Anterior and inferior wall infarct on 99m Tc myocardial perfusion imaging. 25 mci of 99mTc tetrofosmin was administered for stress imaging and 8 mci for rest imaging. This person was asymptomatic at 9.1 METS of Bruce protocol on treadmill exercise. Lateral wall is seen to be well perfused and there is no infarct in the lateral wall. Non transmural infarct is seen in the anterior wall, septum and inferior wall. There is very little reversible ischemia. Hence there may not be any benefit from revascularisation of the coronary artery involved.
