Tab. 5:

Comparison of Cr recovery constants measured on volunteers 1 and 2, utilizing 2D-CrCEST and 3D-CrCEST in the same session. A minimum of 20 minutes separation was maintained between successive PFEs to ensure full creatine recovery.

Volunteer	Creatine rate constant (in seconds) measured using 2D CrCEST	Creatine rate constant (in seconds) measured using 3D CrCEST	Coefficient of variance (in %)
# 1	LG: 74.56 Per: 55.30	LG: 71.60 Per: 61.50	LG: 2.86 Per: 7.51
# 2	LG: 71.17	LG: 58.74	LG: 13.53
