摘　　要：目的分析对于脑梗死并脑出血的临床诊断应用磁共振成像(MRI)与CT检查的临床效果以及其临床应用价值。方法随机抽取2018年2月—2020年2月该院收治的初诊疑似为脑梗死并脑出血患者76例的临床资料进行回顾性分析,所有患者均接受CT检查和MRI检查,并以临床医师综合诊断结果做为“金标准”,比较CT及MRI检查的诊断符合情况,计算两种检查方式以及二者联合检查时对此病的诊断特异性、敏感性及准确性。结果MRI检查对于脑梗死并脑出血的一次检出率为83.54%,明显高于CT检查一次检出率63.49%,差异有统计学意义(χ^(2)=5.800,P=0.016)。MRI检查检出脑梗死灶共计250个,出血部位共计124个;CT检查检出的脑梗死灶共计197个,出血部位共计87个。CT与MRI联合检查时的特异性、敏感性及准确性分别为92.31%、98.41%和97.37%,均高于单独应用CT或是MRI检查。结论对脑梗死并脑出血患者而言,临床诊断时应用CT与MRI联合检查的诊断准确性更好,能够准确地对梗死灶以及出血灶进行检出,为临床诊治提供较为可靠的影像学依据。Objective To analyze the clinical effect and clinical application value of magnetic resonance imaging(MRI)and CT examination for the clinical diagnosis of cerebral infarction complicated with cerebral hemorrhage.Methods The clinical data of 76 patients with suspected cerebral infarction and cerebral hemorrhage admitted to the hospital during the period from February 2018 to February 2020 were randomly selected for retrospective analysis.All patients underwent CT examination and MRI examination.The comprehensive diagnostic results of physicians are used as the"gold standard"to compare the diagnostic compliance of CT and MRI examinations,to calculate the diagnostic specificity,sensitivity and accuracy of the two examination methods and their combined examinations.Results The detection rate of cerebral infarction complicated with cerebral hemorrhage by MRI examination was 83.54%,which was significantly higher than that of CT examination 63.49%,and the difference was statistically significant(χ^(2)=5.800,P=0.016).A total of 250 cerebral infarcts and 124 bleeding sites were detected by MRI,and 197 cerebral infarctions and 87 bleeding sites were detected by CT examination.The specificity,sensitivity and accuracy of combined CT and MRI were 92.31%,98.41% and 97.37%,respectively,which were higher than those of CT or MRI alone.Conclusion For patients with cerebral infarction and cerebral hemorrhage,the combined examination of CT and MRI examination has better diagnostic accuracy,and can accurately detect infarction and hemorrhage,which provides a more reliable imaging basis for clinical diagnosis and treatment.
