Abstract
A computer-aided detection and classification system for prostate cancer (CaP) is proposed. The system features the ability to generate a prediction map of the prostate for biopsy planning. Also, the system is able to incorporate multiple MRI modalities. The performance of the proposed system was tested on a dataset of 26 CaP patients with T2-weighted and Diffusion-weighted MRI imaging (15 training and 11 testing cases). A significant improvement in area under the receiver operating curve (AUROC) was obtained (p < 0.0001) when both imaging modalities were utilized (AUROC = 85.4%) compared with when only the T2-weighted images were used (AUROC = 82.6%). Additionally, the generated prediction maps show promise in aiding clinicians with tumor detection.
