Technetium Pyrophosphate Scan
This scan uses the radioactive isotope Tc-99m pyrophosphate to evaluate whether an unusual type of abnormal heart muscle function (cardiomyopathy) is present. An intravenous injection of pyrophosphate is made at rest, followed about an hour later by a set of images taken while you lie down under a camera.
These images are recorded on a computer for analysis.
The images take about 15 minutes. The entire procedure, from injection to end of imaging, takes about two hours.
