概括

多参数MRI (mpMRI) 上的小体积指数病变经常是临床上显著的前列腺癌. 用MRI指导的活检对于准确的表征至关重要,因为仅仅是病变大小并不排除癌症.

科学领域:

尿道瘤学尿道瘤学
放射学放射学是一门学科.
病理学病理学病理学

背景情况:

在多参数MRI (mpMRI) 上越来越多地检测到小体积指数病变.
这些小病变的临床意义需要进一步调查.

研究的目的:

为了评估mpMRI检测到的小体积指数病变的意义.
为了确定癌症检测率和这些病变的特征,使用MRI引导的孔内活检.

主要方法:

对107名患有外围区域PI-RADS 4病变 (≤7毫米) 的患者进行了回顾性审查.
对患者人口统计,PSA水平,PSA密度,病变特征以及国际泌尿病理学会 (ISUP) 评级组的分析.
这些因素与活检结果的相关性.

主要成果:

前列腺癌 (PCa) 在66.3%的患者中检测到,其中43.9%的患者具有临床显著的PCa (csPCa).
线性形病变显示PCa检测率为61.1%和csPCa检测率为48.1%.
几乎一半的小体积指数病变具有临床意义,不论形状如何.

结论:

在mpMRI上的小体积指数病变经常存在临床上显著的前列腺癌.
仅仅是损伤大小就不足以省略活检;MRI引导的孔内活检对于准确的评估至关重要.

关键词:

磁力共振成像 (MRI) 路径在钻孔内进行活检.mpMRI 的时间.前列腺癌是前列腺癌.形状形状形状形状小小的体积小的体积小的体积

Imaging Studies IV: Magnetic Resonance Imaging

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,...
