Retrospective compressive sensing techniques demonstrate promise accelerating acquisition of high-resolution images of the femur while maintaining sufficient image quality to assess fracture risk. While the trabecular bone microstructure was preserved at an undersampling rate of 30%, lower sampling rates of 10% and 5% exhibited visually apparent artifacts and image degradation. Similarly, bone stiffness at 30% resembled fully sampled data but the error increased as sampling rate decreased. Nevertheless, the results show that compressive sensing is a promising candidate for accelerating the acquisition rate, and further prospective studies are needed to further validate this finding.
