T1ρ dispersion imaging is an emerging MRI technique for tissue characterization. Multiple independent repetitions of T1ρ experiments at different spin-lock frequencies have to be performed to generate tissue T1ρ dispersion curve. In this work, we demonstrate the feasibility of an integrated imaging and quantification approach for T1ρ dispersion imaging, which allows simultaneous generation of T1ρ maps at multiple spinlock frequencies in one coherent workflow. This opens door for further data undersampling to exploit redundancy at higher dimension data space, further reducing total scan time needed for the time-consuming T1ρ dispersion imaging.
