Example of images and quantitative perfusion results in a patient with right coronary artery obstruction, red curve: stress arterial input function, white curve: rest arterial input function. Arrows indicate perfusion defect in right coronary artery territory Abbreviations: AIF: arterial input function; MBF: myocardial blood flow; MPR: myocardial perfusion reserve; rMBF: relative myocardial blood flow; rMPR: relative myocardial perfusion reserve. p=0.011 p=0.037 Stress MBF Rest MBF Ischemic myocardium 1.89 ± 0.41 1.13 ± 0.18 Non-ischemic myocardium 2.41 ± 0.57 1.00 ± 0.17 Figure 4. Comparison of stress and rest myocardial blood flow between ischemic and non-ischemic myocardium Abbreviations: MBF: myocardial blood flow Table 2 and Figure 5 show results of expert assessment of image quality by two independent level 3 CMR imaging readers. The overall impression of the quality of the majority of cases was assessed as at least moderate by both readers. Moreover, the
