Q-23. Which test is performed to detect reversible myocardial ischemia? (NEET Based)
a) Coronary angiography
b) MUGA Scan
c) Thallium Scan
d) Resting echocardiography
Answer: Thallium Scan
See above explanation.
PET is generally regarded as the gold standard for the assessment of myocardium viability. PET identifies ischemic or hibernating myocardium in 10-20 % of the regions that would be classified as fibrotic or infracted by thallium and technetium labeled compounds.
Viable myocardium is myocardium which due to ischemia does not contract normally at rest but has the potential to recover its function, either by itself over time or after revascularization.
