This study evaluated the length of esophageal cancer lesions after neoadjuvant treatment with MR and thin-layer CT scanning using the length of gross specimens as the gold standard. MR sequence included T2WI and contrast-enhanced StarVibe (DCE StarVibe). In this study, two readers measured the length of esophageal cancer lesions on T2WI, DCE StarVibe and CT images. It was found that contrast-enhanced Starvibe and thin-slice CT can be used to measure the lenth of esophageal cancer after neoadjuvant treatment.
