Abstract: Transthyretin (TTR) cardiac amyloidosis (CA) is an increasingly recognized cause of heart failure. Diagnosis of TTR-CA relies on visual and semi-quantitative interpretation of planar 99mTc-PYP imaging. However, new methods that directly quantify PYP uptake may… read more here.

Abstract: ABSTRACT Transthyretin cardiac amyloidosis (ATTR and ATTRv) is an underrecognized cause of heart failure that results from myocardial deposition of misfolded protein (TTR or prealbumin). The diagnosis can be confirmed by uptake of 99mTc-pyrophosphate (99mTc-PYP)… read more here.

Abstract: Purpose 99mTc-pyrophosphate (99mTc-PYP) uptake in the skeletal muscles is minimal in patients with transthyretin cardiac amyloidosis (ATTR-CA) when assessed qualitatively and quantitatively. We previously demonstrated moderate- to high-grade 99mTc-PYP uptake in the subcutaneous abdominal fat… read more here.

DOI: 10.3390/diagnostics12010094
Abstract: Background: Two different approaches, 1-h heart-to-contralateral (H/CL) ratio and 3-h visual grading scale relative to ribs (VGSr), have been established to interpret 99mTc-PYP planar images for the detection of amyloid transthyretin cardiac amyloidosis (ATTR-CA). Since… read more here.
