Depends on specifics: Effective radiation dose from thalium stress test is about 17msv. Agents used today achieve much lower doses.Ct abd/pelvis radiation dose depends on many factors -automatic tube current modulation, body habitus & multi vs one phase - on average about 10-15msv.Newer techniques have significantly reduced the dose.To put it in perspective we all receive about 3msv each year from background radiation.

Depends on specifics: But in general, a stress/rest myocardial perfusion exam with thallium would typically be around 18 msv. If you know how much thallium was used (it should be in the report as mci or mbq), a more accurate calculation can be made. An abdominal/pelvis ct has more variables, based on your size, the scanner, how many scans, etc, but a ballpark would be 14 msv. Every year we get 3 msv naturally.
