近来,在薄层矢状面,快速液体衰减翻转恢复(FLAIR)MRI上发现“室管膜下条纹状改变”可用于评估早期多发性硬化(MS)。当病灶1mm厚时可被确认,其方向垂直于(而非平行)室管膜。作者旨在比较MS与非MS病人室管膜下条纹状改变的敏感度和特异度。 所有成像均用1.5T MR设备。在头颅常规MR检查的基础上行薄层矢状面,快速FLAIR成像。头颅常规MRI包括矢状位T_1WI、PDWI和横断面T_2WI。两种研究矩阵192×256,视野>22cm,层厚5mm,间隔1mm。常规SE成像的确切参数如下:500ms/15ms(TR/TE)和3000/30和80,T_1WI两次
Recently, “subependymal streak changes” on thin layer sagittal, fast fluid decay recovery (FLAIR) MRI were found to be useful in the assessment of early multiple sclerosis (MS). When the lesion 1mm thick can be confirmed, its direction perpendicular to (but not parallel) ependymal. The aim of the authors was to compare the sensitivity and specificity of the striated changes in the subventricular zone of MS and non-MS patients. All imaging uses a 1.5T MR device. Thin-layer sagittal, fast FLAIR imaging was performed on the basis of routine craniofacial MR examination. Conventional cranial MRI includes sagittal T_1WI, PDWI and cross-sectional T_2WI. Two research matrix 192 × 256, field of view> 22cm, layer thickness 5mm, spacing 1mm. The exact parameters of conventional SE imaging are as follows: 500ms / 15ms (TR / TE) and 3000/30 and 80, T_1 WI twice
