Diagnosis of Cholangiocarcinoma

1. Abdominal B-ultrasound: This examination is non-invasive, convenient, low-cost, and repeatable, and is the preferred method for diagnosing bile duct cancer.

2. Abdominal CT: Abdominal CT is better than B-ultrasound in diagnosing hilar cholangiocarcinoma. It can show the location, size, local spread, vascular invasion, degree of bile duct dilatation and ascites of the bile duct mass.

3. Magnetic Cholangiography (MRCP): This examination is a three-dimensional imaging test that can show the entire bile duct and is more intuitive in determining the location, size, and shape of the tumor.

4. Transcutaneous cholangiography (PTC): PTC examination can dynamically observe the flow and distribution of contrast agent in the bile duct, determine whether there is obstruction in the lower opening of the common bile duct, and is more accurate than CT in diagnosing partial or complete obstruction. It is of great value in distinguishing bile duct obstruction caused by tumors, stones or inflammation.
