Abstract:
Objective To compare the image quality of readout-segmented diffusion weighted imaging(RESOLVE-DWI)and integrated slice-by-slice shimming diffusion weighted imaging(iShim-DWI)in patients with nasopharyngeal carcinoma.Methods A retrospective study was conducted on 26 patients with nasopharyngeal carcinoma confirmed by pathology.The imaging data included RESOLVE-DWI and iShim-DWI.The signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of the two sequences were compared by one deputy chief imaging technician.And two experienced radiologists used the 5-point scoring scheme to compare the lesion clarity,image artifacts,and antideformation ability of the two sequences,repectively.Results The SNR and CNR of the iShim-DWI sequence were significantly higher than those of RESOLVE-DWI sequence(P＜0.01).While the subjective scores of lesion clarity,image artifacts,and antideformation ability on RESOLVE-DWI were significantly better than those of iShim-DWI,and the differences were statistically significant(P＜0.01).Conclusion Both RESOLVE-DWI and iShim-DWI obtained good images.With sufficient SNR and CNR,RESOLVE-DWI has clearer lesions and surrounding structures,higher image resolution,fewer artifacts,and better antideformation ability,thus providing clinical advantages in evaluating patients with good physical tolerance.
