ABSTRACTObjectiveTo investigate the clinical value of contrast-enhanced ultrasound（CEUS）combined with micrflowimaging（MFI）inthediagnosis of protruding galbladderlesions.MethodsOnehundredpatients with pathologically confirmed protruding galbladderlesions（10O intotal）were selected.Among them，therewere 59 non-tumorlesions（non-tumor group）and 41 tumorlesions（tumor group）.The differences in CEUSand MFIexaminationresults betwen thetwo groups were compared.TheconsistencyofCEUS，MFI，andtheircombinationindiagnosing protrudinggalbladderlesions wasanalyzed，the diagnosticsensitivity，specificity，andaccuracywerecompared.ResultsCEUSshowedthatthere were statisticallsignificant diferencesigreiooectel，loooigalitgityofallntetall （204號 P <0.001）.MFIshowedthattherewerestatisticallysignificant diferenesinblodflowgradingandvascularclasification between the two groups（both P<0.001 ）.CEUS accurately diagnosed 51 non-tumor lesions and 36 tumor-lesions，showed good consistency with pathological results（Kappa=0.734， P <0.05），the sensitivity，specificity，and accuracy were 86.44% ！ 87.80% ， and 87.00% ，respectively.MFI accurately diagnosed 48 non-tumor lesions and 36 tumor lesions，showed moderate consistency with pathological results（Kappa=0.673， P<0.05 ），thesensitivity，specificity，and accuracywere81.36 % ，87.80 % ，and 84.00% ， respectively.Thecombinationof thetwomethodsaccuratelydiagnosed56non-tumorlesionsand39tumor lesions，showed excellent consistency with puthological results（Kappa=0.897， P<0.05 ），the sensitivity，specificity，and accuracy were 94.92% ，

膽囊隆起性病變是指起源于膽囊壁并向膽囊腔內(nèi)突出的所有非結(jié)石性病變，病理學上分為非腫瘤性病變（膽固醇性息肉、炎性息肉等）和腫瘤性病變（腺瘤、膽囊癌等）兩大類。（剩余6702字）
