Primary osseous tumors of the spine are rare lesions and much less frequently encountered than metastases, multiple myeloma, and lymphoma. The interpreting radiologist must be aware of the typical radiographic appearance of the most common nonmyeloproliferative tumors of the spine because these tumors must be considered when a solitary spinal lesion is(More)
PURPOSE To validate a technique for reproducible measurement of the osteochondroma cartilage cap with computed tomography (CT) and magnetic resonance (MR) imaging and to reevaluate the correlation of the thickness of the cartilage cap with pathologic findings to improve noninvasive differentiation of benign osteochondromas from secondary chondrosarcomas.

OBJECTIVE This study examines interpreter accuracy and interobserver agreement in evaluating conventional radiographs for scaphoid waist fracture displacement. METHODS Six fresh-frozen cadaver arms were obtained transected above the elbow. A waist fracture was created in each scaphoid. In a random fashion, three of the fractures were displaced 1 mm in the(More)
The purpose of this case study was to ascertain the perceptions of health professionals who were located in six rural communities where hospital closure occurred, regarding the impact of closure on community residents. These health professionals were asked to respond to questions about effects of hospital closures on the availability of medical services(More)
Substantial cost, morbidity, and mortality are associated with acute proximal femoral fracture and may be reduced through an optimized diagnostic imaging workup. Radiography represents the primary diagnostic test of choice for the evaluation of acute hip pain. In middle aged and elderly patients with negative radiographs, the evidence indicates MRI to be(More)
These studies describe a high affinity calcium (Ca++)-dependent ATPase in purified testicular plasma membranes, which exhibits increased activity from weaning age to adulthood. Administration of human chorionic gonadotropin (hCG; 5 IU) increased enzyme activity in 21-day old and pubertal (35 to 40-day old), but not in adult mice. In pubertal mice, these(More)
This ACR Appropriateness Criteria article offers imaging triage guidance for several variants of patients presenting with acute foot trauma. Patients meeting inclusion criteria for the Ottawa Rules should undergo a 3-view radiographic series. Diabetic patients with peripheral neuropathy should undergo radiography, even though they do not meet the Ottawa(More)
More than 500,000 visits to the emergency room occur annually in the United States, for acute knee trauma. Many of these are twisting injuries in young patients who can walk and bear weight, and emergent radiographs are not required. Several clinical decision rules have been devised that can considerably reduce the number of radiographs ordered without(More)
Female patients with Hodgkin's disease who undergo staging laparotomy frequently have oophoropexy performed to preserve both fertility and hormone production. Because of recent changes in therapy favoring systemic chemotherapy rather than total nodal irradiation for patients with stage III Hodgkin's disease, the need for oophoropexy may be less than(More)
Thirty-nine cancer patients (Ca) and 37 age-and sex-matched healthy controls (Co) evaluated 11 commercially available enteral supplements using a modified wine-tasting scale. The cancer patients were 19 males with lung cancer and 20 females with breast cancer, and their controls consisted of 17 males and 20 females, respectively. Mean evaluation scores for(More)
