概括

扩散加权全身成像与背景抑制 (DWIBS) 核磁共振扫描检测出一个患有复发性缺血性发作的患者的胸前大动脉炎症. 这种无辐射成像技术在诊断大动脉炎症方面表现有前途.

科学领域:

心血管成像 - 心血管成像
放射学放射学是一门学科.
血管医学血管医学

背景情况:

一名75岁的男性有胸前大动脉剖析和支架的病史,出现了反复的脑缺血性发作.
包括CT和超声波在内的初步评估没有确定炎症标志物 (CRP,D-二次体) 和微细胞贫血的来源.

研究的目的:

调查扩散加权全身成像与背景身体信号抑制 (DWIBS) MRI 在检测大动脉炎症中的实用性.

主要方法:

一名患者接受了连续成像,包括用DWIBS进行MRI,在初步检查未解释的炎症标志物和缺血事件后进行了连续成像.
用增强对比度的CT用于评估大动脉病变和并发症.

主要成果:

德维布斯MRI显示胸前大动脉的强度过高,表明有炎症.
较量增强CT后来证实了大动脉壁增强和肺炎.
患者患有血栓塞,导致由于怀疑主动脉支架瘤,紧急插入支架移植.

结论:

使用DWIBS的MRI有效地在没有辐射或对比剂的情况下识别出胸前大动脉炎症.
作为一个具有成本效益的成像工具,DWIBS显示出显著的潜力,用于诊断和评估大动脉炎症.

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...
