Summary

Accurate staging is critical for effective gastric cancer treatment planning. Conventional DWI (C-DWI) has limitations in image quality due to magnetic field inhomogeneity, which hampers precise T staging.

This study aims to compare the image quality and T staging accuracy of C-DWI, TSE-DWI, and ZOOMit-DWI (Z-DWI) sequences in MRI examinations of gastric cancer patients.

A prospective study plan to enroll 72 gastric cancer patients undergoing preoperative MRI with C-DWI, TSE-DWI, and Z-DWI sequences using a 3.0 T scanner. Quantitative metrics (ADC, SNR, CNR) and image quality were evaluated. T staging accuracy was assessed by comparing MRI results with postoperative pathological staging using ROC analysis.

Scanning parameter

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.
