In this study, we evaluated the scan time and image quality of a serious of gastric T2WI imaging, including conventional TSE with cartesian acquisition (TSE), BLADE-TSE, conventional HASTE sequence and a new TSE corrected HASTE sequence (TSE-HASTE). We found that the HASTE sequences can provide comparable image quality to TSE sequences, while is insensitive to motion and susceptibility artifacts. For patients with poor respiratory movement, HASTE sequence may be used as a good replacement to the TSE sequences, and TSE-HASTE sequence may provide a better image contrast compared to conventional HASTE.
