Expert opinions? which has more radiation: bone scan or ct?

It's complicated..: Ct scans can be done with different settings but in general, a tc bone scan should have less radiation than a ct scan but it depends on what portion of the body the ct scan is performed on. Ct chest? Abdomen? Pelvis? All of the above?

Sometimes same dose: Background radiation at sea level: 3 msv per year, denver residents get: 6 msv per year, cross country flight: 0.02 msv, x ray chest: 0.06 msv, ct head: 3 msv, ct chest: 5 msv (equivalent to 100 chest xrays) ct abdomen: 5-10, average bone scan 6.5 msv.
