Quantitative T_1ρ MRI provides valuable information on compositional changes in cartilage, but requires longer scan time compared to conventional imaging. In this work, kernel-based low-rank compressed sensing reconstruction was used to accelerate T_1ρ imaging and the retrospective and prospective undersampled results from four subjects were compared to reference T_1ρ values.
