Based on multi-center cohorts, AI model could independently diagnose PCa with remarkable false negative and sensitivity. For the diagnosis performance, although AI performed suboptimal, the human-led synergy method performed equivalent to clinical assessment with improved consistency.
The flowchart of the study. PCa: prostate cancer; BPH: benign prostatic hyperplasia.
Artificial intelligence architecture. a. Small Vnet (sVnet), based on V-Net with modifications, composed of one input block, four downsampling blocks (Down Block), four upsampling blocks (Up Block), four merge blocks (Merge Block) and one output block. The horizontal arrow denotes the transfer of residual information from the early stage to the later stage. b. Multi-small Vnet (msVnet), where two sVnets are cascaded.
