简介：摘要目的分析MRI不同序列组合在判断Ⅰ期子宫内膜癌肌层浸润深度中的应用价值.方法收集有完整临床及MRI资料的经病理证实的子宫内膜癌病例５２例,分析子宫内膜癌的MRI信号特征,按T２WI结合T１WI、T２WI结合扩散加权成像(DWI)、T２WI结合增强扫描不同的序列组合分别观察肿瘤浸润肌层的深度,根据２００９年FIGO分期原则进行分期,并与病理分期结果对比.结果子宫内膜癌的MRI表现为子宫内膜不规则增厚,T２WI呈略高信号,结合带信号中断,DWI呈高信号,增强呈轻度渐进性强化;MRI不同序列组合对Ⅰ期子宫内膜癌肌层浸润深度的判断结果与病理结果对比T２WI结合T１WI正确判断３９例;T２WI结合DWI正确判断４６例;T２WI结合增强扫描正确判断４８例.结论T２WI结合DWI与T２WI结合增强扫描对判断Ⅰ期子宫内膜癌肌层浸润深度的准确率明显高于T２WI结合T１WI组合,T２WI结合DWI与T２WI结合增强扫描对判断Ⅰ期子宫内膜癌肌层浸润深度的准确率无明显差异.关键词子宫内膜癌;MRI;扩散加权成像;增强扫描ThevalueofMRIsequencesofdifferentcombinationsinjudgingⅠperiodendometrialcarcinomainfiltrationdepthofmuscularlayerBaoya－hongChenggang(Deparmentofmedicalimage,people＇shospitalofHaimen,Jiangsu２２６１００China)AbstractObjectivetoanalyseThevalueofMRIsequencesofdifferentcombinationsinjudgingⅠperiodendometrialcarcinomainfiltrationdepthofmusＧcularlayer．MethodstocollectacompleteclinicalandMRIdataof５２casesofendometrialcarcinomacases,whichwasconfirmedbypathology,analyzingMRIsignalfeaturesofendometrialcarcinoma,RespectivelytoobservethetumorinfiltrationdepthofmuscularlayeronT２WIwithT１WI,T２WIwithdiffusionweighＧtedimaging(DWI),T２WIwithcontrast－enhanced．AccordingtotheprincipleofFIGOstagingstagingin２００９,andcomparedwithpathologicalstagingresult．ResultsTheMRIfeaturesofendometrialcarcinomaisendometriumirregularthickening,slightlyhighsignalonT２WI,interruptjunctionzone,highsignalonDWI(diffusionweightedimaging)andamildprogressivereinforcementoncontrast－enhanced．CombinationofdifferentMRIsequencesonthedepthofmuscularⅠperiodendometrialcarcinomainfiltratingjudgmentresultcomparedwiththepathologicalresultsT２WIwithT１WIcorrectjudgment３９cases;T２WIwithDWIcorrectjudgment４６cases;T２WIwithcontrast－enhancedCorrectjudgment４８cases．ConclusionTheaccuracyinjudgingⅠperiodendometrialcarcinomainfiltrationdepthofmuscularlayerofT２WIwithDWIandT２WIwithcontrast－enhancedwasobviouslyhigherthanthatofT２WIwithT１WI,noobviousdifferＧencewKaesyfowuonrddsinjudgingⅠperiodendometrialcarcinomainfiltrationdepthofmuscularlayerbetweenT２WIwithDWIandT２WIwithcontrast－enhanced．Endometrialcarcinoma;Magneticresonanceimaging(MRI);Diffusionweightedimaging(DWI);Contrast－enhanced中图分类号R４４５．１文献标识码B文章编号１００８－６３１５(２０１５)１０－０３６０－０２

简介：摘要目的探讨分析在脑导水管梗阻临床诊断中磁共振3D-CISS序列应用价值。方法选取2011年7月-2014年4月我院所收治的55例脑导水管梗阻患者，借助于3.0T超导MR扫描仪实施3D-CISS、FLASHT1WI以及TSET2WI序列扫描，同时对磁共振3D-CISS序列原始图像实施重建，就三种序列脑导水管病变显示情况进行观察比较。结果3D-CISS、FLASHT1WI以及TSET2WI三种序列在脑导水管梗阻病变显示率上各为100%、72.7%、16.4%，经统计学处理分析，差异明显有统计学意义（P＜0.05）。结论从本次研究结果来看，相对于常规序列而言，在脑导水管梗阻病变的显示上，磁共振3D-CISS所存优势明显，若条件允许可优先选用这种序列进行检查诊断。
