Abstract：ObjectiveTo evaluate the reproducibility of magnetic resonance imaging (MRI)diffusional kurtosis imaging(DKI)in detecting of cervical carcinoma.Methods10 patients and 10 healthy volunteers in our hospital from June to December in 2016 were selected and underwent duplicate MRI scans by using DKI with an interval of 24 hours to 14 days.The metric K and D were obtained from parametric maps and evaluated by statistical software SPSS 19.0.ResultsThe D value of intra group variation coefficient(ICC)of the total subjects,volunteers,and cervical cancer patients were 0.899,0.935 and 0.828,respectively.The ICC of parameter K was 0.870,0.871 and 0.877,respectively.The coefficients of variation of the D in the total subjects,the volunteers and the patients with cervical cancer were 17.23%,16.43%and 16.51%,respectively.The coefficients of variation of parameter K were 17.85%,20.16%and 12.28%,respectively.ConclusionDK imaging sequence appears reproducible in detecting the non Gauss diffusion of water molecules in cervical carcinoma.
