ABSTRACT
Objective ToexploretheMRIperformanceofpapillarythyroidcarcinomawithhobnailfeatures(HPTC)andthedifferential diagnosisfromclassicpapillarythyroidcarcinoma(CPTC).Methods Dataof93patientswithconfirmedPTCandMRIexamination oneweekbeforesurgerywereretrospectivelycollected.Thedifferencesoftheage,sex,tumorsize,ADCvaluesand MRIfeaturesof HPTCandCPTCweredetermined.Results 10HPTCand78CPTCwereincludedinthisstudy.ThefrequencyofT2WIsignificantly highsignal,segmentationlinearlowsignal,lacesignandgyrus-likestructureofHPTCwassignificantlyhigherthanthatofCPTC (P=0.000).ComparedtoCPTC,HPTCshowedmoreirregularshape(P=0.005),largervolume(P=0.025),moremixedT2WI andDWIsignals(P=0.002,0.028,respectively),higherADCvalues(P=0.019),anddelayedmass-likeenhancement(P=0.041). Conclusion HPTClesionshavelargervolume,irregularshape,mixedT2WIsignals,mixedDWIsignalsandhigherADCvalues. Significantlyhighsignal,segmentationlinearlowsignal,lacesignandgyrus-likestructurearecommonlyobservedonT2WI.Delayed mass-likeenhancementpatternismorecommon.ThesecharacteristicscouldcontributetothediagnosisofHPTC.
