ABSTRACT
Objective ToinvestigatethevalueofDCEGMRIimagingindifferentiatingmalignanttransformationinvertedpapilloma (IP)frombenignIP.Methods 24casesofIPconfirmedbyoperationandpathologywerecollectedfromJanuary2012toJanuary 2018,including14caseswithbenignIPand10patientswithIP malignanttransformation.Thedynamicenhancementparametersof thetwogroups,theproductoftransferconstant(Ktrans),therefluxrateconstant(Kep),theextravascularextracellularspacevolume fraction (Ve)andthedifferenceoftheareaundertheinitialcurve(iAUC)wereanalyzed.Thesensitivityandspecificityofdifferent parametersintheidentificationofbenignIPandIP malignancytransformationwereevaluated.Results Thereweredifferencesno significantdifferenceinageandsexbetweenbenignIPgroupandIPmalignanttransformationgroup.Therewasasignificantdifference abouttheconvolutedcerebriformpatternbetweenthetwogroups(P=0.004).Therewasnosignificantdifferenceofstagingbetween thetwogroups(P=0.136).TheKtransvaluesofbenignIPgroupandIPmalignanttransformationgroupwere0.21±0.53 (min-1), 0.36±0.93 (min-1),andtherewasasignificantdifferencebetweenthetwogroups(P=0.000).TheiAUCvaluesofbenignIPgroupand IP malignanttransformationgroupwere29.05±5.45,41.14±9.47,respectively,andthedifferenceofiAUCbetweentwogroupswas statisticallysignificant(P=0.001).TherewasnosignificantdifferenceinKepandVebetweenbenignIPfromIPmalignanttransformation (P>0.05).Conclusion BenignIPhasatypicalconvolutedcerebriG formpatternandtheabsenceofitindicatesmalignanttransformation. Thestagingoflesioncan’tdifferentiatethebenignIPfromIP malignanttransformation.DCEGMRIexaminationisworthyinthe evaluationbenignIPandIP malignanttransformation,especiallyKtransandiAUCvalues.
