A novel pulse sequence (TWIST DIXON)which combines k-space data sharing strategy used in Time-resolved angiography With Stochastic Trajectories (TWIST) with fat and water separation by dual-echo DIXON was evaluated for breast DCE MRI application. In this study, we compared the image quality of TWIST DIXON sequence with the conventional method of fat suppressed 3D spoiled gradient echo sequence in a group of clinical patients. The results demonstrate that TWIST DIXON technique provides significantly higher perceived SNR, more accurate fat suppression and overall better image quality.
