MRI provides accurate and high-precision body composition measurements. Routinely, data acquisition is performed using system’s integrated body coil, which creates a challenge in terms of scan time and breath-hold duration. This work utilized Compressed Sensing with 2pt Dixon to reduce the acquisition time by 40% without impacting the quantitation of body composition measurements. Variations were found to be small compared to test-retest precision. This provides an opportunity to add MRI based body composition analysis to most MRI examinations with minimal scan time impact without a change in coil or patient setup
