摘要

最近的研究表明,动脉自旋标记(ASL)可以作为评估癫痫持续状态(SE)的一种有价值的工具,因为它显示了致痫灶的高灌注。然而,ASL在描述病变的精确位置方面并不是特别有效。本例患者为33岁男性,癫痫持续状态,在4 h内进行了MAGiC序列扫描。MAGiC序列可以在一次扫描中生成10张对比图像和5张定量图。在此框架下,弥散加权成像(DIR-WM)序列通过抑制脑脊液和灰质的信号来增强对比度,从而使白质病变(包括致癫痫性海马)在患侧更容易识别。

ASL combined with MAGiC facilitates the identification of patients with status epilepticus.

Recent studies suggest that arterial spin labeling (ASL) can be a valuable tool in the assessment of status epilepticus (SE), as it reveals hyperperfusion in epileptogenic foci. However, ASL is not particularly effective in delineating the precise location of the lesion. In this case, the patient, a 33-year-old male with status epilepticus, underwent MAGiC sequence scanning within 4 h. The MAGiC sequence can generate ten contrast images and five quantitative maps in a single scan session. Within this framework, the diffusion-weighted imaging (DIR-WM) sequence enhances contrast by suppressing signals from cerebrospinal fluid and gray matter, thereby rendering white matter lesions, including the epileptogenic hippocampus, more discernible on the affected side.

期刊介绍: Magnetic Resonance Imaging (MRI) is the first international multidisciplinary journal encompassing physical, life, and clinical science investigations as they relate to the development and use of magnetic resonance imaging. MRI is dedicated to both basic research, technological innovation and applications, providing a single forum for communication among radiologists, physicists, chemists, biochemists, biologists, engineers, internists, pathologists, physiologists, computer scientists, and mathematicians.
