(A) T₂ weighted image of the mouse hind leg used for anatomical guidance. The extracted maps of (B) $R_{1.95}^{max}$ and (C) $R_{2.5}^{max}$ determined by the PLOF method using the Z-spectrum recorded with a saturation power of 1 μT. (D) The Cr and (E) PCr concentration maps calculated using Eqs. 9 and 10, respectively. (F) The NMSE map calculated using Eq. 11 for evaluating the PLOF fitting.
