Abstract: Objective ToassessthediagnosticvalueoftextureanalysisofDCEGMRIindifferentialofbreastfibroadenoma(FA) andinvasiveductalcarcinoma(IDC).Methods TheMRIdataof51patients(21breastFA,30IDC)confirmedbysurgicalpathology wereretrospectivelystudied.6texturefeaturesoftheDCE metricparameters,includingforwardGvolumetransfercontrant(Ktrans)、reverse volumetransferconstant(Kep)andextravascularextracellularspacevolumefraction(Ve),weregeneratedfrom manuallyselected ROIofthelesions.ROCcurveoftextureparameterswereusedindifferentialdiagnosisofFAandIDC.Results Significantdifferences werefoundbetweenFAandIDCforallDCEGMRImetricsexceptforKepkurtosis,Veenergy,entropy,andkurtosis.Themeanvalueof Ktrans、KepandVe were0.79、0.92、0.73,respectively.Conclusion ThehistogramtexturecharacteristicsontheDCEquantitativeparameterof FAandIDChavesignificantlydifferences.HistogramtextureanalysisofDCEGMRIdemonstratestheabilityofdifferentiatingFA fromIDC,andprovidesreliableresultsforclinicaldiagnosis,whichishelpfulforthechoiceofclinicaltreatment.
