摘　　要：目的探究双源CT低剂量扫描技术在诊断肠系膜缺血性疾病中的价值。方法回顾性分析我院双源CT不同剂量扫描方案诊断肠系膜缺血性疾病的结果。结果两组患者个性参数(性别比、年龄、BMI)和扫描长度等无明显差异,不具统计学意义(P>0.05);两组患者图像质量的主观评分,诊断一致性较高,无明显差异(P>0.05);观察组患者平均有效辐射剂量为(2.43±0.76)m Sv,对照组平均有效辐射剂量为(4.21±1.33)m Sv,观察组明显低于对照组(P<0.05),差异具有统计学意义。以血管造影检查及手术结果为金标准判断不同剂量扫描方案下影像诊断准确率,两组诊断肠系膜血管性病变准确率为100%。结论双源CT低剂量诊断肠系膜缺血性疾病具有较高的准确性,同时降低了辐射剂量,具有推广价值。Objective To explore the value of dual-source CT low dose scanning technique in the diagnosis of mesenteric ischemic disease.Methods The results of different doses of dual source CT in the diagnosis of mesenteric ischemic disease were retrospectively analyzed.Results There were no significant differences in personality parameters(sex ratio,age,BMI)and scanning length between the two groups(P>0.05).The subjective score of the image quality of the two groups was high,and there was no significant difference between the two groups(P>0.05).The average effective radiation dose was(2.43±0.76)mSv in the control group and(4.21±1.33)mSv in the observation group,The average radiation dose received by the patients in the observation group was significantly lower than that of the control group,the difference was Statistical significance(P<0.05).The accuracy of the two groups was 100%in the diagnosis of mesenteric vascular lesions by angiography and surgical outcome.Conclusion The dual source CT low dose scanning scheme has a high accuracy in the diagnosis of mesenteric ischemic disease and reduces the dose of radiation.It is of great value for popularization.
