OBJECTIVE We undertook this study to document the MR appearances of evolving or resolving infectious spondylitis. MATERIALS AND METHODS A retrospective review was carried out of all patients with infectious spondylitis who had undergone MR imaging from 1991-1993 at Boston University Hospital and Boston City Hospital Imaging Foundation. The study(More)
The logistics of complying with current American Cancer Society breast cancer screening recommendations in a large health maintenance organization, serving more than 50,000 women age 40 or older, are described. An alternative screening approach estimated to be at least as health-effective as the American Cancer Society recommendations has been developed and(More)
Because of a family history of neurologic problems and the documentation of three vascular lesions in one patient, we evaluated 18 members representing three family generations with magnetic resonance imaging. Of these, eight were normal, two had abnormalities probably not related to arteriovenous malformation, one scan was suboptimal, and the remaining(More)
BACKGROUND MR angiography (MRA) provides a mechanism for non-invasively studying blood flow, thus providing a new opportunity to study the intracranial circulation in asymptomatic sickle cell disease (SCD) patients. Although conventional angiography is the gold standard for the depiction of vascular anatomy, this is too invasive for an asymptomatic(More)
Radionuclide scintigraphy can give a specific diagnosis when a hypervascular "cold" defect on colloid scans "fills in" with gallium scanning. The majority of hepatocellular carcinomas will also accumulate hepatobiliary agents especially in delayed images. Magnetic resonance imaging is superior to other modalities in providing anatomic detail, such as(More)
Radiotracer scintigraphy has been commonly used in this country to confirm and document the clinical diagnosis of brain death. Whether the presence of radiotracer activity in the region of sagittal venous sinus (SVS) represents actual blood flow to the brain in the absence of demonstrable cerebral arterial flow remains a controversial issue. Our(More)
PURPOSE To establish the frequency, distribution, and pathogenesis of cerebral infarction as confirmed with MR imaging in a cohort of patients with acquired immunodeficiency syndrome (AIDS). METHODS We reviewed all (71) abnormal cranial MR studies obtained at our institution in human immunodeficiency virus (HIV)-positive patients over a 2-year period and(More)
