Figure 2

(A) Anterior and posterior whole body 99mTc-DPD scan images of a 64-year-old male patient with AL subtype of cardiac amyloidosis show equivocal mild 99mTc-DPD uptake in the cardiac area. It is unclear whether that uptake is related to cardiac amyloidosis because there was pericardial effusion on chest X-ray and echocardiography. (B and C) On the additional SPECT/CT image, the 99mTc-DPD uptake does correspond to the myocardium, suggesting cardiac amyloidosis. On the contrary, there is no significant 99mTc-DPD uptake in the pericardial effusion on the SPECT/CT image.
