Ultra-early phase scintigraphy detects ATTR cardiac amyloidosis

In this study, the researchers analyzed imaging in four patients with ATTR-CA and four patients with hypertensive cardiomyopathy (non-CA) who underwent dynamic scintigraphic scanning. They reconstructed planar images every minute from three to 20 minutes and then every five minutes from 25 to 60 minutes after injection. The H/CL ratio was assessed on each planar image. The H/CL ratio on the planar images acquired at five minutes post-injection showed a significant difference between ATTR-CA and non-CA patients, according to the findings.Ultra-early phase  Tc-99m PYP scintigraphy can detect ATTR-CA with 100% sensitivity at five minutes after tracer injection, the group suggests.Attend this session on cardiovascular and pulmonary molecular imaging for all the details.
