Figure 5:

Histogram demonstrating image quality scores for the clinical native T2prep-bSSFP versus bright-blood MTC-BOOST imaging. Summary of the image quality scores with regard to sharpness of vessel or cardiac wall borders and robustness to artifact (120 clinical examinations averaged across four reviewers and 120 research examinations averaged across four reviewers). Vessel sharpness and artifact scoring color correspondence is provided next to the respective color bar. The x-axis reflects percentage of examinations. A maximal image quality score of 5 for vessel sharpness indicates sharp delineation of all relevant anatomic structures with excellent contrast, whereas a robustness-to-artifact score of 5 reflects no ghosting, signal voids, or cardiac motion blurring (Appendix S3). AA = ascending aorta, IVC = inferior vena cava, LA = left atrium, LLPV = left lower pulmonary vein, LMCA = left main coronary artery, LUPV = left upper pulmonary vein, LV = left ventricle, MPA = main pulmonary artery, MTC-BOOST = Magnetization Transfer Contrast Bright-and-black blOOd phase SensiTive, RA = right atrium, RCA = right coronary artery, RUPV = right upper pulmonary vein, RV = right ventricle, SVC = superior vena cava, T2prep-bSSFP = T2-prepared balanced steady-state free precession.
