A member asked:

If my total body exposure to radiation is 22 msv, how much more radiation is my heart exposed to in a cardiac ct scan?

5 doctors weighed in across 2 answers

Not sure: I have not seen the radiation dose to the heart specifically separated out. In general cardiac ct will result in around 7-15 msv exposure. The newer generation scanners are using a lower dose of radiation so this value is dropping.

Not sure: You would need a medical physicist to calculate the actual exposure dose.
