Esophageal cancer ranks seventh in terms of incidence and sixth in mortality among all cancers. Accurate staging of esophageal cancer helps to choose appropriate therapeutic strategy. Current imaging modalities used for evaluating esophageal cancer have their own disadvantages. Therefore, we compared MRI, which is non-invasive, non-radiating and of high soft-tissue resolution, with EUS in preoperative T staging and with PET/CT in preoperative lymphatic metastases of esophageal cancer. In this study, MRI showed higher sensitivity, specificity and accuracy in T staging, while MRI and PET/CT showed similar performance in lymph nodes evaluation.
