99mTc-PYP scintigraphy has been used for diagnosing transthyretin cardiac amyloidosis. However, its quantitative analysis has not been fully established. We aimed to examine the SUVs in the heart, aorta, and lungs using SPECT/CT images, and compared them with the conventional visual assessment. SUVmean in the heart was higher in the amyloidosis group than in the non amyloidosis group. Compared with SUVmean in the heart, the ratio of SUVmean in the heart and aorta(SUVratio(H/Ao))provided us a better cut-off for diagnosing cardiac amyloidosis.
