10 msv, equal to about 3 years of background radiation During this time, acquisition techniques were rarely adjusted based on body size ( 3 ). For example, in a properly performed ct brain perfusion exam, 10 the radiation output is typically 4 to 10 times of that in a routine head ct exam (200 to 500 mgy vs.

As a ct scan exposes a person to radiation, there is a risk that the person could develop cancer from excessive radiation doses. According to national council on radiation protection and measurements report 160, head, chest, abdomen, and pelvis, or hcap, ct protocols account for nearly 80% of all hospital ct examinations and collectively these examination types accounted for 85% of the total dose received.
