Magnetic resonance imaging (MRI) of the hip joint requires high-spatial resolution and signal-to-noise ratio (SNR), which results in long scan times. Compressed sensing (CS) reconstruction approaches are currently used in research to achieve very large accelerations for advanced MR studies. We explored the feasibility of using CS to achieve moderate acceleration factors in routine hip imaging, while maintaining diagnostic quality. Our results suggest that it could be possible to accelerate 2D turbo spin echo acquisitions by a factor of 4 using CS and that 6-fold acceleration is also feasible for T2 mapping based on multi spin echo time-series.
