目的:探讨术前CT及MRI检查判断食管癌外侵主动脉的价值。方法:32例经病理学检查确诊的食管癌患者行术前CT检查,其中14例行MRI胸部检查,以脂肪三角的消失、肿物与主动脉相接触的弓>45°且二者间脂肪间隙消失为主动脉受侵判断标准。将CT及MRI检查诊断结果与手术及术后病理学结果对比分析。结果:本组32例CT检查食管癌外侵主动脉的敏感性、特异性及准确性分别为75.00%、87.50%及84.36%;14例MRI检查的敏感性、特异性及准确性分别为80.00%、88.89%及85.71%。CT与MRI检查敏感性、特异性及准确性均较高,且2者间差异无统计学意义。结论:CT与MRI判断食管癌外侵主动脉均有很大价值。
Objective: To evaluate the value of preoperative CT and MRI in detecting the invasion of esophageal cancer to the aorta. Methods: Thirty-two patients with esophageal cancer diagnosed by pathology underwent preoperative CT examination. Among them, 14 patients underwent MRI chest examinations. Their fatty trigones disappeared and the tumor contacted the aorta with a bow> 45 °. The fat between the two Disappearance of the gap as aortic invasion criterion. Comparing the results of CT and MRI examination with the results of surgery and postoperative pathology. Results: The sensitivity, specificity and accuracy of 32 cases of esophageal cancer invaded aorta were 75.00%, 87.50% and 84.36%, respectively. The sensitivity, specificity and accuracy of MRI in 14 cases were 80.00 %, 88.89% and 85.71% respectively. The sensitivity, specificity and accuracy of CT and MRI examination were high, and there was no significant difference between the two. Conclusion: CT and MRI are very valuable in determining the invasion of esophageal cancer to the aorta.
