Synopsis

Keywords: Digestive, Image ReconstructionHigher resolution and better image quality of 3D FIESTA sequence is used for evaluating bowel inflammation in CD; however, we found 2D SSFSE_DLwith significantly higher SNR and CNR of ileum and terminal ileum than 3D FIESTA and, of course, conventional 2D SSFSE. 2D SSFSE_DL shortened scan time and also offered better image quality than 3D FIESTA in assessment of bowel inflammation in CD. The SSFSE sequence alone has been considered sufficient in lesion detection[2]; SSFSE with DLR has great potential in elevation of detection rate without extra imaging time.
