CT影像诊断高血压脑出血的效果

Effect of CT imaging in the diagnosis of hypertensive cerebral hemorrhage

目的探讨CT影像诊断高血压脑出血的效果。方法选取2017年5月15日~2018年5月15日我院收治的75例疑似高血压脑出血患者作为观察组,另选取同期我院的75例健康体检者作为对照组,均实施CT影像检查,比较两组受检者的血流量(BF)、血容量(BV)、表面通透性(PS)等血流信号指标,分析CT影像诊断判定出血部位的诊断正确率和诊断价值。结果观察组的BF[(23.96±5.71)ml/(100 g·min)]、BV[(0.52±0.13)ml/100 g]、PS[(0.56±0.09)ml/100 g]血流信号低于对照组[(61.23±9.56)ml/(100 g·min)、(2.56±0.42)ml/100 g、(14.56±2.74)ml/100 g](P<0.05);CT影像对丘脑出血诊断的正确率为95.24%,对外囊区出血诊断的正确率为87.50%,对内囊区出血诊断的正确率为100.00%,对壳核区出血诊断的正确率为94.74%,对小脑出血诊断的正确率为100.00%,同时CT影像诊断高血压脑出血的敏感度为95.16%,特异度为92.31%,漏诊率为4.84%,误诊率为7.69%。结论在诊断高血压脑出血时应用CT影像具有较高的诊断正确率。

Objective To explore the effect of computer tomography(CT)imaging in the diagnosis of hypertensive cerebral hemorrhage.Methods A total of 75 patients with suspected hypertensive cerebral hemorrhage admitted to our hospital from May 15,2017 to May 15,2018 were selected as the observation group,and 75 healthy participants for physical examinations in our hospital during the same period were selected as the control group.They were performed with CT examinations.The blood flow signal indicators such as blood flow(BF),blood volume(BV),permeability surface(PS)of the two groups were compared in order to evaluate the diagnostic accuracy of CT imaging diagnosis in determining the bleeding site and its diagnostic value.Results The blood flow signals such as BF,BV,and PS of the observation group were(23.96±5.71)ml/(100 g·min),(0.52±0.13)ml/100 g,and(0.56±0.09)ml/100 g,which were lower than those of the control group,(61.23±9.56)ml/(100 g·min),(2.56±0.42)ml/100 g,and(14.56±2.74)ml/100 g,respectively(P<0.05).The accuracy rate of CT imaging in diagnosis of thalamic hemorrhage was 95.24%,that of hemorrhage of capsula externa was 87.50%,that of hemorrhage of capsula interna was 100.00%,that of hemorrhage of putamen was 94.74%,and that of hemorrhage of cerebellum area was 100.00%.The sensitivity,specificity,missed diagnosis rate,and misdiagnosis rate of CT diagnosis for hypertensive cerebral hemorrhage were 95.16%,92.31%,4.84%and 7.69%.Conclusion In the diagnosis of hypertensive cerebral hemorrhage,the use of CT imaging has a high diagnostic accuracy.
