True positive (TP); False positive (FP) True negative (TN); False negative (FN) | MR spectrum image metabolite features (in %) | MR image GLCM texture features (in %) |
Sensitivity = TP/TP + FN (%) | 92.2 | 85.7 |
Specificity = TN/FP + TN (%) | 90.1 | 78.6 |
Accuracy = TP + TN/TP + FN + TP + TN (%) | 90.8 | 82.1 |
