摘要
目的 应用二次谐波显像技术对临床怀疑为肥厚型心肌病的患者进行检查 ,以提高肥厚型心肌病的诊断能力。方法 临床怀疑为肥厚型心肌病的患者 4 7例。采用美国HPSONOS 5 5 0 0型彩色多普勒超声诊断仪 ,探头频率 2～ 4MHz。该仪器配有二次谐波超声显像功能 ,在标准的左室长轴、二尖瓣水平至心尖部的左室短轴、心尖四腔及二腔切面测量室间隔及左室壁各节段的厚度。结果 二次谐波显像技术能够在 17例 (36 .17% )的常规二维超声图像不佳的患者中获得满意的图像 ,所有患者获得了准确的测量结果并明确了诊断。结论 二次谐波显像技术能够提高肥厚型心肌病的诊断率 。
Objective\ To evaluate the clinical utility of native tissue harmonic imaging in the diagnosis of hypertrophic cardiomyopathy (HCM). Methods\ Forty-seven cases with clinically suspected HCM were studied with HP SONOS 5500 tissue harmonic imaging (THI) system. Results\ Good THI images were obtained in 17 patients whose regular two-dimensional echocardiographic images were not clear enough to detect the endocardium. All the patients had HCM by THI.Conclusions\ THI can increase the detection rate of HCM, and it is very important for detecting the apical hypertrophic cardiomyopathy (AHCM) and the non-obstructive hypertrophic cardiomyopathy (NOHCM).
