Novel radiotracer demonstrates high diagnosti

A novel PET perfusion radiotracer, 18F-flurpiridaz, can diagnose coronary artery disease (CAD) in obese patients with a higher sensitivity and specificity compared to 99Tc-SPECT myocardial perfusion imaging (MPI), according to research presented at the 2023 Society of Nuclear Medicine and Molecular Imaging Annual Meeting. 18F-flurpiridaz PET MPI obtained images at a lower radiation dose than 99Tc-SPECT MPI and performed similarly in both obese and non-obese patients.
