Conventional coronary magnetic resonance angiography (CMRA) is limited by long and unpredictable acquisition-times, low spatial resolution and motion related image quality degradation. To overcome these challenges, we have proposed a highly undersampled acquisition with image-based navigators and non-rigid motion correction to enable high resolution (0.9mm3) CMRA with ≈11min acquisition time. In 30 patients with suspected coronary artery disease (CAD) who also underwent a coronary computed tomography angiography (CCTA), our CMRA framework achieved excellent image quality across all coronary artery segments, with a per patient sensitivity of 100%, specificity of 68% and negative predictive value of 100% for identifying/excluding significant CAD.
