What the trial is, and whether it could suit you
The primary objective of this study is to evaluate the effectiveness of visual reading in XTR004 PET myocardial perfusion imaging (MPI) for detecting restrictive stenosis, using quantitative coronary angiography (QCA) and fractional flow reserve (FFR) as reference standards in patients with suspected or known coronary artery disease.
