AbstractMono-exponential T1ρ mapping requires 4 or 5 T1ρ-weighted images with different spin lock times (TSLs) to obtain the T1ρ maps, while bi-exponential T1ρ mapping requires a larger number of TSLs, which further prolongs the acquisition time. In this work, we develop a variable acceleration rate undersampling strategy to reduce the total scan time. A signal compensation strategy with low-rank plus sparse model was used to reconstruct the T1ρ-weighted images. We provide the reconstructed images and the estimated T1ρ maps at an acceleration factor up to 6.1 in fast bi-exponential T1ρ mapping.
