A CT coronary angiography (CTCA) is a ct test of the heart arteries. It shows narrowing in the heart arteries. Typical effective dose 2 to 12 mSv, similar to about 8 months to 4 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.
Narrowing in the heart arteries.
Chest pain evaluation in selected patients.
Remove metal objects. If contrast is used you may need to fast for a few hours; tell staff about allergies, kidney disease, diabetes medicines (metformin) or pregnancy.
Typical effective dose 2 to 12 mSv, similar to about 8 months to 4 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.
10 to 20 minutes. General information, not a diagnosis. Results must be interpreted by a qualified health worker.
