概括
即使前列腺MRI呈阴性,34%的男性可能患有临床显著的前列腺癌 (csPCa). 在这些情况下,异常的数字直肠检查和PSA密度 (PSAD) 预测了csPCa,指导了活检决策.
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:
- 怀疑患有前列腺癌 (PCa) 的患者中,多达40%的患者有负的预镜MRI (nMRI).
- 在这些患者中,多达15%的人可能患有临床显著的PCa (csPCa).
- 在nMRI患者中预测csPCa可以帮助避免不必要的活检.
研究的目的:
- 确定多参数MRI (mpMRI) 对csPCa的负预测值 (NPV).
- 评估MRI报告模式对临床实践的影响.
- 通过nMRI识别男性中csPCa的预测因子.
主要方法:
- 一项IRB批准的两样性研究包括685名男性,他们接受了前列腺活检 (2016-2023年) 与预活检MRI.
- 评估机构与非机构MRI报告模式.
- 评估年龄,DRE,PSA,PSA密度 (PSAD) 和MRI报告用于nMRI患者的csPCa预测.
主要成果:
- 在62名nMRI患者中,34%的患者患有csPCa.
- 机构MRI显示的灵敏度 (96%) 和NPV (81%) 比非机构MRI更高.
- 在nMRI男性中,异常的DRE和PSAD≥0.25 ng/ml/cc预测了csPCa.
结论:
- 在接受nMRI的男性中,有34%的人在活检时发现有cspca.
- 机构MRI的NPV高于非机构MRI.
- 异常的DRE和PSAD≥0.25 ng/ml/cc与较高的csPCa发病率有关,尽管nMRI.

Magnetic Resonance Imaging
4.9K
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...
