In addition, our results showed that there was significant correlation between the Cho/water and Ki-67 SI for EC (r = 0.701, P < 0.001) (Fig. 7A), between Cho/water and tumor size (r = 0.538, P < 0.001) (Fig. 7B), between Cho/water and number of voxel (ρ = 0.500, P < 0.001) (Fig. 7C), and between Ki-67 SI and tumor size (r = 0.609, P < 0.001) (Fig. 7D). Here, MKI67 is linked to neoplasm.
