TR repetition time; TE echo time; ST slice thickness; AM acquisition matrix; G.0 represents the three kiwis, while G.1–G.3 represent the three group volunteers in 6th–10th, 11th–15th, and16th–20th day of physiological cycle respectively; The values displayed on the table were means within each group. “Mean ± Standard Deviation” was calculated from mean CV values within each group.
