Formative evaluation of standardized training for CT colonographic image interpretation by novice readers.

Purpose: To introduce an educational intervention-specifically, a specialized training course-and perform a formative evaluation of the effect of the intervention on novice reader interpretation of computed tomography (CT) colonographic data.

Materials And Methods: The study was institutional review board approved. Ten normal and 50 abnormal cases, those of 60 patients with 93 polyps-61 polyps 6-9 mm in diameter and 32 polyps 10 mm or larger-were selected from a previously published trial.

Multidetector row CT of small bowel obstruction.

State-of-the-art multidetector row CT (MDCT) technology has revolutionized abdominal imaging. The ability of CT to determine if bowel obstruction is present, to localize the obstructive site, to determine degree of obstruction, to diagnose the presence of closed-loop obstruction, and to identify ischemia or perforation of the involved bowel is well established. This article illustrates the usefulness of MDCT in the evaluation of small bowel obstruction and related conditions in adults and emphasizes the benefits of advanced CT applications.
