[摘要]目的：分析不同病理分型急性阑尾炎的高频声像图和彩色多普勒血流特征并评价其诊断价值。方法：回顾性分析141例经手术病理或临床证实的急性阑尾炎患者应用高频彩色多普勒超声诊断。结果：各型阑尾炎诊断符合率90％左右。结论：高频彩色多普勒超声诊断不同分型急性阑尾炎有较高实用价值，诊断应以高频声像图为基础，结合彩色多普勒血流丰富程度分析。　　[关键词]急性阑尾炎；高频声像图；彩色多普勒血流显像　　applicationofhighfrequencycolordopplerultrasonographyindiagnosisandclassificationofacuteappendicitis　　yangjian-an　　（ultrasounddepartment,thepeople’shospitalofshaxiinthecountyoftaicang，taicang215421,china）　　[abstract]objective：toexplorethecharacteristicsofacuteappendicitiswithdifferentpathologicalclassificationonhighfrequencyultrasonographyandcolordopplerflowimaging（cdfi）andtoevaluatetheirdiagnosticvalue.methods：atotalof141casesprovedtobewithacuteappendicitisbyoperationandpathologywereanalyzedrespectivelyanddiagnosedwithhighfrequencycolordopplerultrasonography.results：thediagnosticaccuracyrateofultrasonographywas90％andtherewasdeepsignificance.conclusion：high-frequencycolordopplerultrasounddiagnosisofdifferenttypesofacuteappendicitishavehighpracticalvalue.diagnosisshouldbeanalysisbasedonhigh-frequencyaudio-visualmap-basedandcombinedwithcolordopplerflowanalysisoftheextentoftherich.　　[keywords]acuteappendicitis;highfrequencyultrasonography;colordopplerflowimaging　　急性阑尾炎是临床最常见的急腹症之一，要求尽快明确诊断以采取相应的治疗措施。
