Imaging findings in epithelioid hemangioendothelioma.

Purpose-objective: Epithelioid hemangioendothelioma (EHE) is a rare vascular malignancy with varying biologic behavior. The purpose of this study was to identify imaging findings most characteristic of EHE.

Methods: Retrospective review of clinical and imaging records in patients referred to our Vascular Anomalies Center over a 17 year period with biopsy proven EHE.

Pitfalls in pediatric radiology.

This essay depicts some of the diagnostic errors identified in a large academic pediatric imaging department during a 13-year period. Our aim is to illustrate potential situations in which errors are more likely to occur and more likely to cause harm, and to share our difficult cases so other radiologists might learn without having to experience those situations themselves.

Lower iodine load in routine contrast-enhanced CT: an alternative imaging strategy.

Objective: To demonstrate an alternative imaging strategy for routine thoracic computed tomography using low intravenous contrast volume.

Methods: Based on radiologists' clinical judgment, 61 thoracic computed tomographic examinations were performed using 15 mL of iohexol intravenous contrast. Indications included patients with relative con traindications to contrast, American College of Radiology appropriateness rating of 1 to 6 for contrast, rating of 7 or greater for contrast with a modifying condition, and cases without specific rating in which contrast may have been useful although not mandatory.
