概括
操作人员的经验对前列腺癌 (PC) 和临床上显著的前列腺癌 (csPC) 检测使用MRI-TRUS-融合活检的影响最小. 在PI-RADS 4-5中高cspc检测支持针对性的仅活检方法.
科学领域:
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
背景情况:
- 标准化的MRI/TRUS融合活检协议越来越多地用于前列腺癌 (PC) 检测.
- 操作人员的经验是影响这些活检技术有效性的潜在因素.
研究的目的:
- 分析操作员经验对PC和临床显著PC (csPC) 检测的影响,使用标准化的MRI/TRUS融合活检协议.
- 评估数字直肠检查 (DRE) 和PI-RADS评分在PC检测中的诊断价值.
主要方法:
- 在2019-2024年期间,对683名接受MRI/TRUS融合活检 (透直肠,软件辅助) 的男性进行了回顾性分析.
- 经营者被分为经验子组 (<100 vs. ≥100程序).
- 评估的数据包括临床信息,MRI发现和活检结果 (向活检[TB]和系统活检[SB]).
主要成果:
- 总体PC和csPC检测率分别为67%和51%,基于操作员经验没有显著差异 (p=0.63和p=0.23).
- 通过SB或TB进行额外的csPC检测在经验子组之间没有显著差异 (p=0.31和p=0.93).
- DRE显示的诊断值有限 (SEN 32%,SPE 88%,PPV 74%,NPV 55%) 没有与经验相关的显著变化 (p=0.12-1.0).
结论:
- 在标准化MRI向活检环境中,操作人员的经验对PC和csPC检测的影响有限.
- 在PI-RADS 4-5病变中高cspc检测率支持针对性的仅活检方法.
- 在PI-RADS 3病变中检测率低,建议考虑随访MRI而不是立即活检;由于精度有限,DRE在PC评估中的作用正在下降.

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...
