From: Stable patients with suspected myocardial ischemia: comparison of machine-learning computed tomography-based fractional flow reserve and stress perfusion cardiovascular magnetic resonance imaging to detect myocardial ischemia

Fig. 3

53-year-old male patient with suspected CAD and arterial hypertension. a cCTA illustrates a moderately graded stenosis (50–69%) with unclear hemodynamic relevance caused by mixed structured plaques in the mid left anterior descending coronary artery (arrow). b Color-coded 3-dimensional mesh created by CT-FFRML software shows a flow-limiting stenosis with a measured value of 0.77 (arrow). c a midventricular short axis stress perfusion CMR image demonstrates a significant perfusion deficit in the left anterior descending coronary artery territory, which correlates with the myocardium subtended by the hemodynamically significant lesion identified on CT-FFRML; CAD = coronary artery disease; cCTA = coronary CT angiography; CT-FFRML = Fractional flow reserve derived from coronary computed tomography angiography based on machine learning algorithm; CMR = cardiovascular magnetic resonance imaging
