Overview
CT scans may be helpful in location, with high sensitivity, the site of obstruction for cholangitis.
CT
- Computed tomography (CT) without contrast injections are more sensitive than ultrasounds in demonstrating choledocholithiasis, a predominant cause of acute cholangitis.[1]
- CT scans have a higher sensitivity (63%) and are accurate in locating the site of obstruction.[2]
- The accuracy of conventional CT scans in determining the presence and level of obstruction is between 81% and 94%.[2]
- Findings on CT scan suggestive of/diagnostic of acute cholangitis include:
- In arterial-phase, there is non-homogeneous liver enhancement
