Figure 2. Receiver operating characteristic (ROC) curves for detecting benign prostatic hyperplasia (BPH) or non-clinically significant prostate cancer (non-csPC) by the radiologists and the AI system. The area under the ROC curve (AUROC) by the AI system is 0.813, and by the radiologists is 0.695. The sensitivity and specificity by the AI system are 86.8% and 59.4%, respectively, while those by the radiologists are 84.2% and 28.1%, respectively. AI: Artificial intelligence.
