510 Objectives: Transthyretin cardiac amyloidosis (ATTR) is caused by the extracellular
deposition of amyloid fibrils in the heart and results in diastolic dysfunction, conduction …

Purpose: Transthyretin (ATTR) amyloidosis is a rare but serious infiltrative disease
associated with a wide spectrum of morphologic and functional cardiac involvement. 99mTc …

Abstract Aims High-grade (Perugini grade 2 or 3) cardiac uptake on bone scintigraphy with
99mTechnetium labelled 3, 3-diphosphono-1, 2-propanodicarboxylic acid (99mTc-DPD) has …

Purpose: Few scintigraphic tracers are informative on myocardial amyloid infiltration. We
aimed to assess: the accuracy of 99mTc-DPD scintigraphy in differential diagnosis between …

Abstract Background and Aim Either 99mTechnetium diphosphonate (Tc-DPD) or
pyrophosphate (Tc-PYP) scintigraphy plays a relevant role in diagnosing transthyretin …

Aims: There has been a paradigm shift in diagnosis of cardiac transthyretin amyloidosis
(ATTR) with non-invasive techniques including technetium-99m 3, 3-diphosphono-1, 2 …

Background This study sought to compare the intensity of early-phase myocardial uptake of
two phosphonate-based radiotracers, 99m Tc-hydroxymethylene diphosphonate (HMDP) …

Background The significance of measuring 99mTc-labelled-3, 3-diphosphono-1, 2-
propanodicarboxylic acid (99mTc-DPD) in transthyretin (ATTR) cardiac amyloidosis has not …

Background The aim of this study was to investigate the feasibility of assessing absolute
myocardial 99mTc-HMDP uptake in patients with suspected cardiac ATTR using SUV with a …

Background To determine the capability of 99m Tc-DPD scintigraphy to detect early cardiac
involvement and predict clinical worsening in transthyretin (TTR) gene mutation patients …
