Figure 5: ROC curves for six features and for multilayer perceptron neural network (All features). Az values of two vessel morphologic features—number of vascular trees (Nv) and total vessel length (L1)—were significantly higher than Az value of vessel amount (P = .04 and P = .03, respectively). Az value for multilayer perceptron neural network with all six features produced in the best performance, with Az value of 0.92. Rv = vessel-to-volume ratio, L2 = longest path length, Bn = number of bifurcations, Dv = vessel diameter.
