headline: Artificial intelligence in the radiologic diagnosis of major urological cancers: a meta-analysis
dek: Objective Given the pivotal role of imaging in diagnosing urological cancers, artificial intelligence (AI) has emerged as a promising tool to improve diagnostic accuracy and reliability. This study systematically evaluates the diagnostic performance of AI models in radiologic imaging of urological cancers. Methods A systematic search was conducted in four electronic databases up to June 2026 to identify studies that applied AI algorithms for the diagnosis of urological cancers using CT, MRI, or ultrasound. Eligi…
gain_title: AI models for CT, MRI, and ultrasound diagnosis of urological cancers achieved higher pooled specificity and AUC than clinicians in a 110-study meta-analysis.
problem_title: In prostate cancer and MRI subgroups, AI models showed lower sensitivity than clinicians, indicating inconsistent advantage across tasks.
trace_subject: diagnostic accuracy of AI versus clinicians in radiologic imaging of urological cancers
gain_reading: AI models for CT, MRI, and ultrasound diagnosis of urological cancers achieved higher pooled specificity and AUC than clinicians in a 110-study meta-analysis.
gain_evidence: AI models achieved pooled sensitivity and specificity of 0.85 (95% CI: 0.83-0.87) and 0.83 (95% CI: 0.80-0.86), with an AUC of 0.91 (95% CI: 0.88-0.93)
problem_reading: In prostate cancer and MRI subgroups, AI models showed lower sensitivity than clinicians, indicating inconsistent advantage across tasks.
problem_evidence: although clinicians demonstrated higher sensitivity in the prostate cancer and MRI subgroups
quick_read: A meta-analysis of 110 studies up to June 2026 evaluated AI algorithms for diagnosing urological cancers on CT, MRI, and ultrasound, pooling sensitivity, specificity, and AUC and comparing to clinician performance where reported.

The pooled results suggest AI could improve specificity and overall discrimination in urology imaging workflows, but the retrospective nature of included studies and lower AI sensitivity in prostate and MRI subgroups leave uncertainty about real-world clinical utility pending prospective multi-center testing.
limitation: Findings are based on retrospective pooled studies with heterogeneity, requiring further prospective validation before clinical adoption.
tag: Automated dual reading
key_points: Systematic search of four databases up to June 2026 identified 110 eligible studies using CT, MRI, or ultrasound with AI algorithms. | Pooled clinician performance was sensitivity 0.82, specificity 0.68, AUC 0.83, compared to AI AUC 0.91. | Study quality was assessed using the QUADAS-2 tool and pooled using a bivariate random-effects model. | Authors concluded AI shows potential as supportive tools in radiological workflows for urological oncology.
rundown: The analysis pooled 110 studies of AI for CT, MRI, or ultrasound diagnosis of urological cancers, using a bivariate random-effects model for sensitivity, specificity, and AUC, with QUADAS-2 quality assessment.

Overall AI outperformed pooled clinician metrics, but subgroup results showed clinicians retained higher sensitivity for prostate cancer and for MRI, highlighting task-dependent variation.
