We try to evaluate the additive diagnostic value of a 3T whole-heart CE-MRCA integration into a CMR-MPI/LGE protocol for the detection of coronary artery disease A total of 38 subjects were examined by CMR (including CMR-MPI, MRCA, and LGE)[j1] and x-ray invasive coronary angiography (ICA). Diagnostic performances of MRCA, CMR-MPI/LGE, and MRCA+CMR-MPI/LGE integration were determined having XA as standard for coronary artery disease. In per-vessel analysis, integrated protocol (AUC=0.84) performed better than the isolated CMR-MPI/LGE (AUC=0.63). In this suspected or known coronary artery disease population, integration of CE-MRCA significantly improved per-vessel diagnostic accuracy of a comprehensive 3T CMR-MPI/LGE protocol.
