摘 要:旨在评价多平面经 食管体元模型动态三维超声显像在心血管病定量诊断中的价值。作者对89颗猪心、8条离体血管、16个血管支架、12个人离体二尖瓣膜、17条犬、15例正常人和164例心脏病患者进行研究。图像采集采用美国Hewlett Packard Sonos 2500多功能超声诊断仪和5MHz多平面经食管超声探头。三维重建采用德国TomTec ECHOSCAN计算机工作站。结果显示,与金标准对照,多平面经食管体元模型动态三维超声显像能够准确定量左室容积(r=0.986实验,r=0.94-0.96临床)、左室游离壁心肌重量(r=0.97实验)、右室容积(r=0.95实验)、右室游离壁心肌重量(r=0.97离体;r=0.96在体)、梗死心肌的心肌重量(r=0.95)、房间隔缺损的大小(r=0.95-0.97实验;r=0.94-0.98临床)、室间隔缺损的大小(r=0.95-0.96实验;r=0.96-0.99临床)、心脏肿瘤的大小、二尖瓣脱垂所累及的部位,瓣叶节段和范围、二尖瓣膜的体积(r=0.98)、二尖瓣返流往容积(r=0.85、主动脉瓣返流柱容积(r=0.91)、血管直径(r=0.99、血管支架直径(r=0.96)和支架与管壁的间隙。结论:多平面经食管体元模型动态三维超声显像在心血管病定量诊断中具有重要价值。To evaluate the multi-plane transesophageal three-dimensional ul-trasonic imaging (3-D) in quantitative mea- surement of cardiovascular diseases, 89 pig heart specimens, 8 arteries, 16 vascular stents, 12 human mitrai valvular specimens, 17 dogs, 15 normai subjects and 164 patients with heart diseases were studied. Tomtec E-choscan system and HP Sonos 2500 with 5 MHz multiplane transesophageal transducer were used for data acquisition and analysis re-spectively. Results: good correlation was ob-tained between 3-D and gold Standard: left ventricular volume(r=0. 986 in experimental; r=0. 94 -0. 96 in patients); left vetricular my-ocardial mass(r=0.97 in experimental); right ventricular volume(r=0. 95 in experimental); right vetricular myocardial mass (r=0.97 in vitro; r=0. 96 in vivo); myocardial mass of in-farction(r=0. 95 in experimental); size of atrial septal defect(r=0. 95 -0. 97 in experimental; r=0. 94-0. 98 in patients); size of ventricular septal defect(r=0. 95 -0. 96 in experimental; r=0. 96 -0. 99 in patients); size of cardiac tu-mors; location, segment and extention of mitral prolapse; volume of mitrai valves; volume of mitrai regurgitant jets, volume of aortic re-gurgitant jets; size of arteries and stents as well as the gaps between stent and arterial wall. The results show that 3 -D is a very useful technigue in quantitative measurement of cardiovascular diseases.
