Myocardial Infarct Scan
PYP cardiac scan, infarct scan, pyrophosphate cardiac scan, acute myocardial infarction scan.
To identify myocardial infarcts and evaluate myocardial perfusion.
- Instruct the patient to fast, restrict fluids, and refrain from smoking for 4 hr prior to the procedure. Instruct the patient to withhold medications for 24 hr before the procedure. Protocols may vary among facilities.
- Normal coronary blood flow and tissue perfusion, with no pyrophosphate (PYP) localization in the myocardium
- No uptake above background activity in the myocardium (Note: When PYP uptake is present, it is graded in relation to adjacent rib activity.)
