-- The first section of this topic is shown below --

Synonym/Acronym:
PYP cardiac scan, infarct scan, pyrophosphate cardiac scan, acute myocardial infarction scan.

Rationale
To identify myocardial infarcts and evaluate myocardial perfusion.

Patient Preparation

  • 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. No other radionuclide scans should be scheduled within 24 to 48 hr before this procedure. Protocols may vary among facilities.

Normal Findings

  • 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.)
