Abstract:
Objective ToevaluatethevalueofMRDKIandDWIindiagnosingendometrialcarcinomaandevaluatingitspathologicalgrade. Methods TheDKIandDWIdataof48patientswithendometrialcarcinomaand27patientswithnormalendometrium wereanalyzed retrospectively.Thevaluesofmeankurtosis (MK),meandiffusion (MD)andADCinendometrialcarcinomaandnormalendometrium were measuredrespectively.Thesimilaritiesanddifferencesoftheparametersbetweentheendometrialnormalgroup(G0)andtheendometrialcarcinoma group (G1,G2,G3)werecomparedandanalyzed.TheROCcurvewasemployedtoevaluatethediagnosticefficacyandthresholdof eachparameter.P earson correlation wasappliedtoanalyzethecorrelationbetweeneachparametervalueandpathologicalgrade.Results The MK valuesincreasedgradually,meanwhiletheMDandADCvaluesdecreasedgraduallyinG0,G1,G2andG3groups.ExceptforMDand ADCvaluesbetweenG0andG1groups,othervalueswerestatisticallysignificantdifferent(P<0.05)betweendifferentgroups.In differentiatingoftheG0/(G1+G2+G3),G0/G1,G1/G2,G2/G3,theMKvalueshadthehighestdiagnosticefficacy(AUC=09.2,07.6,09.0,0.96, P<0 .05 ).M oreover ,in the correlation of pathological grading ,M K>M D>A D C (r=0 .850 ,0 .781 ,0 .709 ,P<0 .05 ).Conclusion Both DKIandDWIcandiagnoseandevaluatepathologicalgradeofendometrialcarcinoma.ComparedwithDWI,DKIembracesmoreperfectmathematical modelandmoresensitiveparameters,andcanbeusedasaneffectivemethodtoevaluatethepathophysiologicalfeaturesofendometrialcarcinoma.
