Acquire whole-brain amide CEST mapping at 3T MRI by using steady-state radial sampling CEST with PROPELLOR-based sampling
Figure 3: Typical multi-slice human brain images acquired with starCEST at 3T. (a) T1 maps by look-locker sequence; (b) B0 maps acquired with dual-echo sequence, The (c) amideCEST maps (ΔZamide) and the corresponding (d) apparent relaxation rate (Ramide) maps extracted with the PLOF method by including the B0 and T1 maps, respectively.
Comparison of the amideCEST maps without and with MLSVD post-processing. (a) The original amide CEST maps extracted using PLOF without MLSVD denoising. (b) MLSVD denoising applied with truncation numbers 48, 48 and 10.
