The article summarizes the current experience of the nuclear medicine department of the Chazov National Medical Research Center of Cardiology in the implementation of myocardium scintigraphy with 99mTc-pyrophosphate with the differential diagnosis of the types of cardiac amyloidosis. Causes of false-positive, equivocal and non-diagnostic results, are analyzed. Possible ways to eliminate mistakes, including by modifying protocols of planar and tomographic research and optimizing the whole diagnostic algorithm for amyloidosis of the heart, are discussed.
