概括

水道管网 (AW) 可以导致水道管狭窄 (AS). 相对照MRI揭示了脑脊液 (CSF) 流动的动态,即使有网络,也显示了水道中的流动,特别是在更宽的前柱水槽和自发的第三腹腔造影中.

科学领域:

神经外科神经外科
放射学放射学是一门学科.
医疗成像医学成像

背景情况:

水道管网 (AW) 是水道管狭窄症 (AS) 的原因之一.
先进的磁共振 (MR) 影像改善了脑脊液 (CSF) 流动动态和水道解剖学的可视化.

研究的目的:

用相对照MRI评估AW患者的CSF流动力学.
将这些动态与其他成像发现进行比较.

主要方法:

评估了23名患者 (65岁以下) 使用T2 CISS和斜空间MRI序列.
测量了前水库 (PPC) 和西尔维亚水道 (SA) 的宽度.
评估了网络存在,水道流和自发的第三腹腔静脉切除术 (STV).

主要成果:

在23名患者中检测到31个AW; 26.1%有STV.
在SPACE序列上,只有17.4%的数据显示了水道流.
在STV患者中更广泛的PPC (p=0.004);较低的Evan指数 (EI) 与流动工件 (p<0.001).

结论:

尽管有网络,但在SA中可能存在流量,如果EI很低.
在PPC距离较远的患者中,考虑STV并评估SPACE序列的流量.

关键词:

在CSF的流量.这就是为什么MRI是MRI.水道管狭窄症的发生.网络网络网络网络网络

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...
