概括
在手术前的胺质子转移加权 (APTw) 核磁共振成像显示,对评估直肠腺癌 (RA) T阶段和周围神经侵入 (PNI) 有希望. 较高的APTw信号强度与高级T阶段和阳性PNI相关,有助于治疗规划.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 结直肠腺癌 (RA) 需要准确的预后因素评估才能有效治疗.
- 目前用于分阶段和确定围神经侵入 (PNI) 的方法存在局限性.
研究的目的:
- 评估手术前的阿米德质子转移权重 (APTw) 核磁共振成像在评估RA的预后因素中的实用性.
- 确定APTwMRI是否可以在RA中非侵入性地评估T阶段和PNI.
主要方法:
- 一项前性研究招募了51名患有RA的参与者,他们接受了手术前的MRI和手术.
- 分析了APTw信号强度 (SI) 值,并对不同T阶段和PNI状态进行了比较.
- 统计分析包括曼·惠特尼U测试,t测试和ROC曲线分析.
主要成果:
- 与T1-T2相比,T3-T4阶段RA的APTwSI值 (最大,99分,95分百分位) 在T1-T2阶段显著更高 (p <0.05).
- 与非PNI病例相比,具有阳性PNI的RA中APTw SI值也显著更高 (p < 0.05).
结论:
- 手术前的APTwMRI是评估T阶段和RA中的PNI的一个有价值的工具.
- APTw MRI提供了一种定量,非侵入性的方法,以帮助精确规划RA患者的治疗.

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,...
