Thirteen patients affected with advanced epidermoid carcinoma of the thoracic esophagus were examined by means of CT, MR and endoscopic US (EUS) before and after chemotherapy. Eleven patients underwent esophagectomy and esophagogastroplasty. An intraesophageal prosthesis was positioned in 2 patients since chemotherapy had not modified tumour stage. Post-chemotherapy CT, MR and EUS parameters were compared with the corresponding pathologic findings. As for MR imaging, post-chemotherapy signal intensity variations in T1 and T2 sequences were also evaluated. MR imaging was more accurate than CT in depicting the involvement of mediastinal fatty layers, the relationships between mass and cardiovascular structures, and the cellularity. CT and MR exhibited limitations in identifying metastatic mediastinal lymph nodes, in which case EUS proved to be the most accurate technique. Both CT and MR failed to satisfactorily assess the infiltration of tracheobronchial tree, which was best demonstrated by endoscopy.
对13例晚期胸段食管表皮样癌患者在化疗前后进行了CT、MR和内镜超声（EUS）检查。11例患者接受了食管切除术和食管胃成形术。2例患者因化疗未改变肿瘤分期而置入了食管内假体。将化疗后的CT、MR和EUS参数与相应的病理结果进行了比较。至于MR成像，还评估了化疗后T1和T2序列中的信号强度变化。在描绘纵隔脂肪层受累情况、肿块与心血管结构之间的关系以及细胞密度方面，MR成像比CT更准确。CT和MR在识别纵隔转移性淋巴结方面存在局限性，在这种情况下EUS被证明是最准确的技术。CT和MR都未能令人满意地评估气管支气管树的浸润情况，而这在内镜检查中显示得最好。
