概括
磁共振成像 (MRI) 可以准确量化皮肤性脏活检 (PRB) 后的周围瘤 (PH) 体积. 这种无辐射的方法为评估PH并发症提供了有价值的替代方案.
科学领域:
- 腎臟病學 (nephrology) 是一種醫學.
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 皮肤脏活检 (PRB) 是诊断脏疾病的标准,但可能会导致诸如周围脏血瘤 (PHs) 等出血并发症.
- 超声波低估了PH体积,而CT涉及辐射和对比介质问题.
- 磁共振成像 (MRI) 在PRB后的PH评估中未得到充分利用,尽管其安全性和高分辨率.
研究的目的:
- 评估基于MRI的细分的准确性,以量化PRB后的PH体积.
- 为了评估MRI作为一种补充成像方式,与超声波和CT一起用于PH评估.
主要方法:
- 对接受PRB的85名患者的MRI数据进行了回顾性分析.
- 用于MRI衍生PH体积测量的手动细分.
- 核磁共振成像结果与以前基于CT的研究数据和临床参数的比较.
主要成果:
- 在74.1%的患者中检测到PH,平均MRI体积为26.2毫升 (小于CT衍生体积).
- 在PH体积和血清肌素 (Cr) 和静脉血压 (SBP) 之间发现了积极的相关性.
- PH体积和血红蛋白水平之间的负相关性;血液透析与更大的PH相关 (OR=4.59).
结论:
- 磁力共振成像是一种可行的,无辐射和无对比度的工具,用于PRB后的详细PH评估.
- 核磁共振可以作为一种补充成像方式,特别是当不需要立即做出关键决策时.
- 需要进一步验证与血液透析和PH大小相关的发现.

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,...

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...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...
