In order to evaluate the reproducibility of Diffusional Kurtosis Imaging (DKI) in uterine cervix in vivo, 20 healthy volunteers underwent duplicate MRI and DKI scans with an interval of 24 hours to 14 days. Metric K and D were obtained and measured. ICCs, CVs of both intra- and inter- observer showed the perfect stability of D and K in two scans. Therefore, DKI appears reproducible in providing useful information of non-Gaussian diffusion behavior in uterine cervix. And it is stable in the application in clinical researches.
