ABSTRACT
Objective Toinvestigatetheclinicalvalueofreadoutsegmentationoflongvariableecho-trainsdiffusion-weightedimaging (RESOLVE-DWI)inthediagnosisandstagingofthyroid-associatedophthalmopathy(TAO).Methods Atotalof30consecutivepatientswith TAOand30healthycontrols(HCs)whounderwentRESOLVE-DWIwereenrolledinourstudy.ADCvaluesofextraocularmuscles (superiorrectus,inferiorrectus,medialrectusandlateralrectus)were measuredandcomparedbetween TAOsand HCs,active TAOsandinactiveTAOs,orinactiveTAOsandHCs.ROCanalysiswasperformedtoevaluatethediagnosticvalueofsignificantparametersfor discriminatingactivefrominactiveTAOs.Results TheADCvaluesofallextraocularmusclesinTAOsweresignificantlyhigherthan thoseinHCs(P<0.05).Meanwhile,alltheextraocularmusclesinactiveTAOsshowedsignificantlyhigherADCvaluesthanthose ininactiveTAOs(P<0.05),exceptlateralrectus(P=0.267).WhilstnosignificantdifferenceswerefoundontheADCvaluesofall extraocularmusclesbetweeninactiveTAOsandHCs(P>0.05).ROCanalysisresultsindicatedthattheADCvalueofmedialrectus showedtheoptimalstagingefficacy(cutoffvalue,1.40×10-3 mm2/s;AUC,0.766;sensitivity,92.1%;specificity,59.1%).Conclusion RESOLVE-DWIanditsderivedADCvaluesofextraocularmusclescanassistinthediagnosisofTAO.TheADCvalueofmedial rectushastheoptimalefficacyontheevaluationofitsclinicalactivity.
