前列腺MRI PI-RADS 3评分解读中不同经验放射科医生的组间一致性及诊断效能研究。通过回顾性分析133例病理证实病例，发现组间kappa值仅0.149，与Gleason评分弱相关（t=0.197），但不同经验医生对PI-RADS 3评分的判断无显著差异。研究强调需优化解读流程和补充决策规则。

本研究针对PSA≤20 ng/mL人群前列腺癌诊断难题，开发了融合双参数MRI的PI-RADS v2.1评分与临床指标的列线图模型。研究通过LASSO回归筛选出PI-RADS v2.1、%fPSA、ADC值和血红蛋白四个独立预测因子，模型在训练集和验证集的AUC分别达0.922和0.898，显著优于单一指标诊断效能 ...

Upgrade and downgrade rates from targeted biopsy to radical prostatectomy were not significantly different between patients whose MRI examinations were clinically interpreted using PI-RADS Version ...
