摘　　要：目的观察血管CT成像技术在外伤性脑出血早期诊断及预后评估中的价值。方法选取吉安市第一人民医院2018年10月-2023年9月60例外伤性脑出血患者作为研究对象,按照随机数字表法将所有患者分为对照组和研究组,每组30例。对照组应用常规CT技术检查,研究组应用血管CT成像技术检查。以手术结果为“金标准”,比较两组诊断效能(诊断符合率、灵敏度、特异度、误诊率、漏诊率)、检出率(基底节出血、脑叶出血、丘脑出血、脑干出血)、检查情况(扫描完成时间、图像减影时间、辐射剂量)、图像质量。结果研究组确诊为外伤性脑出血的患者28例,对照组确诊为外伤性脑出血的患者21例。两组诊断特异度、误诊率比较,差异无统计学意义(P>0.05)。研究组诊断符合率、灵敏度高于对照组,且研究组漏诊率低于对照组(P<0.05);研究组检出率高于对照组(P<0.05);研究组扫描完成时间、图像减影时间、辐射剂量低于对照组(P<0.05);研究组图像质量优于对照组(P<0.05)。结论血管CT成像技术在外伤性脑出血早期诊断及预后评估中的应用效果确切,可获取患者清晰影像,准确鉴别患者实际病情,检查速度快,图像质量高,值得应用。Objective To observe the value of vascular CT imaging in early diagnosis and prognosis evaluation of traumatic cerebral hemorrhage.Methods A total of 60 patients with traumatic cerebral hemorrhage from October 2018 to September 2023 in the Ji'an First People's Hospital were selected as the research objects.All patients were divided into control group and study group according to the random number table method,with 30 patients in each group.The control group was examined by conventional CT technology,and the study group was examined by vascular CT imaging technology.Taking the surgical results as the gold standard,the diagnostic efficacy(diagnostic coincidence rate,sensitivity,specificity,misdiagnosis rate,missed diagnosis rate),detection rate(basal ganglia hemorrhage,lobar hemorrhage,thalamus hemorrhage,brainstem hemorrhage),examination situation(scanning completion time,image subtraction time,radiation dose)and image quality were compared between the two groups.Results Totally 28 patients in the study group were diagnosed with traumatic cerebral hemorrhage,and 21 patients in the control group were diagnosed with traumatic cerebral hemorrhage.There was no significant difference in diagnostic specificity and misdiagnosis rate between the two groups(P>0.05).The diagnostic coincidence rate and sensitivity of the study group were higher than those of the control group,and the missed diagnosis rate of the study group was lower than that of the control group(P<0.05).The detection rate of the study group was higher than that of the control group(P<0.05).The scanning completion time,image subtraction time and radiation dose in the study group were lower than those in the control group(P<0.05).The image quality of the study group was better than that of the control group(P<0.05).Conclusion The application of vascular CT imaging technology in the early diagnosis and prognosis evaluation of traumatic cerebral hemorrhage is effective,which can obtain clear images of patients,accurately identify the actual condition of patien
