Multi-Spectral Neural Network (MSNN) Classifier Diagram. Normalized Diffusion Weighted Images (DWI) b-Value (0, 50, 100, 150, 200, 400, 600) serve as inputs to the model, where nodal weights are applied to the hidden and output layers to yield output voxels which are classified as normal, tumor, or background once the model is trained. In all cases, training sets represented a random NF1 subject from the population which has been manually segmented by a trained expert. In the input layer N-, L-, and B-prefixes represent the Normal, Lesion, and Background inputs, respectively, while R-N in each set refers to Registered-Normalized images.
