ABSTRACT
Objective ToinvestigatetheeffectofhighGintensityfocusedultrasound (HIFU)ablationonuterinefibroidswithdifferent withdifferentT2Gweightedimage(T2WI)signalintensity.Methods 357patientswithsymptomaticuterinefibroidstreatedwith HIFU wereretrospectivelyanalyzed.AccordingtoT2WIsignalcharacteristics,fibroidsweredividedinto4groupshypointensity,isointensity, hyperintensityand mixedintensity.The HIFUtreatmentparametersandablationeffectsofeachgroup werecomparedby O n eG W a y analysisofvariance.Results Theaverageageofthepatientswas(38.5±6.2)y,andtherewerenosignificantdifferencesinbaseline data(P>0.05).AllpatientssuccessfullycompletedHIFUtreatment,withtheaveragetreatmenttimeof(128.3±60.9)min,theaverage nonGperfusionvolumerate(NPVR)of(74.4±14.7)%,andtheaverageenergyefficiencyfactor(EEF)of(7.1±4.8)j/mm3.Theresults of O n eG W a y analysisofvarianceshowedthattheT2WIhypointensitygrouphadshortersonicationtime,treatmenttimeand1cm3 sonicationtime,smallertreatmentpowerandEEF,largerNPVR,comparingwiththehyperintensitygroup withstatisticallysignificant differences(P<0.05).Conclusion UterinefibroidswithT2WIhypointensityhavelowwatercontentandhighenergydepositionefficiency, whicharemoresuitableforHIFUablation.
