Abstract: Objective TostudythevalueofDCE-MRItechniqueindifferentialdiagnosisofthyroidadenoma(TA)andpapillary thyroidcarcinoma(PTC).Methods 71thyroidnoduleswereanalyzedretrospectively,includingTA (28cases)andPTC (43cases), whichwereconfirmedbyhistologyafterMRIscanning.AfterconventionalMRIandDCE-MRIwereperformed,TICswereobtained. ThediagnosticindicatorsofPTCwithDCE-MRItechniquewereanalyzed,includingthesensitivity,specificity,accuracy,positivepredictive valueandnegativepredictivevalue.Results 23TAshowedⅠcurve,41PTCshowedⅢcurve,5TAand2PTCshowedⅡcurve, withstatisticallysignificantdifference(P＝0.000).Thesensitivity,specificity,accuracy,positivepredictivevalueandnegativepredictive valuewere95.3%,82.1%,90.1%,89.1%and92.0%,respectively.Conclusion DCE-MRItechniquehelpstoidentifyTAandPTC, andTICcanbeamorecomprehensivemethodtoanalyzemicrovascularhemodynamicprocessesofTAandPTC.
