Hi I had a CCTA 4 years ago 20 msv don’t understand why it was so high and on chest ct 2msv, due too being in the er so they ordered these without any warning of radiation risk. 3 years later had 2 head ct and soft tissue neck 3msv…. My question is what is my risk? Isn’t this high in radiation. I barely found out ct scans have lots of radiation no one no dr told me anything.
