Study on the Value of Three DWI Scanning Sequences in Staging of Gastric Cancer

Based on abdominal scanning, TSE-DWI,ZOOMIT DWI and EPI-DWI scans were performed, and the study was divided into two steps according to the nanomotion criteria. The first step was self-controlled, which was divided into experimental group and control group. The experimental group included TSE-DWI,ZOOMit DWI, and the control group included EPI-DWI. Then the image quality was evaluated by subjective and objective evaluation indexes. In the second step, the three DWI stages were performed separately by four diagnosticians, with an interval of 1 month, and statistical analysis was performed at the end.
