本研究对比了PI-RADS v2.1与v2.0在多参数MRI（mpMRI）诊断临床显著前列腺癌（csPCa）中的性能。结果显示，v2.1通过优化移行带（TZ）病灶评估标准，显著提升了TZ区域csPCa的检出率（55.1% vs 39.3%），且多变量分析证实其优势（OR=1.34）。研究证实v2.1在标准化前列腺影像 ...

前列腺癌PI-RADS 5级病灶中11.4%活检阴性，通过多因素分析发现前列腺体积＞60cc、正常DRE、既往阴性活检、过渡区病灶及TRUS未发现可疑低回声是独立预测因素，联合应用可提升诊断准确性至AUC≥0.84，为个体化随访策略提供依据。 多参数磁共振成像（mpMRI）在前列 ...

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 ...

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

When the PSA is elevated: for which men is a biopsy necessary to confirm or rule out suspected prostate cancer? In a retrospective study, scientists from the German Cancer Research Center (DKFZ) and ...

An artificial intelligence (AI) system was better at detecting clinically significant prostate cancer on MRI compared with radiologists, a noninferiority, confirmatory study showed. In a subset of 400 ...

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 ...

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 ...
