Pyrophosphate (PYP), and Hydroxymethylene Diphosphonate (HDP) are Reliable and Readily Available Tracers for use in Bone Scintigraphy for the Diagnosis of Transthyretin Cardiac Amyloidosis (TTR)

3,3-diphosphono-1,2-propanodicarboxylic acid (DPD) is the most validated tracer for detecting cardiac amyloidosis with bone scintigraphy. PYP and HDP are more readily available in Australia, and considered possible alternatives. We sought to examine experience using HDP and PYP at the Victorian and Tasmanian Amyloidosis Service.
