Overview
MRI may be helpful in the diagnosis of gallbladder cancer. Findings on MRI diagnostic of gallbladder cancer include
MRI, MRA, and MRCP
- MRI,MRA and MRCP can help in differentiate benign from malignant gallbladder lesions.[1][2]
- .The combination of MRI (magnetic resonance imaging) with MRA (magnetic resonance angiography) and MRCP (magnetic resonance cholangiopancreatography) is paticularly useful in diagnosing the following [3][4]
- Involvement of biliray tarct with a sensitivity100% and specificity of 89%
- Vascular invasion with a sensitivity100% and specificity of 87%
- Involvement of liver with a sensitivity 67% and specificity of 89%
- Involvement of lymphnodes with a sensitivity56% and specificity of 89%
MRI
Dynamic MRI considered being useful and reliable in staging of advanced gallbladder cancer. MRI combined with magnetic resonance cholangiography is sensitive in detection of obstructive jaundice, liver invasion as well as liver and lymph nodes metastasis. It may be more difficult to delineate the invasion to duodenum and omental metastasis by MRI. Reported sensitivity rates for direct hepatic invasion and lymph node invasion on MRI can be as high as 100% and 92% respectively. [5]
