2、、数目、分布。分析CMBs与其它,临床表现和影像学表现的相关性。结果:61例中有15例检出CMBs(发生率24.6),均发生在糖尿病合并高血压组,单纯糖尿病组未发现CMBs。糖尿病伴有急性脑卒中患者33例,其中13例发生CMBs(发生率为39.4)。15例脑内有CMBs组与46例脑内无CMBs组的血糖水平(最高值、最低值、控制值)、年龄和病程采用t检验进行比较,发现有CMBs组平均空腹血糖最低值低于无CMBs组,且差异有统计学意义(f一0.046,P3、组,采用Fishers精确概率法检验,发现各组的CMBs发生率不同,且差异有高度统计学意义(P<0.01)。结论:SWI能清晰显示糖尿病患者CMBs;单纯糖尿病患者不易发生CMBs,糖尿病合并高血压CMBs发生率明显增加;糖尿病患者伴有急性脑卒中和脑白质疏松时易发生CMBs。【关键词】磁共振成像;磁敏感加权成像;脑内微出血;糖尿病【中图分类号】R445.2;R743.34;R587.1;R587.2【文献标识码】A【文章编号】1000~0313(2013)1212540dApplicationof4、SWIindiagnosingcerebralmicrobleedsassociatedwithdiabetesHEJin—long,NIUGuang—ruing,HANXiaodong,eta1.DepartmentofMR,theAffiliatedHospitalofInnerMongoliaMedicalUniversity,Hohhot010050,P.R.China[Abstract]Objective:Patientswithdiabeteswereexaminedwithsusce5、ptibilityweightedimaging(SWI)ofthebraintofindwhethercerebralmicrobleeds(CMBs)occurfrequentlyandtoexplorethecorrelationofthecerebralmicrobleedswithbloodglucoselevel,acutestrokeandleukoaraiosisdegree.Methods:61casesofdiabeteswereexaminedbySWI.21caseshad6、onlydiabetes,and40caseshaddiabeteswithhypertension.AIlpatientsunderwentMRscanincludingconventional})rainMRsequences(TWI,T1WI,DWI)andESWANsequences.TheCMBsoccurrencerate,thenumberanddistributionwererecorded,andthecorrelationofCMBswithotherclinicalmater7、ialsandimagingfindingswasanalyzed.Results:CMBsweredetectedin15cases(24.6),alloccurringinthegroupofdiabeticpatientswithhypertension,itwasnotfoundinthesimplydiabeticgroup.Diabeteswithacutestrokewere33cases,amongwhich13caseshadCMBs(39.4).15casesofCMBsgro8、upand46casesofnon—CMBsgroupwerecomparedwitht-testincludingglucoselevels(maximumvalue,mininlulqnvalue,thecontrolvalue),ageandcourseofthedisease.ItwasfoundthatthelowestfastingbloodglucosevalueintheCMBsgroupwaslowerthanthatinthegroupwithoutCMBs。a
