CT和MRI对早期腔隙性脑梗死的诊断价值对比

Comparison the diagnostic value of CT and MRI on early lacunar cerebral infarction

目的探讨并对比CT和MRI对早期腔隙性脑梗死的诊断价值。方法回顾性分析我院2016年2月至2016年12月收治的46例早期腔隙性脑梗死患者的临床资料,所有患者接受CT和MRI检查。比较两种检查方法对早期腔隙性脑梗死的检出阳性率;记录两种检查方法发现病灶的数目、大小、部位;比较两种检查方法的小病灶检出率。结果 46例早期腔隙性脑梗死患者经MRI检查的阳性率为97.83%(45/46),高于CT检查的80.43%(37/46)(P<0.05);MRI检查病灶数309个,大小为1.5~14.0 mm,CT检查病灶数138个,大小为4.0~16.0 mm;MRI检查的小病灶检出率为34.95%,高于CT检查的4.35%(P<0.05)。结论 MRI诊断早期腔隙性脑梗死准确性高于CT,能够检出更多病灶并清晰显示小病灶,具有较高的临床应用价值。

Objective To explore and compare the diagnoslic value of CT and MRI on early lacunar cerebral infarclion. Methods The clinical data of 46 cases of palienls with early lacunar cerebral infarction in our hospilal from February 2016 lo December 2016 was relrospeclively analyzed. All lhe palienls were examined by CT and MRI, lhe posilive deleclion rale of early lacunar infarclion was compared between lhe lwo methods; lhe number, size and location of lhe lesions were recorded of lhe lwo methods; lhe deleclion rale of small lesions was compared between lhe lwo methods. Results The posilive deleclion rale examined by MRI in 46 palienls with early lacunar infarclion was 97.83% （45/46）, which was higher lhan 80.43%（37/46）ofCT （ P〈0.05）.ThenumberoflesionsexaminedbyMRIwas 309, andlhesizewas1.5？14.0mm;lhe numberoflesionsexaminedofCTwas138,andlhesizewas4.0？16.0mm.ThedeleclionraleofsmalllesionsbyMRIwas 34.95%, which was higher than 4.35% by CT （ P〈0.05）. Conclusion The accuracy of MRI in lhe diagnosis of early lacunar cerebral infarclion is higher than lhal of CT, il can check oul more lesions and clearly show lhe small lesions, which has high clinical value.
