Esophageal carcinoma is the eighth most common cancer worldwide with a rising incidence. It has been demonstrated that the normal esophageal wall can be depicted as eight layers in T2 weighted MRI , however only qualitative assessment has been made so far. In this work, an ex vivo experiment was conducted on 3.0T clinical scanner to prospectively establish the quantitative T2 value as a means of depicting the normal esophageal wall by T2-mapping and evaluate the depth of the carcinoma invasion using histopathological as a reference.
