PURPOSE To determine retrospectively the frequency, management, and outcomes of extravasations of intravenously injected nonionic iodinated contrast medium. MATERIALS AND METHODS Institutional review board approval was obtained, and the requirement for informed consent was waived. The study was HIPAA compliant. For 69,657 intravenous injections of(More)
OBJECTIVE The study objective was to assess the correlation between (18)F-FDG uptake values on positron emission mammography (PEM), expressed as maximum uptake value and lesion-to-background ratio, and receptor status (i.e., estrogen receptor [ER], progesterone receptor [PR], and human epidermal growth factor receptor 2 [HER2]), tumor histology, and tumor(More)
OBJECTIVE The objective of our study was to evaluate the frequency, outcome, and appropriateness of treatment of adults with acute allergiclike reactions related to IV-administered nonionic iodinated contrast media. MATERIALS AND METHODS For IV injections of nonionic iodinated contrast media between January 1, 1999, and December 31, 2005, contrast(More)
OBJECTIVE The purpose of this study was to compare triplanar 2D T2-weighted turbo spin-echo MR images with reformatted images from a 3D T2-weighted turbo spin-echo sequence in analogous planes with respect to acquisition time, image quality, artifacts, and lesion detection. MATERIALS AND METHODS Forty-four consecutively enrolled women referred for pelvic(More)
The objectives of this article are to review allergy-type reactions to iodinated contrast media and the protocols utilized to prevent or reduce the occurrence of these adverse reactions in high-risk patients. We will begin by discussing the types or classifications of the adverse reactions to iodinated contrast media. We will then discuss reaction(More)
OBJECTIVE The objective of our study was to assess whether high-fidelity simulation-based training is more effective than traditional didactic lecture to train radiology residents in the management of contrast reactions. SUBJECTS AND METHODS This was a prospective study of 44 radiology residents randomized into a simulation group versus a lecture group.(More)
Optimal treatment of thyroid cancer is highly dependent on accurate staging of the extent of disease at presentation. Preoperative ultrasonography (US) is the most sensitive method for detecting metastatic lymph nodes and is recommended as part of the standard preoperative workup. Missed findings on preoperative scans may lead to understaging and inadequate(More)
The proximal ureter (upper) extends from the ureteropelvic junction to where the ureter crosses the sacroiliac joint, the middle ureter courses over the bony pelvis and iliac vessels, and the distal or pelvic (lower) ureter extends from the iliac vessels to the bladder. Benign and malignant lesions can affect the ureter and these may be caused by contiguous(More)
Question: A 29-year-old pregnant woman (17 weeks gestation) presented with severe hypoglycemia (29 mg/dL), a hemoglobin A1C of 4.8%, and mild elevation of liver function tests (LFTs; aspartate aminotransferase [AST], 55 U/L; alanine aminotransferase [ALT], 37 U/L; alkaline phosphatase, 92 U/L). Abdominal ultrasonography revealed innumerable hypoechoic(More)
PURPOSE To retrospectively determine whether extrinsic warming of the low-osmolality contrast material iopamidol to 37°C prior to intravenous administration at computed tomography (CT) affects extravasation and allergic-like reaction rates. MATERIALS AND METHODS The need to obtain informed patient consent was waived for this HIPAA-compliant and(More)
