目的 研究CT与MRI在脑梗塞早 期临床诊断中的价值。方法 回顾性分析 2014年2月至2015年3月神经内科确诊的 110例脑梗塞患者的临床资料，患者均 同时接受MRI和CT检查，对比两种检查方 法的诊断结果。结果 MRI的脑梗塞检出 率(93.64%)高于CT(62.73%)，P＜0.05； MRI在不同梗塞部位脑梗塞的检出率均高 于CT，P＜0.05；上述差异均有统计学 意义。病灶形状多为条索状、椭圆及圆 形，其中以圆形病灶最多(63.64%)，直径 ≤5mm的病灶约68.01%，MRI图像更清晰。 结论 MRI及CT均为重要的脑梗塞诊断手 段，于早期脑梗塞而言，前者总检出率、 梗塞部位检出率更高，能清晰反应病灶位 置、大小、形状等，其临床应用价值更 高。

Objective To explore clinical value of CT and MRI in the diagnosis of early cerebral infarction. Methods Clinical data of 110 patients with cerebral infarction confirmed by Neurology Department of the Hospital from February 2014 to March 2015 were retrospectively analyzed, all the patients retrospective analysis received MRI and CT examinations, and diagnosis results of two inspection methods were compared.Results The detection rate of MRI on cerebral infarction (93.64%) was higher than that of CT (62.73%), P<0.05, The detection rates of MRI on cerebral infarction at different infarction positions were higher than such indexes of CT (P＜0.05). These differences were statistically significant. Most of lesion shapes were in funicular, elliptical and circular, the number of ircular lesions (63.64%) were the most, the lesions with diameter ≤5mm approximately hit 68.01%, and their MRI images were clearer. Conclusion MRI and CT are important means of diagnosis on cerebral infarction, general detection rate and infarct detection rate of the former on early cerebral infarction was higher, it can clearly reflect the location, size and shape of lesion, and it delivers higher clinical value.
