Molecular Imaging of Cardiac Amyloidosis.

Transthyretin and light-chain amyloidosis are the 2 main causes of cardiac amyloidosis. Recent developments in molecular imaging have transformed our ability to diagnose transthyretin cardiac amyloidosis noninvasively and unmasked a hitherto unrecognized prevalence of the disease. This review summarizes the current and evolving imaging approaches, their molecular structural basis, and the gaps in imaging capabilities that have arisen as a result of parallel developments in pharmacotherapy delivering the first effective treatment options for this condition.
