摘　　要：目的:评估CT血管成像技术(CT Angiography,CTA)与常规CT平扫在脑出血早期诊断以及病因诊断中的应用价值,并对比两种方法对活动性脑出血的诊断价值。方法:回顾性分析本院神经外科在2021年2月-2023年2月收诊的102例脑出血患者的病例资料,所有患者均接受CT平扫和CTA检查,记录两种方法对脑出血病灶的检出率、病因诊断符合率以及活动性脑出血的预测价值。结果:CTA对脑出血的早期检出率96.08%,显著高于CT平扫的早期检出率81.37%,差异有统计学意义(P<0.05);在脑动脉瘤、血管畸形、烟雾病、高血压脑出血的病因诊断符合率,CTA均高于CT平扫,差异均有统计学意义(P<0.05);CTA与CT平扫对血肿病灶部位以及病灶形态的检出率差异均无统计学意义(P>0.05);此外,CT平扫的混合征与CTA的斑点征联合使用,对活动性脑出血的诊断灵敏度、准确率均显著高于单一使用任一征象(P<0.05)。结论:CTA在脑出血早期诊断中应用价值高,与常规CT平扫相比,CTA对脑出血的早期诊断有更高的检出率,且有助于检出活动性出血,将CTA与常规CT平扫联合应用能早期发现活动性出血,从而为临床治疗提供可靠信息。Objective:To analyze the application value of CT angiograpghy(CTA)in the early diagnosis of cerebral hemorrhage.Methods:Select the hospital neurosurgery department from February 2021 to February 2023,the object of 102 patients with cerebral hemorrhage,CT scan and CTA,recording the detection rate of cerebral hemorrhage lesions,the diagnosis of diagnosis of CT and CTA diagnostic accuracy,sensitivity and specificity of active bleeding.Results:The early detection rate of CTA was 96.08%higher than that of CT scan,which was 81.37%.,and the difference was statistically significant(P<0.05).In addition,the diagnosis rate of cerebral arteriovenous malformation,cerebral aneurysm,hypertension with arteriosclerosis,and other causes of cerebral hemorrhage,CTA were higher than that of CT scan,and the differences were all statistically significant(P<0.05).There was no significant difference in the detection rate of hematoma location and morphology between CTA and CT scan(P>0.05).Moreover,the diagnostic accuracy and sensitivity of the combined spot and mixed features were higher than those of either sign alone(P<0.05).Conclusion:Vascular CT imaging has high diagnostic value in the early diagnosis of cerebral hemorrhage,which is helpful to clarify the etiology of bleeding early.At the same time,combining it with the mixed sign of conventional CT plain scan can improve the predictive value of active bleeding and guide clinical treatment.
