摘　　要：目的旨在探讨CT联合磁共振(MRI)检查对不同发病时间脑梗死患者的诊断效果。方法对2017年12月至2019年1月于我院就诊治疗的76例脑梗死患者的临床及影像学资料进行回顾性分析,以病理检查结果为“金标准”,总结不同检查方法对于不同脑梗死的检出诊断率及图像表现。结果CT联合MRI检查对脑梗死的诊断率显著高于CT检查,比较差异有统计学意义(P<0.05);CT联合MRI检查对不同发病时间脑梗死的诊断率均显著高于CT检查,比较差异具有统计学意义(P<0.05)。早期脑梗死CT和MRI形态、结构基本类似,可见脑沟裂池消失或模糊低密度区,随着发病时间的延长,CT可出现岛带征和脑动脉高密度征,而MRI则表现为T1WI低信号,病灶于T2WI及FLATR均为高信号。结论CT和MRI检查均可对不同时期脑梗死的病理变化清晰显示,但CT联合MRI检查可明显提高脑梗死的诊断率,值得临床使用。Objective To investigate the diagnostic effect of CT combined with magnetic resonance imaging(MRI)on patients with cerebral infarction at different onset times.Methods The clinical and imaging data of 76 patients with cerebral infarction treated in our hospital from December 2017 to January 2019 were retrospectively analyzed.The results of the pathological examination were used as criteria to summarize the detection rate and image performance of different examination methods for different cerebral infarctions.Results The diagnostic rate of CT combined with MRI for cerebral infarctions was significantly higher than that of CT examination.The difference was statistically significant(P<0.05).The diagnostic rate of CT combined with MRI for cerebral infarctions at different onset times was significantly higher than that of CT examination.The difference was statistically significant(P<0.05).The shape and structure of early cerebral infarction in CT and MRI were similar.It can be seen that the sulcus and cistern disappeared,or there was a blurred low-density area.With the prolongation of onset time,CT can show insular ribbon signs and high density of cerebral arteries,while MRI showed T1WI low signal,and the lesions showed high signal in T2WI and FLATR.Conclusion CT and MRI examinations can clearly show the pathological changes of cerebral infarction in different periods,but CT combined with MRI can significantly improve the diagnosis rate for cerebral infarction.It is worthy of clinical use.
