A Percutaneous transhepatic biliary drainage (PTBD) is a interventional test of the bile ducts. It shows a tube to drain blocked bile ducts. Typical effective dose 5 to 10 mSv, similar to about 2 to 3 years of natural background radiation (about 3 mSv a year).
General health information, not a diagnosis. In an emergency, call 102. Always consult a qualified health professional.

Blood tests for clotting are usually needed; blood thinners may need to be paused only on your doctor's advice. Fasting for a few hours is common.
Typical effective dose 5 to 10 mSv, similar to about 2 to 3 years of natural background radiation (about 3 mSv a year). Tell staff if you are or might be pregnant; the benefit usually outweighs the small risk, and shielding or alternatives can be considered.
