| 摘 要： | 目的：本文旨在研究ＭＲＩ、ＣＴ对早期脑动脉硬化诊断价值。材料和方法：对７０例早期脑动脉硬化的患者进行ＭＲＩ、ＣＴ检查。结果：６２例ＭＲＩ检查阳性，Ｔ２ＷＩ发现斑点状高信号２８０个，其中额叶１２１个（４３．２％），顶叶２０个（７．１％），基底节７５个（２６．８％），丘脑２６个（９．３％），脑干１５个（５Ａ％），其它部位２４个（８．６％）。ＣＴ对早期脑动脉硬化的敏感性为１２．５％，定性诊断准确率为９４．３％。ＭＲＩ则分别为１００％和９６．４％，ＭＲＩ对微小病变的显示较ＣＴ更优越。结论：ＭＲＩ应作为早期脑动脉硬化的首选检查方法。

| Abstract: | To deliberate the early diagnosis of cerebral arteriosclerosis with CT and MRI.Materials and Methods:The MRI and CT scans of 70 early stage of cerebral arteriosclerosis cases were comparatively evaluated. Results: 280 patchy hyperintensity lesions of brain were found on T2 WI in 62 cases. These lesions were located in frontal lobes (43.2%), parietal lobes(7.1%),basal ganglia (26.8%), thalamus (9.3%),brainstem (5.4%) and other sites (8.6%). The sensitivity, property determination accuracies of CT and MRI in early stage of cerebral arteriosclerosis were 12.5%,94.3% for the former and 100%, 96.4% respectively for the latter. MRI was more efficient in demonstrating tiny lesions than CT.Conclusion:MRI ought to be the first method of choice for demonstrating the early stage of cerebral arteriosclerosis. |
