On low field system, Dixon technique is preferred for its robustness and reliability on T1 weighted imaging. However, for T2/PD weighted imaging, TSE based Dixon suffers from a sever artifacts due to system limitations of low-field scanner. In this abstract, origin of the artifacts is analyzed. An optimized TSE Dixon acquisition scheme is also proposed. A clinical acceptable PD/T2 weighted water/fat separation result is therefore feasible on low-field scanner.
