概括

多参数MRI (mpMRI) 和向活检可靠地检测在积极监测 (AS) 的患者中具有临床意义的前列腺癌 (csPC). 单独的向活检可能足以在AS患者中检测cspc.

科学领域:

泌尿器科泌尿器科泌尿器科泌尿器科
在瘤学瘤学.
放射学放射学是一门学科.

背景情况:

前列腺癌的积极监测 (AS) 需要定期监测疾病进展.
多参数磁共振成像 (mpMRI) 和向活检是AS的关键工具,但它们的诊断价值需要澄清.

研究的目的:

为了比较mpMRI (PI-RADS 3-5病变) 和针对活检的诊断产量,在积极监测中的患者与非AS患者之间进行活跃监测.
评估单独的向活检是否足以检测AS患者的临床显著前列腺癌 (csPC).

主要方法:

对600名患者 (158名AS,442名非AS) 的回顾性研究,这些患者接受了mpMRI和活检 (2017-2022).
比较PI-RADS分数分布和AS群与非AS群之间针对性活检中的CSPC检测率.
后勤回归分析以确定AS状态和结果之间的关联;综合活检产量的评估.

主要成果:

在AS和非AS组之间,PI-RADS分数分布或cspc检测率没有显著差异 (32%与30%对比).
积极监视状态与PI-RADS得分的csPC检测率没有关联.
添加系统活检并没有显著改善AS患者的CSPC检测 (36%对32%).

结论:

mpMRI可疑PI-RADS 3-5病变对于AS患者的csPC诊断是可靠的.
单独的向活检可能足以在AS中检测cspc,从而可能简化监测协议.
建议进行进一步的前性研究,以验证这些发现,并完善AS的活检策略.

Magnetic Resonance Imaging

Magnetic Resonance Imaging

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...

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,...

Radiological Investigation II: MRI and Ventilation Perfusion Scan

Description
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
