本研究针对重复前列腺活检中PI-RADS 3病变的诊断挑战，通过回顾性分析684例患者数据，发现PI-RADS 3是阴性活检的独立预测因子（OR 0.582），而PSA密度（PSAD）在PI-RADS 4-5病变中具有显著风险分层价值（62.4% vs 33.8%），在PI-RADS 3中则差异有限（20.7% vs 16.2%）。该研究为 ...

前列腺癌检测中，外周带T2信号强度指数（PZ_Si2）对PI-RADS v2.1≥3病灶的PCa和CsPCa检测AUC分别为0.89和0.86，最优阈值≤5.25可减少42 ...

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 ...

68 Ga-PSMA PET/MRI examples of PRIMARY scores. T2WI = T2-weighted image; PZ = peripheral zone; CZ = central zone. Reston, VA—PET/MRI can improve diagnostic accuracy for prostate cancer patients and ...

An artificial intelligence system slightly outperformed radiologists using PI-RADS at detecting clinically significant prostate cancer. A trained artificial intelligence (AI) system discriminated ...

Prostate MRI currently lacks the accuracy to replace biopsies in active surveillance for prostate cancer. The negative predictive value of MRI remains below 90%, the general goal for safely avoiding ...

Adding baseline MRI to conventional prostate cancer risk stratification could improve prognostic accuracy, potentially affecting active surveillance and treatment decisions for some patients, ...

At repeat screening, only a low proportion of MRI scans indicated suspicion of clinically significant prostate cancer. Among men receiving their second biennial prostate cancer screening in a Swedish ...

PET/MRI can improve diagnostic accuracy for prostate cancer patients and help avoid unnecessary biopsies, according to new research published in the April issue of The Journal of Nuclear Medicine. By ...

MRI of the prostate, combined with a blood test, can help determine if a prostate lesion is clinically significant cancer, new research suggests. A new meta-analysis by investigators from Brigham and ...
