carDIo-ttranSSfOrm nucLEar Imaging Study (DISSOLvE)
February 17, 2022 updated by: Oregon Health and Science University
The investigators will evaluate the change in myocardial uptake of 99m-technetium pyrophosphate (Tc-99m PYP) tracer on serial planar and SPECT imaging in patients enrolled in the CARDIO-TTRansform clinical trial (NCT04136171).
