• CT scanning assesses the extent of the tumor within the bile duct and its extension into the adjacent liver,
lymph nodes or other structures within the abdomen. Often, bile duct cancer is not seen on a CT scan.
• Magnetic resonance imaging (MRI) may be helpful in determining if the bile duct cancer can be surgically
removed.
• If the diagnosis of cancer is confirmed or suspected, a chest x-ray should be done to look for tumor nodules in
the lungs that would confirm the distant spread of the cancer.
Endoscopy and Biopsy
• Biopsy, either with a fine needle (FNA) or regular needle, can be done through the skin without significant
danger or through the scope when ERCP is done. The tumor cells may also be found in the bile; they are
characteristic. Their presence may help decide whether surgery should be performed if the other studies also
suggest the tumor has spread. It can be difficult to obtain an adequate biopsy sample because the tumors are
often small and lie within normal liver tissue .
