Technetium Tc 99m pyrophosphate is a radiolabeled bone and cardiac imaging agent that has become the preferred non-invasive scintigraphic test for diagnosing transthyretin cardiac amyloidosis (ATTR-CA), where it accumulates in amyloid-laden myocardium. See technetium-pyrophosphate for complete pharmacological details. It is also used in standard bone scintigraphy and historically for infarct-avid myocardial imaging.
