stress thallium is a test which comes under nuclear medicine department
its better termed as stress M1B1 gated scan with spects
its done in two phases
during the first phase you would be asked to walk in a tread mill and at the end of the walk you would be injected by a radioactive dye
images of heart will be taken by radio activity scanner after that you would be ask to come after about 120minutes
as 120minutes is the approx time taken by heart to come fully at rest
again images will be taken after 2hours

both the initial and final images will be compared
if blood supply to a part of heart is normal the radioactive dye injected earlier will be cleared from that part of the heart by flow of blood
but in case blood supply to a part of heart is compromised in that case the remains of radioactive dye will remain at that part as blood is not reaching there so radioactive dye will not be cleared fully
it costs 18000inr in top notch hospitals
thanks!!
