肝转移癌超声多普勒肝血流灌注指数的测定        摘要目的:评价肝血流灌注指数诊断肝转移癌的临床价值。方法:利用脉冲多普勒超声测定了4组110例肝动脉、门静脉血流量,并计算出相应的肝静脉血流与门静脉血流的比值DFR和多普勒肝血流灌注指数DPI。结果:4个组之间的肝脏总血灌注量相差不明显,P>。肝转移癌组、±、±±、±,明显高于对照组、肝内无转移癌组,±、±±、±,P均<。DPI、%、%、%。结论:本组资料表明,DPI或DFR不能区别肝转移癌和肝原发癌,但在已知患者有恶性肿瘤的情况下,DPI、DFR可成为临床早期检出肝转移瘤的十分有价值的指标。关键词肝转移瘤超声多普勒血流灌注指数MeasurementofUltrasoundDopplerPerfusionIndexinDetectionofHepaticMetastasesHeSheng,etalGeneralNavyHospital(Beijing100037) Abstract Parpose::Hepaticarterialandportalvenousbloodflowweremeasuredin110cases,onwhichcalculationsoftheratioofhepaticarterialtototelliverbloodflow(DPI)andtheratioofhepaticarterialtoportalvenousbloodflow(Dopplerflowratio,DFR):Whiletherewerenotdifferenceamongthetotalhepaticalperfusionsofthefourgroups,P<,thereweresignificantseparationsbetweenhepaticthegroupofoverthepaticmetastases、,±、±±,±,andthegroupofcontral,groupoffreehepaticmetastases,±,±±,±,P<:ThedatasuggestedthatDPIorDFRcouldn?,butDPI、eaclinicallyusefulindicatorforearlierdetectinganddiagnosinghepaticmetastasesifotherkindsofmalignanttumorswhichthepatientsaresufferinghavebeenknown.
