1、超声心动图和核素心10I池显像评价心功能的对比研究超声心动图和核素心血池显像评价心功能的对比研究中文摘要目的:超声心动图和放射性核素现在已经广泛应用于对心脏疾病的诊断。心脏功能评估对临床诊断和治疗都具有十分重要的意义。我们通过超声心动图、平衡法核素心血池显像对研究对象进行心功能的检测,对这两种方法进行对比研究,了解两种方法在测定心功能上的相关程度,为临床提示在不同情况下评价心功能较为理想的检查方法。方法:入选患者共20例,采集相关病史和临床资料,在48—72小时内行超声心动图和放射性核素检查。应用M型超声在患者胸

3、冠心病差(r=0.63,p>0.05vsr=0.72,p=50mm组的相关性也较LVIDd<50mm组差(r=O.59,p>0.05vsr=O.70,p=0.05)。平衡法测定左室舒张功能,冠心病组的PFR,1/3FF,1/3FR均比非冠心痛组降低(P4、室几何形状和室壁节段运动的影响,故在心室结构有明显改变、室壁活动异常的情况下,建议临床医生首先考虑平衡法心血池显像。平衡法核素心血池显像在舒张功能减退的诊断上较多普勒超声敏感。在患者心室率较快影响多普勒超声测量时,建议选用核素心血池显像。关键词:平衡法核素心皿池显像;超声心动图;左室功能超声心动图和核素心血池显像评价心功能的对比研究Comparisionofgatedblood-poolSPECTwithechocardiographyintheevaluationofleftventricularfunctio5、nAbstractobjectives:EchocardiographyandNuclearimagingmethodhavebeenwidelyusedindiagnosisofheartdiseases.Assessmentofventricularfunctionisveryimportantwhilediagnosingaswellastreatingdisease.Inthisstudy,weusedUCGandSPECTtoassessventricularfunction.Theresultswer6、ecomparedtofindouttheidealoneindi疵rentconditons.Methods:10patientswithconoraryheartdisease(CAD)and10patientswithoutconoraryheartdisease(non—CAD)wereenrolledinthissmdgHistoryandmedicaldatawerecollected.Gatedblood-poolsinglephotonemissioncomputedtomography(SPEC7、T)andechoeardiographywereperformedinconsecutivepatientswithin48—72hoursofeachothellSPECTdata,includingLVejectionfractionandPFR,TPF,1/3FF,1/3FRwereprocessedusinganautomaticalgorithmwhereasechocardiographyusedstandardtechniques.ThecorrelationbetweenSPECTandecho8、cardiographyinLVEFwerestudied.Inthemeanwhile,diastolicdataalsowereevaluatedbetweenCADandnon—CAD.Results:Thecorrelationsbetweengatedtomographyandechocardio目aphywithrespecttoleftventricular
