2023年2月第30卷第2期MSCT平扫联合三期动态增强扫描诊断肝细胞癌的价值分析郭勇，王富林，武卫杰，王峰，温平贵（周口市中心医院CT室，河南周口466000）【摘要】目的分析多层螺旋CT（MSCT）平扫联合三期动态增强扫描诊断肝细胞癌（HCC）的价值。方法回顾性分析85例HCC患者的临床资料，所有患者均接受MSCT平扫和三期动态增强扫描，比较MSCT平扫与三期动态增强扫描的病灶检出率，分析HCC病灶的密度分布情况。结果动脉期、延迟期的病灶检出率高于平扫和门静脉期（P＜0.05）；联合诊断的病灶检出率为100.00％，高于平扫的65.26％（P＜0.05）。HCC病灶在动脉期主要表现为高密度影，在门静脉期和延迟期主要表现为低密度影。结论MSCT平扫联合三期动态增强扫描可显著提升HCC患者的病灶检出率，尤其是对微小病灶的检出。【关键词】肝细胞癌；多层螺旋CT；动脉期；门静脉期；延迟期；平扫中图分类号：R445.3文献标识码：Adoi:10.3969/j.issn.1674-4659.2023.02.0155AnalysisontheValueofMSCTPlainScanCombinedwithThree-PhaseDynamicEnhancedScanintheDiagnosisofHepa-tocellularCarcinoma//GUOYong,WANGFulin,WUWeijie,WANGFeng,WENPinggui(CTRoom,ZhoukouCentralHospital,Zhoukou466000,China)[Abstract]ObjectiveToanalyzethevalueofmulti-slicespiralCT(MSCT)plainscancombinedwiththree-phasedynamicenhancedscaninthediagnosisofhepatocellularcarcinoma(HCC).MethodsTheclinicaldataof85patientswithHCCwereretrospectivelyanalyzed.AllpatientsunderwentMSCTplainscanandthree-phasedynamicenhancedscan.ThelesiondetectionratesofMSCTplainscanandthree-phasedynamicenhancedscanwerecompared,andthedensitydistributionofHCClesionswasanalyzed.ResultsThelesiondetectionratesinarterialphaseanddelayedphasewerehigherthanthoseinplainscanandportalveinphase(P<0.05);Thelesiondetectionrateofcombineddiagnosiswas100.00%,higherthan65.26%ofplainscan(P<0.05).HCClesionsmainlyshowedhighdensityinarterialphaseandlowdensityinportalvenousphaseanddelayedphase.ConclusionsMSCTplainscancombinedwiththree-phasedynamicenhancedscancansignificantlyimprovethedetectionrateofHCC,especiallyforsmalllesions.[Keywords]Hepatocellularcarcinoma;Multi-slicespiralCT;Arterialphase;Portalveinphase;Delayedphase;Plainscan肝细胞癌（HCC）具...
