Figure 6. Case of a 60-year-old male with echocardiography consistent to hypertrophic cardiomyopathy, preserved ejection fraction. Pericardial effusion. Technetium-99m 3,3-diphosphono-1,2-propanodicarboxylic acid bone scan performed for clinical suspicion of cardiac amyloidosis revealed mild uptake in heart area, but single photon emission computed tomography/computed tomography demonstrated that it is due to blood pool activity: visual score 0.
