Overview
CT Scan
- Computed tomography (CT) without contrast injections are more sensitive than ultrasounds in demonstrating choledocholithiasis, the leading cause of acute cholangitis.[1]
- CT scans have a higher sensitivity (63%) and are accurate in localizing the site of obstruction.[2]
- The accuracy of conventional CT in determining the presence and level of obstruction is between 81–94%.[2]
