PURPOSE To (a) determine the performance of screening mammography, ultrasonography (US), and physical examination (PE); (b) analyze the influence of age, hormonal status, and breast density; (c) compare the size and stage of tumors detected with each modality; and (d) determine which modality or combination of modalities optimize cancer detection.

The risks to patients with metal surgical implants who are undergoing nuclear magnetic resonance (NMR) imaging and the artifacts caused by such implants were studied. Twenty-one aneurysm and other hemostatic clips and a variety of other materials (e.g., dental amalgam, 14 karat gold) were used. Longitudinal forces and torques were found to be exerted upon(More)
PURPOSE To evaluate bilateral screening ultrasound (US) in the detection of otherwise occult masses and cancer in women with dense breasts and normal mammographic and physical examination findings. MATERIALS AND METHODS Of 11,220 consecutive patients prospectively examined, all 3,626 women with dense breasts and normal mammographic and physical(More)
OBJECTIVE Most studies of contrast-induced nephropathy lack controls to distinguish it from nephropathy from other causes. We assessed the frequency and magnitude of serum creatinine changes in patients not receiving iodinated contrast material to compare with creatinine changes in publications regarding contrast nephropathy. MATERIALS AND METHODS From(More)
PURPOSE To assess the risk of nephropathy after administration of contrast material by reviewing the published literature on intravenous contrast material administration and by separating reports with appropriate control measures from those without such measures. MATERIALS AND METHODS The MEDLINE database was searched for articles published from October(More)
Excised urinary calculi were subjected to computed tomographic (CT) scanning in an attempt to determine whether CT attenuation values would allow accurate analysis of stone composition. The mean, maximum, and modal pixel densities of the calculi were recorded and compared; the resulting values reflected considerable heterogeneity in stone density. Although(More)
PURPOSE To correlate the radiologic and pathologic findings and differential diagnosis of large, degenerated adrenal adenomas. MATERIALS AND METHODS The authors reviewed the radiologic and pathologic characteristics of 30 large adenomas with cystic regions or areas of heterogeneity that were either intrinsic or demonstrated at contrast material-enhanced(More)
PURPOSE We evaluated the independent response rate of dexamethasone before docetaxel and estramustine administration as measured by changes in serum prostate specific antigen (PSA) in patients with androgen independent prostate cancer. MATERIALS AND METHODS A total of 12 patients received 20 mg. dexamethasone orally every 6 hours for 3 doses repeated(More)
