual case of the tumor arising in the finger. The diagnosis was confirmed by molecular detection of a characteristic EWS-CHN/TEC fusion gene transcript. Molecular detection of the tumor specific fusion gene could be a valuable aid for the final diagnosis of EMCS, particularly in cases with unusual clinicopathological features...   Normal murine bone morphometry: a comparison of magnetic resonance microscopy with micro X-ray and histology - Skeletal Radiology Conclusion: Our results demonstrate that the percent area of marrow increases and percent area of trabecular bone and cortical bone thickness decreases on moving from the epiphyseal growth plate to the diaphysis. These changes observed with MR microscopy correlate with the histological data, but did not correlate with micro X-ray data, which showed no trends. Our quantitative evaluation using MR microscopy was found to be an effective means to visualize the normal variation in bone microanatomy compared with a histological "gold standard", and was a superior means of quantification in comparison with micro X-ray...   The middle glenohumeral ligament: normal anatomy, variants and pathology - Skeletal Radiology The purpose of this pictorial assay is to illustrate the normal anatomy, biomechanics, normal variants and pathology of the middle glenohumeral ligament, as shown on MRI and MR arthrography of the shoulder...

April 19, 2002   Case report: Dysplasia Epiphysealis Hemimelica Of Lateral Aspect Of The Distal Ulnar Epiphysis - Internet Journal of Radiology A 15-year-old female presented to the orthopaedic clinic with a long history of swelling and pain in the left wrist. Clinically there was no limitation of the range of motion of the wrist or shortening of the limb and the right wrist was unaffected without any symptoms...   Usefulness of the skyline view in the assessment of acute knee trauma in children - Canadian Association of Radiologists Journal Conclusion: The skyline view radiograph is useful only if the patient's history suggests subluxation or dislocation of the patella. Otherwise, the skyline view is unlikely to reveal the injury and exposes the patient to unnecessary radiation, discomfort and additional cost to the hospital...   April 17, 2002   Radiologic Screening for Midfacial Fractures: A Single 30-Degree Occipitomental View Is Enough - Journal of Trauma Conclusion: A single 30-degree occipitomental view would be sufficient to screen for maxillofacial trauma. Further views are unnecessary and add little clinical value. Computed tomographic scanning with three-dimensional reconstruction of the facial skeleton should be the next preferred investigation for any patient found to have fractures on the Waters views...

April 11, 2002   ADA petitions FDA for revision to radiograph guidelines - ADA News Conclusion: The American Dental Association has formally contacted the Food and Drug Administration’s Center for Devices and Radiological Health to request new guidelines for dental radiographs. “Comprehensive dental care must include accurate diagnostic care,” says Dr. D. Gregory Chadwick, ADA president. “Dentists rely on radiographs — at their current technological level — to make sound clinical judgments. “The ADA has been aware that current FDA guidelines on radiographs need updating, and this point was unanimously agreed upon in meetings with the Academy of General Dentistry,” he adds. ...   Solitary plasmacytoma of the spine in an adolescent: a case report - Pediatric Radiology Conclusion: Solitary plasmacytoma of bone is a rare disease in patients younger than 30 years, and only a few cases have been reported in children and adolescents. We report the findings of a destructive lesion of the spine due to solitary plasmacytoma in an adolescent patient...   Painful os styloideum in a child - Pediatric Radiology Conclusion: We report a case of a 12-year-old girl who presented with os styloideum. She was evaluated with plain radiographs, bone scintigraphy, and wrist CT. Plain radiographs were initially interpreted as normal. Bone scintigraphy demonstrated focal tracer uptake in the right trapezoid. CT demonstrated an os styloideum fused to the right trapezoid associated with secondary degenerative changes. Os styloideum is a rare cause of wrist pain in children...   Charcot neuroarthropathy of the knee in Type 1 diabetes: treatment with total knee arthroplasty - Diabetic Medicine Result: The case illustrates some of the typical radiological features of this uncommon condition, which may aid early diagnosis and limit morbidity...   Metastatic breast carcinoma mimicking periodontal disease on radiographs - Journal of Clinical Periodontology Conclusion: Radiographic view of a tumor in the present case mimicked a periodontal lesion with an osteolytic area around the roots...   April 10, 2002   Rheumatoid factor is the major predictor of increasing severity of radiographic erosions in rheumatoid arthritis: Results from the Norfolk Arthritis Register Study, a large inception cohort - Arthritis & Rheumatism Conclusion: High-titer RF is an important variable in predicting continuing severity of radiographic damage during the first 5 years after presentation with inflammatory polyarthritis ...   The influence of patient characteristics, disease variables, and HLA alleles on the development of radiographically evident sacroiliitis in juvenile idiopathic arthritis - Arthritis & Rheumatism Conclusion: In the current study, radiographically evident sacroiliitis had developed in 6% of JIA patients after a median disease duration of 14.9 years. HLA-B27, absence of DPB1*02, late onset of disease, and early hip involvement were predictors of sacroiliitis ...   April 05, 2002

April 05, 2002     Musculoskeletal case 21. Presentation - Canadian Journal of Surgery A 59-year-old woman complained of sudden onset of severe disabling back pain.
