Overview
Positron emission tomography is of particular value in the assessment of regional coronary blood flow reserve, myocardial perfusion, and the presence and extent of hibernating myocardium.
PET
- Rubidium-82 or ammonia (N13) can be used for assessment of myocardial perfusion.
- Labeled carbohydrates such as fludeoxyglucose F-18, lipids, and some amino acids can be used to asses myocardial metabolism and viable ischemic myocardium.
Indications
PET is of value principally in difficult situations where in myocardial perfusion by thallium scintigraphy and assessment of left ventricular systolic function by echocardiography do not reveal the extent of hibernating myocardium.
Sensitivity and Specificity
With combined assessment of myocardial perfusion and metabolism, the sensitivity and specificity for the detection of CAD may approach 95%.
Disadvantages
Positron emission tomography is a very expensive noninvasive test and not readily available in every cardiac diagnostic care center.
