Abstract
To automatically identify regions where prostate cancer is suspected on multi-parametric magnetic resonance images (mp-MRI). A residual network was implemented based on segmentations from an expert radiologist on T2-weighted, apparent diffusion coefficient map, and high b-value diffusion-weighted images. Mp-MRIs from 346 patients were used in this study. The residual network achieved a hit or miss accuracy of 93% for lesion detection, with an average Jaccard score of 71% that compared the agreement between network and radiologist segmentations. This paper demonstrated the ability for residual networks to learn features for prostate lesion segmentation.
