Appendiceal CT in 140 cases. Diagnostic criteria for acute and necrotizing appendicitis

Y H Choi et al. Clin Imaging. 1998 Jul-Aug.

Abstract

Computed tomography (CT) was performed in 140 patients with suspected acute appendicitis. Thin collimation (5 mm), intravenous contrast enhancement, 1-second scan times, and supplementary cecal air insufflation were emphasized. CT accuracy was 98% overall (137/140), and 99% in the 124 cases with early surgery. Necrotizing appendicitis was diagnosed by CT with 86% accuracy and 90% positive predictive value.
