This study evaluated the effects of chemical shift fat saturation (FS), Dixon and BLADE techniques to image quality in high-resolution imaging of esophageal cancer using a two-dimensional turbo spin echo (TSE) sequence. After quantitative and subjective quality comparing, TSE-T2WI-CS got higher image quality than T2WI Dixon and T2WI BLADE sequences, which demonstrated certain advantages in the diagnosis of esophageal cancer, while T2WI Dixon and T2WI BLADE sequences also has some advantages respectively.
