Assessment of incidental cardiac uptake in bone scintigraphy across Spain: The ECCINGO study.

Aim: Myocardial uptake on bone scintigraphy has become useful for the detection of transthyretin cardiac amyloidosis (ATTR-CA). This study aimed to assess the prevalence of myocardial uptake in patients over 18 years of age with no clinical suspicion of cardiac amyloidosis (CA) who had undergone bone scintigraphy.

Methods And Results: This was an observational, retrospective, multicenter study across 21 Spanish hospitals (September-November 2019).
