A blinded retrospective study was performed to determine the sensitivity and specificity of computed tomography (CT) in detecting perigraft infection (PGI) and aortoenteric fistula (AEF), rare but devastating complications of aortic reconstructive surgery. Two observers independently reviewed CT scans in 55 cases including AEF (n = 23); PGI (n = 12); and(More)
OBJECTIVE The objective of this article is to provide a practical illustrated review of PET/CT in the imaging evaluation of transitional cell carcinoma. CONCLUSION Local evaluation of the primary tumor in patients with transitional cell carcinoma on PET is often limited by the obscuring effect of excreted FDG, but assessment of metabolic activity may(More)
Medical audit results from the entire experience of a rapid-throughput mammography screening practice are presented, comprising 27,114 examinations conducted from April 1985 to September 1989. The authors screened a self-selected physician-referred population, almost 94% of whom were asymptomatic. Estimated sensitivity of initial mammography interpretation(More)
This retrospective study was performed to assess the potential of magnetic resonance (MR) imaging for demonstrating various types of lipomatous tumors and tumors with fatty component and to compare the results of MR with those of computed tomography (CT). MR examinations of 17 patients with 18 lipomatous tumors (16, benign; two, liposarcoma) and two(More)
PURPOSE To compare mammographic screening results for women aged 65 years and older (elderly group) with those for women aged 50-64 years (younger group). MATERIALS AND METHODS Mammography was performed in 32,140 women aged 50 years and older (10,914 elderly, 21,226 younger). Parameters studied included demographic data, screening interpretations,(More)
To offer mammographic screening to asymptomatic women at low cost requires a different approach than is appropriate for solving the more complex problems presented by symptomatic patients. Since the goal of screening is to detect unsuspected abnormalities, not to characterize them fully, operational procedures can be streamlined to maximize patient(More)
Fifteen patients with suspected or known aortic dissection were imaged with magnetic resonance (MR). Thirteen of these patients were eventually shown to have dissection. In most instances the diagnosis was established by aortography and/or computed tomography (CT) prior to the MR study. Surgical proof (6/13) and/or aortographic proof (10/13) were available(More)
OBJECTIVE The goal of this study was to compare findings on initial and subsequent screening mammograms to determine the prognostic significance of screening-detected abnormalities. MATERIALS AND METHODS All 3386 abnormal examinations from a 9-year mammographic screening program were studied. An initial examination was defined as one for which there were(More)
Thirty-three patients suspected of having bronchogenic carcinoma were studied prospectively using magnetic resonance (MR). In this group, 30 underwent examination with computed tomography (CT), 15 underwent thoracotomy, six had mediastinal biopsy procedures performed, and eight underwent bronchoscopy. MR studies, which included transaxial spin-echo imaging(More)
