摘要

在多发性硬化症(MS)患者中,常规磁共振成像(MRI)显著提高了我们检测脑和脊髓宏观异常的能力,但对脑白质微观的研究很少。对1例多发性硬化症患者的t2加权图像进行不同正常白质MRI单元的纹理分析。本研究旨在探讨多发性硬化症患者脑白质的微观变化。选取感兴趣的脑白质区域,根据单个信号病灶的垂直上下或水平方向分为三组。提取的纹理参数随信号焦点与感兴趣区域的距离而变化。描述了纹理参数模型。

Study on normal appearing white matter of multiple sclerosis by texture analysis and modeling with MRI
In patients with multiple sclerosis (MS), conventional magnetic resonance imaging (MRI) has markedly improved our ability to detect the macroscopic abnormalities of the brain and spinal cord, but brain white matter microcosmic research was few. Texture analysis was performed in different normal appearing white matter MRI unit on T2-weighted images from one patient with multiple sclerosis. The goal of this study was a exploration on microcosmic variety of brain white matter for patient with multiple sclerosis. Each selected brain white matter region of interest was divided into three groups according to vertical up or down or horizontal direction from single signal focus. Each extracted texture parameters was variational following the distance between signal focus and ROI. And texture parameter model was described.
