脑卒中成像脑卒中成像

背景情况:

评估中风的严重程度和预后对于治疗决策至关重要.
像FLAIR和MR血管造影等先进的成像技术提供了对缺血性中风病理生理学的见解.

研究的目的:

在FLAIR成像上验证超强船舶标志 (HVS).

主要方法:

对急性缺血性中风患者的回顾性分析,其中包括内动脉或中脑动脉封闭.
基于HVS (高/低) 和PCA横向性 (正/负) 的分类.
核心和半阴影体积和神经结果的比较.

主要成果:

高HVS组显示较小的核心体积 (32毫升对109毫升) 和更好的结果 (mRS3对5).
高HVS组在随访时具有更大的半阴影体积 (68毫升 vs 0毫升).
PCA横向性没有显示核心或半阴影体积或结果的显著差异.

结论:

在FLAIR成像中显著的HVS与较小的心脏病核心,持久的半阴影和有利的结果有关.
在急性缺血性中风中,HVS可以作为一个有价值的预后标志物.

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...
