Abstract: Objective To investigate the strengths and weaknesses of SPAIR and WE in iShim-IVIM of breast gland MRI scanning. Methods Twenty patients with breast tumor underwent iShim-IVIM and DCE-MRI scanning by SPAIR and WE technology. SNR ,CNR and ADC of the SPAIR-iShim and WE-iShim imaging were cal-culated and imaging quality were evaluated. Statistical analysis was done afterwards. Results The SNR and CNR of WE technology is higher than those of SPAIR statistically (P<0.05). There is no significant statistical differ-ence in score of the images between SPAIR and WE(P>0.05). The ADC of the center of the tumor has no signifi-cant statistical difference between SPAIR and WE(P>0.05). Conclusion The quality of the images using WE is significantly improved than SPAIR ,but both of them can meet the diagnostic requirements ,and the ADC has no statistical difference as well.
