Incidence of Severe Adverse Drug Reactions to Ultrasound Enhancement Agents in a Contemporary Echocardiography Practice.

Objectives: Prior data indicate a very rare risk of serious adverse drug reaction (ADR) to ultrasound enhancement agents (UEAs). We sought to evaluate the frequency of ADR to UEA administration in contemporary practice.

Methods: We retrospectively reviewed 4 US health systems to characterize the frequency and severity of ADR to UEA.

Anomalous coronary arteries in adults: depiction at multi-detector row CT angiography.

Purpose: To retrospectively determine the imaging features of anomalous coronary arteries depicted at multi-detector row computed tomographic (CT) angiography in 18 patients seen at four institutions.

Materials And Methods: Eighteen patients underwent imaging with a four- or 16-section multi-detector row CT unit by using retrospective electrocardiographic (ECG) gating after infusion of 120-150 mL of intravenous contrast material. Section thicknesses of 0.
