"T" tube cholangiography is a commonly used X-ray examination method for examining the biliary tract after surgery. This method of examination is simple and safe to operate, and the contrast effect is excellent. This method can be applied to patients who have a "T" tube drainage. An iodine allergy test should be performed before the test, and the test can be checked for negative. The examination is usually performed in the radiology department. The patient should be supine. In the case of strict disinfection, the contrast agent is slowly injected into the biliary tract through the "T" tube. Under the X-ray screen, you can see the filling of the biliary tract, whether there is any lesion, and whether the contrast agent enters the duodenum, etc. If the angiography is satisfactory, you can make a film.

Basic Information

Specialist classification: growth and development check classification: X-ray

Applicable gender: whether men and women apply fasting: fasting

The gallbladder is often densely shaped with eggplant or pear shape, 7-10 cm long and 3-4 cm wide, located below the lower right margin of the right upper abdomen. Various direct biliary angiography results are better, except for the common bile duct and the total hepatic duct, and the left and right hepatic ducts and some branches of the liver are visible. When the normal bile duct is filled, the contour is smooth, the thickness is uniform, and the density is uniform.
