【摘要】 目的：作者对40例皮层脑梗塞的磁共振表现特点进行了分析。材料与方法：40例中男24例，女16例。年龄45至78岁，平均60、7岁。结果；磁共振检查40例均能清楚显示皮层梗塞的存在，其中27例累及皮层，13例同时累及皮层下。梗塞区域具有长T1长T2信号特点，以T2加权像显示梗塞形态及范围最好，是高信号。单纯累及皮层岩是脑回样，而同时累及皮层下白质者呈三角形或扇形。合并有出血者T1加权病变区皮层内可见细线样高信号。增强扫描呈脑回样强化。结论：作者认为磁共振是诊断皮层脑梗塞最敏感的检查方法。并对鉴别诊断进行了讨论。更多还原

【Abstract】 Purpose: To analyze the MRI finding of cerebral cortex infarction. Material and methods:Forty cerebral cortex infarctionverified by clinic were analyzed. In forty cases that include 24 male and 16 female patients, their ages ranged from 45 to 78 (mean 60. 7years). Results: The presence of cerebral cortex infarction can be revealed distinctively by MR examination in all of the cases; the cortex was involved only in 27 cases, and in other 13 cases the lesion involved deeply with the subcortex. The area of infarction had the nature of long T, and long T, values. The T, weighted images, in which the cortex was presented as high signals, displayed the morphology and region best. The lesion that simply involved with cortex appeared as gyri- like. The lesion that not only involved with cortex but also subcortex white matter appeared as triangular or fan shape. Some cases were associated with hemorrhage. It can be seen in T1 weighted were associated with the high signal lesion area to be shown in thread like pattern. In images enhanced by Gd-DTPA, the lesion area appeared as gyri-like Conclusion: The most sensitive examination method to diagnosis the cortexinfarction was by MR imaging. In addition, a discussion about the differentiation was given in the paper.更多还原
