The traditional way of angiography is accomplished by snaking a catheter through a patient’s blood vessels, where a dye is injected near the heart. Patients receiving this test will receive the same amount of radiation, which is found in other standard test such as nuclear stress test.
When patients undergo CT scans they receive radiation equivalent 600 chest X-rays.
The amount of radiation that that is given to a patient depends on where your health care provider sends you to have the CT scan. Some medical facilities take into consideration the size of the patient, when deciding on the dosage. The smaller the patient, the smaller the dosage. The technician may also pinpoint the radiation to the specific portion of the heart, which shortens the patient’s exposure.
