What is a cardiac PYP scan? DRAFT - UW Medicine

WebUnlike AL, ATTR can be diagnosed without a biopsy, by using a pyrophosphate (PYP) nuclear imaging scan. 7 The PYP localizes to cardiac TTR deposits and is highly sensitive for TTR amyloid. 7 If this myocardial uptake of PYP is deemed strongly positive, TTR amyloidosis can be confirmed. After a positive scan, patients will need TTR DNA ...
