THALLIUM IMAGING is a very simple procedure. It is done in a resting state or after stress. The purpose of this is to know the extent of MI, also to evaluate the patency of the graft after surgery. It needs consent, and check for allergies.
The Thallium is injected to the body. 10 minutes later take a look at the heart under fluoroscopy for the areas. The thallium should be taken up by all the blood vessels. The areas of thallium which is not taken up appear a white spot and that is the area of infarcts.
CABG- Coronary Artery Bypass Graft. What we do is bypassing the occlusion of the coronary artery so they’ll do a thallium test after wards to make sure that the area that previously showed as a white spot no longer shows as a white spot.
