2、巴瘤4例、转移性肿瘤7例)分别进行CEUS~WCECT检查,比较两种影像学检查技术的增强表现。结果:CEUS和CECT对脾病灶内部的血流显示率均为100%,对病灶内部血流灌注的敏感程度均优于彩色多普勒(71.4%)(P<0.05)。CEUS和CECT反映的脾脏病变增强方式完全一致。CEUS对增强过程中特殊表现(树枝状、结节状和筛孔状增强)的检出率为57.1%(12/21),与CECT相比,病灶血流灌注的增强表现更多样化,两者比较差异有统计学意义(P3、实质性病变的血流动力学特点,有助于脾肿瘤的鉴别。【关键词】超声造影;计算机断层扫描:造影剂;脾肿瘤中图分类号:R445.1;R445_3文献标志码:A文章编号:1008.617X(2015)01.0030.05Comparisonofenhancementfeaturesofsplenicsolidtumorsoncontrast-enhanceduItrasOnOgraphyandcontrast-enhancedCTCAOJiaying,zHANGHui,WANGWenping,DINGHong4、,HUANGBeUian,DINGYing,YANGShan(1.Depa~mentofDiagnosticUltrasound,ZhongshanHospital,FudanUniversity;ShanghaiInstituteofMedicalImaging,Shanghai200032,China;2.DepartmentofDiagnosticRadiology,ZhongshanHospital,FudanUniversity;ShanghaiInstituteofMedicalImag5、ing,Shanghai200032,China)Correspondenceto:WANGwen—pingE·mail:puguang61@126.com【Abstract】Objective:Tocomparetheenhancementfeaturesofsplenicsolidtumorsoncontrast-enhancedultrasonography(CEUS)andcontrast—enhancedCT(CECT).Methods:Twenty-onepatientswithfoca6、lspleniclesionswereenrolled,including5casesofhemangioma,5casesoflympho—hemangioma,4casesoflymphomaand7casesofmetastases.Theirenhancementappearanceswerecompared.Results:ThevasculardisplayingratesofCEUSandCECTwereboth100%.Thetwocontrastmethodsweremoresen7、sitivethancolorDopplerultrasoundindisplayingtheperfusionofthespleniclesions(71.4%)(尸<0.05).Hemodynamiccharacteristicsofthespleniclesionswereaccordant.ThedetectionrateofspecialperformanceofCEUSwas57.1%(12/21)intheenhancementprocess.ComparedtothatofCECLt8、heenhancementonCEUSwasmorediversified.ThediferencewasstatisticallysignificantbetweenCEUSandCECTimagesfP<0.05).Conclusion:BothCEUSandCECTcandemonstratehemodynamicfeaturesofsplenictumorssensitively,whichishelpfulindiferentialdiagnosisofsp
