MSCT、MRI检查诊断老年人腔隙性脑梗塞的对比分析

Comparison and Analysis of MSCT and MRI in the Diagnosis of Lacunar Infarction in the Elderly

目的探讨MSCT和MRI检查诊断老年人腔隙性脑梗塞的效果。方法选取2018年2月至2019年3月在我院确症为腔隙性脑梗塞患者的临床资料78例,将MSCT检查和MRI检查的诊断结果进行讨论和分析,分析两种方法中腔隙性脑梗塞的不同影像学表现,对比两种检查下疾病诊断确诊率和病灶检出率。结果 MRI检查下共诊断出75例腔隙性脑梗塞,疾病诊断正确率为96.15%;MSCT共诊断出52例腔隙性脑梗塞,疾病诊断正确率为66.66%,明显低于MRI检查(P<0.05)。78例病人手术中共检出梗死病灶为350个,以此对照,MRI检查出病灶330个,MSCT检查出290个,MRI的检出率为94.28%,明显高于MSCT检出率(82.85%),差异有统计学意义(P<0.05)。结论 MSCT、MRI均为检查诊断老年人腔隙性脑梗塞的有效手段,但是MRI对于早期腔隙性脑梗塞诊断效果更佳。

Objective To investigate the effect of MSCT and MRI in the diagnosis of lacunar infarction in the elderly.Methods The clinical data of 78 patients with lacunar infarction diagnosed in our hospital from February 2018 to March 2019 were selected.The diagnosis results of MSCT and MRI were discussed and analyzed.The different imaging featu res of lacunar infarction in the two methods were analyzed,and the diagnosis rate and lesion detection rate of the two methods were compared.Results 75 cases with lacunar infarction were diagnosed by MRI.The correct rate of diagnosis was 96.15%.52 patients with lacunar infarction were diagnosed with MSCT.The diagnostic accracy rate was 66.66%,which was significantly lower than that of MRI(P<0.05).350 infarct lesions were detected in 78 patients.330 lesions were detected by MRI,and 290 lesions were detected by MSCT.The detection rate of MRI was 94.28%,which was significantly higher than that of MSCT,82.85%.The difference was statistically significant(P<0.05).Conclusion MSCT and MRI are effective methods for the diagnosis of lacunar infa rction in the elderly,but MRI is more effective in diagnosing early lacunar infarction.
