CT与MRI对腔隙性脑梗死的诊断临床分析

Clinical Analysis of CT and MRI Diagnosis of Lacunar Infarction

目的分析CT与MRI对腔隙性脑梗死的诊断价值。方法方便选择该院自2015年1月—2017年11月收治的126例确诊为腔隙性脑梗死的患者,均做头颅CT及MRI,对比2种检查方法结果。结果 MRI小病灶检出率为34.46%(234/679)明显高于CT检出率2.32%(6/259),相对比,差异有统计学意义(χ2=8.498 3,P<0.05)。MRI额叶病灶检出率为39.62%明显高于CT检出率7.72%,内囊检出率为4.71%明显低于CT检出率33.98%,相对比,差异有统计学意义(χ2=8.398 9,6.874 2,P<0.05)。两种检查方法所需费用及检查时间对比,MRI相对较高,差异有统计学意义(P<0.05);MRI检查所需时间为(21.09±4.87)min,所需费用为(1 103.48±7.86)元。结论采用MRI可在早期检测出腔隙性脑梗死,且有较高的确诊率,值得应用。

Objective This paper tries to analyze the CT and MRI diagnosis of lacunar infarction.Methods 126 patients diagnosed as lacunar infarction in this hospital from January 2015 to November 2017 were examined by CT and MRI respectively.The results of two methods were compared.Results The detection rate of small lesions in MRI was 34.46%(234/679),significantly higher than that of CT 2.32%,(6/259),the difference was statistically significant(χ2=8.498 3,P<0.05).The detection rate of frontal lobe MRI was 39.62%,significantly higher than the CT detection rate of 7.72%,MRIIA capsule detection rate of 4.71%was significantly lower than the CT detection rate of 33.98%,the relative ratio were significantly different,the difference was statistically significant(χ2=8.398 9,6.874 2,P<0.05);comparison of cost and examination time between the two methods of examination,the MRI was relatively high,and the difference was statistically significant(P<0.05).MRI examination time(21.09±4.87)min,the required cost of(1 103.48±7.86)yuan.Conclusion The use of MRI in the early detection of lacunar infarction,and a high rate of diagnosis,it is worth application.
