The Application of 3T MRI in Esophageal Cancer

It is very significant that assessing TN staging in esophageal cancer patients before surgery, furthermore, determining the optimize surgical strategy, predict the the efficacy of radiotherapy for patients who were not chosen to be surgeried, and define the range of lymph node for radiotherapy. It has been reported that the application of MRI in metastasis of lymph node of other cancer, but not in metastasis lymph node with esophageal cancer. Only a few studies focused on T staging using conventional MRI in esophageal cancer, however, relatively new sequences in the chest deserve widely used. To develop a pre-treatment evaluation methods for TN staging in patient with esophageal cancer by utilization of the new imaging methods (T2-TSE-BLADE, T2 maps, StarVIBE). By analysising the relationship between TN staging and imaging features to find the imaging characteristics for TN staging, and to find the indicators of magnetic resonance imaging new technology and reference values for facilitate pre-treatment diagnosis of lymphnode metastasis, optimize surgical strategy, predict the the efficacy of adjunctive therapy, and OS and define the range of lymph node for radiotherapy, as making personal treatment planning for esophageal cancer.
