Overview
On MRI, cholangiocarcinoma is characterized by either isointense or hypointense relative to the normal liver on T1 and mildly to markedly hyperintense on T2. Moderate to incomplete enhancement is obseved on contrast MRI.
MRI
- Abdominal MRI may be helpful in the diagnosis of cholangiocarcinoma. Findings on MRI suggestive of cholangiocarcinoma include:[1][2]
- Isointense or hypointense relative to the normal liver on T1w MR images
- Mildly to markedly hyperintense on T2w images
