In the present study, we propose a multi-layer artificial neural network (ANN) model integrating MR images (T2 weighted imagesdiffusion weighted images, dynamic contrast enhanced images and MR spectroscopy) and clinical examination (Total PSA value, free/total PSA ratio and age) for prostate cancer detection. The new model is able to provide high accuracy in detection of prostate cancer through proper training. Significant improvement in the AUC can be produced when compared to clinical-only model, and this demonstrates the capacity of MRI for computer-aided prostate cancer identification.
