AI assistance is associated with a superior improvement in detecting clinically significant prostate cancer on MRI, a diagnostic study finds.
detection on MRI, increasing diagnostic accuracy by 3.3% compared with unassisted readings. AI support enhanced both sensitivity and specificity at detecting clinically significant prostate cancer .Researchers conducted a diagnostic observer study in which 61 readers across 17 countries assessed 360 MRI examinations of men with prostate cancer with and without AI assistance.
The AI system used in this study was curated and developed within the international Prostate Imaging-Cancer AI Consortium for the detection and diagnosis of csPCa. The primary objective was to assess whether AI-assisted csPCa diagnosis was superior to unassisted diagnosis at the patient level using the area under the receiver operating characteristic curve , sensitivity, and specificity at a Prostate Imaging Reporting and Data System threshold of 3 or more.Likewise, the specificity was 50.1% for AI-assisted vs 46.7% for unassisted assessments, showing an improvement of 3.4%. Non-expert readers showed greater performance improvement with AI assistance than expert readers, achieving higher AUROC scores than those of unassisted experts."The findings of this diagnostic study suggest the potential of AI assistance in improving csPCa diagnosis when compared with unassisted assessments of biparametric MRI, with statistically significant improvements observed across AUROC, sensitivity, and specificity at a PI-RADS score of 3 or more. Notably, nonexpert readers demonstrated higher benefits from AI assistance compared with expert readers," the authors wrote.This study was led by Jasper J. Twilt, MSc, Minimally Invasive Image-Guided Intervention Center, Department of Medical Imaging, Radboud University Medical Center, Nijmegen, the Netherlands. It wasThe data included were retrospectively curated within the scope of PI-CAI, resulting in a mix of consecutive and sampled cohorts. The study's generalisability requires further validation across external cohorts with varying disease prevalence, image quality, and other clinical factors. The controlled online reading workstation environment differed from readers' native settings, potentially affecting diagnostic performance. This study did not assess workflow efficiency or the clinical applicability of performance improvements in real clinical settings.This study received funding support from Health-Holland and the European Union's Horizon 2020.
