摘　　要：目的 探讨CT增强与MR增强扫描对腹主动脉及分支血管的显示能力及诊断价值。方法 选择行腹部检查患者47例，入院后均行常规CT增强扫描检查，并于1周内完成MR增强扫描检查。由医院2名具有3年以上工作经验影像诊断医师对患者CT及MR图像进行分析，并测量患者腹主动脉及双侧肾动脉、肠系膜上动脉、腹腔干直径。对比两种成像方式测量数值，并以应用Pearson相关系数对CT增强与MR增强扫描测量数值结果进行线性分析。结果 ①两种成像方法测量数值：CT增强与MR增强扫描成像测量腹主动脉前后径、右肾动脉、左肾动脉、肠系膜上动脉及腹腔干直径比较差异未见统计学意义（P〉0.05）；②两种成像方法测量数值相关性：CT增强与MR增强扫描成像测量腹主动脉前后径、右肾动脉、肠系膜上动脉及腹腔干存在强相关，左肾动脉存在中等程度相关（P〈0.05）。结论 CT增强与MR增强扫描在腹主动脉及其分支血管的诊断中均可获得准确的血管测量数据，且MR增强扫描对人体无电离辐射，具有一定安全性。Objective To investigate the display ability and diagnostic value of CT enhancement and MR enhanced scan in abdominal aorta and branch vessels.Methods Forty-seven patients with abdominal examination underwent routine CT enhancement scan after admission and MR Enhanced scan was completed within 1 week. CT and MR images of the patients were analyzed by two imaging doctors with more than 3 years working experience in hospital. The diameter of abdominal aorta and, bilateral renal artery, superior mesenteric artery and abdominal cavity were measured.The measured values of the two imaging methods were compared, and the Pearson correlation coefficient was used to analyze the numerical results of CT enhancement and MR enhanced scanning.Results ①The two imaging methods： there was no significant difference in the diameter of the abdominal aorta, the right renal artery, the left renal artery, the superior mesenteric artery or the celiac trunk measured by CT enhancement and MR enhanced scan imaging （P〉0.05）. ②Two imaging methods measuring numerical correlation： enhanced CT and enhanced MR scan before and after imaging measurement of abdominal aortic diameter, right renal artery, superior mesenteric artery and celiac was strongly related. The left renal artery had a moderate degree of correlation （P〈0.05）.Conclusions CT enhanced and MR enhanced scan can get accurate vascular measurement data in the diagnosis of abdominal aorta and its branch vessels, and MR enhanced scan is safe for the human body without ionizing radiation.
