The risks associated with CTCA include radiation exposure, risk of contrast dye reaction and minor allergic reactions from topical anesthesia. However, these risks are minimal when performed by experienced professionals.

Before having a CTCA, you should discuss any medical conditions or allergies with your doctor. You should also let them know about any medications you are taking and if you are pregnant or breastfeeding.

Contrast dye is used so that images produced by the scan appear more clearly on X-ray films and computer monitors and in order for areas of blockage or narrowing in laser photographic images which appear darker than other areas on film.

Yes, radiation is involved during a CT scan but it is kept at very low levels to minimize radiation exposure while producing high quality images of internal structures within human body tissues. The level of radiation exposure required for this exam usually falls below internationally accepted safety limits set by organizations including ACR (American College of Radiology) & FDA (Food & Drug Administration).

Patients undergoing CTCAs must meet certain criteria in order to ensure safety and produce good quality images such as not being pregnant; having no severe kidney damage; having no severe allergies combined with other issues like asthma; never having had certain heart surgeries before; etc…
