The proposed method can accurately reconstruct the $$$T_{1\rho}$$$-weighted image series and $$$R_{1\rho}$$$ dispersion from highly undersampled k-space data, and thereby significantly reduce the scan time of $$$T_{1\rho}$$$ imaging.

Figure 2. The reconstructed $$$T_{1\rho}$$$-weighted images at $$$TSL=40$$$ ms with locking field amplitude w=5000 Hz using the SCOPE method and the L+S method for net acceleration factor R=3 and 4, respectively.
