A Catheter angiography is a interventional test of the blood vessels. It shows detailed vessel pictures through a catheter; treatment can be done at the same time. Typical effective dose 5 to 15 mSv, similar to about 2 to 5 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.
