【摘要】：目的探讨3.0 T MR多序列成像评估食管鳞状细胞癌是否侵犯胸主动脉、气管或支气管,以判断肿瘤的可切除性。方法搜集经内镜活检证实的鳞状细胞癌45例,术前均行3.0 T MRI T1WI、脂肪抑制T2WI、动态增强扫描,评价食管鳞状细胞癌与周围结构的解剖关系,并与手术病理结果进行对照。结果 (1)若结合"夹角法"和"三角法"判断胸段食管癌侵犯胸主动脉壁,灵敏度、特异度、准确度高达97.6%、100%、97.8%。用"三角法"判断胸段食管癌侵犯胸主动脉壁,灵敏度、特异度、准确度高达95.2%、100%、95.6%;用"夹角法"判断胸段食管癌侵犯胸主动脉壁,其灵敏度、特异度、准确度分别为100%、0、97.4%。(2)以肿瘤与气管或支气管之间的脂肪间隙消失且其接触长度3 cm为标准来判断食管癌侵犯气管或支气管,灵敏度、特异度、准确度分别为97.6%、100%、97.8%。结论高场强MR多序列成像有助于判断食管鳞状细胞癌是否侵犯胸主动脉、气管或支气管,以判断肿瘤的可切除性。
[Abstract]:Objective to evaluate whether esophageal squamous cell carcinoma (ESCC) invades thoracic aorta, trachea or bronchus by 3.0T Mr multisequence imaging, and to determine the resectability of the tumor. Methods 45 cases of squamous cell carcinoma confirmed by endoscopic biopsy were collected. The anatomic relationship between esophageal squamous cell carcinoma and surrounding structure was evaluated by 3. 0T MRI T1WI, fat suppression T2WI and dynamic contrast enhanced scanning. Results 1) the sensitivity and specificity of thoracic esophageal carcinoma invasion of thoracic aorta were determined by "angle method" and "triangle method". The accuracy is as high as 97.6 / 100 and 97.8.The sensitivity, specificity and accuracy of thoracic esophageal carcinoma invading the thoracic aorta wall are as high as 95.2100.The sensitivity and specificity of thoracic esophageal carcinoma invading the thoracic aorta wall are judged by the "angle of inclusion" method. The accuracy was 100 and 97.4, respectively) the sensitivity and specificity of esophageal cancer invading trachea or bronchus were determined by the criteria of the disappearance of fat gap between tumor and trachea or bronchus and the contact length of 3 cm. Conclusion the high field Mr multisequence imaging is helpful to judge whether esophageal squamous cell carcinoma invades thoracic aorta, trachea or bronchus, so as to determine the resectability of the tumor.
