No differences in the diffusion properties of the ovaries were observed throughout the menstrual cycle using a biexponential model.
Figure 1. Representative ADC1 map of the ovaries overlaid on T2 FSE images in a single participant through each week (A-D) of the menstrual cycle. Asterisks in C and D indicate locations where distortion artifacts were severe due to the proximity of the ovary to the colon resulting in incomplete distortion correction of the ovary.
Figure 2. The diffusion properties of ovaries were described using a bi-exponential model Si(b) = S0[(1-β)e-bADC1+βe-bADC2]. Estimated A) ADC1, B) ADC2, and C) β throughout the menstrual cycle for six participants (colors) are shown.
