概括
多参数核磁共振 (mpMRI) 精确检测焦点冷化 (FC) 后的残留前列腺癌 (PCa). 负的mpMRI结果表明可以安全地避免协议活检,改善患者管理.
科学领域:
- 尿道瘤学 尿道瘤学
- 医疗成像医学成像
- 最少侵入性的治疗方法
背景情况:
- 评估前列腺癌 (PCa) 焦点切除后的瘤结果通常涉及前列腺特异性抗原 (PSA) 反应和成像,但协议活检的作用尚不清楚.
- 目前的指导方针建议随访多参数MRI (mpMRI) 和活检,尽管成像质量和活检性能存在差异.
- 在焦点冷化 (FC) 后检测早期,现场复发的mpMRI的诊断性能需要进一步调查.
研究的目的:
- 评估后稳定性mpMRI的性能特征,以识别前列腺癌 (PCa) 焦点冷 (FC) 后的早期现场治疗失败.
- 为了确定mpMRI的灵敏度,特异性,正预测值 (PPV) 和负预测值 (NPV),用于检测格里森等级组 (GG) ≥2PCa后FC.
- 评估结合FC后的mpMRI的协议活检的临床实用性.
主要方法:
- 利用了2017年1月1日至2023年4月21日期间接受PCa的FC患者的前性注册表.
- 患者在FC后6至12个月接受了废除床的mpMRI和超声波-MR融合活检.
- 计算了mpMRI性能指标 (灵敏度,特异性,PPV,NPV) 以检测残留GG≥2PCa,并使用基平方测试进行统计分析.
主要成果:
- 总共分析了84个稳定后事件,mpMRI检测到13.4% (11/84) 的病例持续的PCa.
- 协议活检证实,在目标病变的7.1% (6/84) 中,格里森等级组 (GG) ≥2 PCa.
- 张贴后的mpMRI显示高灵敏度 (83.3%),特异性 (92.3%) 和NPV (98.6%) 检测未经处理的GG≥2PCa,正确的MRI和活检结果之间有显著的关联 (p < 0.0001).
结论:
- 在焦点冷处理 (FC) 后,后置量mpMRI显示出高灵敏度,特异性和负预测值,用于检测剩余格里森等级组 (GG) ≥2的前列腺癌 (PCa).
- 负的mpMRI结果表明,可以安全地省略近期协议活检,从而有可能简化患者的随访.
- 对虚假阳性和虚假阴性mpMRI发现的原因进行进一步的研究是有必要的,以改进患者对协议活检的选择.

Magnetic Resonance Imaging
7.3K
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...

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,...
