Helical CT of the Local Spread of Carcinoma of the Gallbladder: Evaluation According to the TNM System in Patients Who Underwent Surgical Resection

Abstract

Helical CT provided 83-86% accuracy in the diagnosis of the local extent of carcinomas of the gallbladder, showing acceptable sensitivity and specificity for the T2 and more advanced lesions but poor sensitivity for the T1 lesions. Use of a monitor with multiplanar reconstructions of the CT data did not significantly improve the diagnostic accuracy.
