CT联合MRI对老年多发性急性期脑梗死患者的临床诊断价值

Clinical Value of CT Combined with MRI in Elderly Patients with Multiple Cerebral Infarction

目的探究CT联合MRI对老年多发性急性期脑梗死患者的临床诊断价值。方法选取2017年4月至2018年5月武汉钢铁(集团)公司第二职工医院神经内科收治的75例老年疑似多发性急性期脑梗死患者作为研究对象,均进行CT和MRI检查,评估CT联合MRI的诊断价值。结果CT检查准确率68.0%;MRI检查准确率81.3%(61/75);CT联合MRI检查准确率96.0%(72/75),CT联合MRI准确率明显高于单纯CT或MRI检查,差异具有统计学意义(P<0.05)。CT联合MRI检查对发病24h内、发病24~48h检出率明显高于单纯CT或MRI检查,差异具有统计学意义(P<0.05)。CT灵敏度64.7%、特异度62.9%、阳性预测值45.8%、阴性预测值78.6%,准确率68.0%;MRI灵敏度92.3%、特异度84.6%、阳性预测值75.0%、阴性预测值95.7%,准确率81.3%。结论CT联合MRI对老年多发性急性期脑梗死检出率较高,优于单纯应用CT和MRI检查。

Objective To investigate the clinical value of CT combined with MRI in elderly patients with multiple cerebral infarction.Methods Seventy-five elderly patients with suspected multiple cerebral infarction admitted to the Department of Neurology from April 2017 to May 2018 were enrolled in the study.CT and MRI were performed to evaluate the diagnostic value of CT combined with MRI.Results The accuracy of CT examination was 68.0%;the accuracy of MRI was 81.3%(61/75);the accuracy of CT combined with MRI was 96.0%(72/75);the accuracy of CT combined with MRI was significantly higher than that of CT and MRI alone(P<0.05).The detection rate of CT combined with MRI was significantly higher than that of CT and MRI within 24 hours and 24~48h after onset(P<0.05).CT sensitivity was 64.7%,specificity was 62.9%,positive predictive value was 45.8%,negative predictive value was 78.6%,accuracy was 68.0%;MRI sensitivity was 92.3%,specificity was 84.6%,positive predictive value 75.0%,negative predictive value 95.7%,accuracy 81.3%.Conclusion CT combined with MRI has a higher detection rate in elderly patients with multiple cerebral infarction,better than CT and MRI.
