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. 2

80-year-old male patient with pre-test probability of CAD of 37% (CAD consortium (%)- basic model). a cCTA demonstrates a high-risk plaque in the main stem of the left coronary artery and in the proximal left anterior descending coronary artery (arrow). b CT-FFRML software provides a color-coded 3-dimensional mesh of the coronary tree and calculated a value of 0.98 in an area distal of the stenosis (arrow). c Stress perfusion CMR in three short axis slices shows no perfusion deficit and thus no myocardial ischemia. 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
