摘要
目的探讨多层螺旋CT联合MRI对脑梗死合并脑出血患者的诊断价值。方法选取83例疑似脑梗死并脑出血患者为研究对象,以临床观察和综合检查为“金标准”,比较CT和MRI的检出率,并计算CT与MRI联合诊断的敏感度、特异度及准确度。结果金标准确诊脑梗死合并脑出血68例,单纯脑出血8例,单纯脑梗死7例。CT检查确诊脑梗死合并脑出血49例,单纯脑梗死或脑出血11例,灵敏度、特异度、准确度分别为72.06%、73.33%、72.29%。MRI检查确诊脑梗死合并脑出血53例,确诊单纯脑梗死或脑出血12例,灵敏度、特异度、准确度分别为77.94%、80.00%、78.31%。CT联合MRI诊断灵敏度、准确度分别为94.12%、91.57%,均高于单独CT、MRI检查,差异有统计学意义(P<0.05);CT联合MRI诊断特异度为80.00%,与单独CT、MRI检查比较,差异无统计学意义(P>0.05)。结论多层螺旋CT联合MRI对脑梗死并脑出血诊断敏感度和准确度较高,可为临床诊断与治疗提供依据。
Objective To explore the diagnostic value of multi-slice spiral CT combined with MRI in patients with cerebral infarction and cerebral hemorrhage.Methods A total of 83 patients with suspected cerebral infarction and cerebral hemorrhage were selected as study subjects.Clinical observation and comprehensive examination were used as the"gold standard"to compare the detection rate of CT and MRI,and sensitivity,specificity and accuracy of combined diagnosis of CT and MRI were calculated.Results Sixty-eight cases of cerebral infarction complicated with cerebral hemorrhage,8 cases of cerebral hemorrhage alone and 7 cases of cerebral infarction were confirmed by gold standard.CT examinations confirmed 49 cases of cerebral infarction complicated with cerebral hemorrhage,and 11 cases of simple cerebral infarction or cerebral hemorrhage.The sensitivity,specificity and accuracy were 72.06%,73.33%and 72.29%,respectively.MRI examination confirmed 53 cases of cerebral infarction complicated with cerebral hemorrhage,and 12 cases of simple cerebral infarction or cerebral hemorrhage.The sensitivity,specificity and accuracy were 77.94%,80.00%and 78.31%,respectively.The diagnostic sensitivity and accuracy of CT combined with MRI were 94.12%and 91.57%,respectively,which were significantly higher than that of single detection of CT or MRI(P<0.05);the diagnostic specificity of CT combined with MRI was 80.00%,and the difference was not statistically significant compared with single detection of CT or MRI(P>0.05).Conclusion Multi-slice spiral CT combined with MRI has higher sensitivity and accuracy in the diagnosis of cerebral infarction and cerebral hemorrhage,which can provide basis for clinical diagnosis and treatment.
