Radiolabeled Thioflavin-T Derivative PET Imaging for the Assessment of Cardiac Amyloidosis.

F-florbetapir, -flutemetamol, and -florbetaben for the detection of cardiac amyloid. While planar imaging currently plays a large role in the workup of CA, PET imaging could play an increasing important role in the future. The quantitative abilities of novel PET tracers could theoretically allow for the serial monitoring of patients and detection of response to therapy, and the sensitive nature of the tracers could allow for even earlier disease detection. Further work with large randomized controlled trial data is needed in the development and validation of PET tracers for cardiac amyloid and represents an exciting development within the realm of nuclear cardiology.
