Is it important to take msct scan or sestamibi test after taking catheterization? Is there anything these 2 tests can show that catheterization cant?

Sometimes. Cath reveals the size of the arteries to the heart. Nuclear tests can demonstrate whether the heart muscle is receiving adequate blood supply. This may help in determining whether a partial blockage is causing a problem. Thus the data from the 2 tests can be complimentary and give a more complete picture of the clinical situation.
