Innovative technology performs automatic segmentation and lesion detection in prostate MRI scans to assist in PI-RADS scoring for prostate cancer management TEL AVIV, Israel & SAN JOSE, ...

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 ...

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 ...

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

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 ...

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 ...

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