Ultrasound imaging has known limitations and large variations in the sensitivity and specificity of diagnosis of acute cholecystitis. There is limited literature on the sensitivity and specificity of MR imaging, however, the reported are similar to ultrasound, but without the variation. We did a retrospective review of MR imaging in patients with suspected acute cholecystitis. Results showed that MRCP is very insensitive, but has excellent specificity in diagnosis of acute cholecystitis. In conclusion, additional imaging approaches are suggested such as those including functional imaging such as HIDA or MRI with the use of hepatobiliary contrast agents.
