They underwent PET/CT 5 hours after ¹²⁴I-evuzamitide injection (median net injected activity: 0.97 mCi). Images were assessed visually, then myocardial radiotracer uptake above the blood pool was quantified using multiple metrics, including left ventricular percent injected dose (LV %ID = [LV mean activity concentration/injected activity] x LV activity volume x 100). All amyloidosis participants with cardiomyopathy exhibited visible myocardial uptake, while control participants showed no myocardial uptake. Among amyloidosis participants without cardiomyopathy, 3/4 exhibited myocardial uptake despite no signs of amyloidosis on echocardiogram, magnetic resonance imaging, and/or single-photon emission computed tomography.
