Fig. 3From: Neural-network classification of cardiac disease from 31P cardiovascular magnetic resonance spectroscopy measures of creatine kinase energy metabolism(a) Receiver operating curve (ROC; the true positive rate or sensitivity vs. the false positive rate, or 1-specificity) analyses of the network’s classification of healthy control subjects (green); patients with HF (red); and those with MI (blue) and HCM (magenta), both without HF. The areas under the curve (AUC) are 0.94, 0.92, 0.95 and 0.98, respectively. (b) Three-dimensional (3D) plot of the independent variables [PCr], [ATP] and kf depicting the network’s correct (solid symbols) and incorrect classificationsBack to article page
