WebA chest X-ray, by comparison, emits 0.02 mSv of radiation. CT and PET scans emit more radiation and tend to last at least a few seconds. An abdominal CT scan exposes you to between 8 and 10 mSv of radiation, while a coronary CT angiogram exposes you to 16 mSv. And a PET scan, used to detect cancer, issues roughly 25 mSv of radiation. WebComputed tomography (CT) and interventional procedures such as angiography and cardiac catheterisation are associated with higher doses of radiation, about 100 to 1000 times …
