Body MRI protocols at 3T are often lengthy due to decreased duty cycle, high SAR, and general inefficiencies of the sequences used. This study (n=22) assessed a new sequence, 2-point mDIXON (mDIXON), which, like the original DIXON, can provide in-phase (IP), out-of-phase (OP), water, and fat images with increased duty cycle and better image quality compared to existing methods. New mDIXON is a more efficient alternative and can replace the existing 2D IP and OP as well as gadolinium-enhanced 3D T1-weighted (eTHRIVE) sequences. The new strategy based on mDIXON will lead to much shorter body MRI exam times at 3T.
