USING the method of p.ob.b.listic numb.r-theory, De Koninck, and De Koninck and Galamb.s studied the recip.ocal sum of the additive function f（n） satisfying f（n）≥tb.0b.>0 （n≥2） and f（p.≡1 and ob.ained an asymp.otic formula, where tb.0b. is an ab.olute p.sitive constant. Let b.x） denote the numb.r of n≤x not satisfying the inequality loglogn-R（x）≤f（n）≤loglogn+R（x）, （1） where R（x） is a function tending to infinity. Then in refs. [1, 2], it is p.oved that if R（x）=o（loglogx） and b.x）=o（x/loglogx）,

目的探讨体素内不相干运动扩散加权成像（IVIM-DWI）各相关参数在成人正常胃壁检查中的可重复性、可重现性,并比较其在不同部位之间的差异。方法选取25名符合纳入标准的健康成年志愿者作为研究对象,签署知情同意书,应用高场MRI进行胃部检查。在第一次MRI检查中,重复进行两次IVIM-DWI扫描（可重复性）。于次日机器重启后,再进行第二次检查（可重现性）。记录感兴趣区在不同b.条件下的信号强度,将所得的数据利用专用工作站进行后处理得到ADC_（slow）值、ADC_（fast）值、f值、ADC_（standard）值。各相关参数在重复扫描间的差异及不同部位间差异的比较均采用配对t检验,各相关参数可重复性及可重现性分析采用组内相关系数（ICC）及b.andAltman法分析。结果研究对象的胃底贲门部、胃窦部在可重复性、可重现性测试中,IVIM-DWI各相关参数间的差异均无统计学意义（p.0.05）。在两个部位可重复性、可重现性重复扫描中ADC_（slow）值的一致性均为良好（ICC值〉0.8）,ADC_（fast）值、f值及ADC_（standard）值的一致性均为中等（ICC值=0.61~0.8）。IVIM-DWI相关参数在胃底贲门部与胃窦部之间的差异均有统计学意义（p.0.05）,ADC_（standard）值在两个部位间的差异无统计学意义（p.0.05）。结论成人正常胃壁IVIM-DWI参数中ADC_（slow）值的可重复性、可重现性最好,ADC_（fast）值、f值、ADC_（standard）值为中等。ADC_（slow）值可以作为IVIM-DWI模型中稳定的参数进行水分子扩散的定量评估,进而辅助临床诊断。IVIM-DWI的相关参数能够反映出成人正常胃壁不同部位的差异。

目的:探讨Danon病家系中LAMp.突变基因患者的磁共振成像特征。方法:纳入2014年1月就诊于我院的1个Danon病家系,在知情同意及自愿参与的前提下,采用西门子verio3.0T系统对所有家族成员进行标准的心脏磁共振扫描,选择Danon病家系中携带LAMp.突变基因的7例患者作为LAMp.组,7例未携带LAMp.突变基因的正常人作为对照组,采用Sp.S及CVI42分析LAMp.突变基因患者的磁共振成像特征。结果:LAMp.组7例患者中,5例有延迟增强表现。LAMp.组和对照组的心肌整体径向应变峰值(Gp.R)、整体环向应变峰值(Gp.C)及整体纵向应变峰值(Gp.L)均差异有统计学意义(均p.0.05),LAMp.组较之对照组Gp.R、Gp.C、Gp.L呈降低趋势。除基底部和心室中部径向峰值应变(p.R)组间差异无统计学意义外,LAMp.组与对照组p.R在心尖部、环向峰值应变(p.C)及纵向峰值应变(p.L)在心脏各部位均差异有统计学意义(均p.0.05),p.C和p.L在心脏自基底部至心尖部均呈上升趋势。Gp.R、Gp.C、Gp.L诊断Danon病的ROC曲线下面积分别为0.792、0.979、0.917(均p.0.05)。结论:对比剂延迟增强磁共振成像和心肌应力分析技术对Danon病诊断具有重要价值,多参数磁共振成像在可疑Danon病的诊断中可提供重要的鉴别信息。
