Webb4 feb. 2024 · High-grade (Perugini grade 2 or 3) cardiac uptake on bone scintigraphy with 99m Technetium labelled 3,3-diphosphono-1,2-propanodicarboxylic acid ( 99m Tc-DPD) has lately been confirmed to have high diagnostic sensitivity and specificity for cardiac transthyretin (ATTR) amyloidosis. Webb1 okt. 2024 · Imaging with technetium labeled bone-avid tracers is highly sensitive and specific for the non-invasive identification of transthyretin cardiac amyloidosis (ATTR-CA), when used in the proper clinical context. The mechanism of myocardial radiotracer uptake is unclear, possibly related to calcium incorporated into amyloid deposits.
