Evaluation of Motion Correction on Myocardial [18F]F-AraG PET Uptake Using Data-Driven Respiratory Gating

Abstract

[18F]F‐AraG (radio‐fluorinated 9‐β‐D‐arabinofuranosylguanine) is a PET radiotracer for imaging T‐cell activation with emerging applications in myocardial imaging. Cardiac PET is particularly susceptible to respiratory motion, which degrades spatial resolution and introduces regional variability in quantitative measurements.
