| 摘 要： | 目的在心室腔变形情况下,以注水法实测值为“金标准”,探讨实时三平面成像法(Tri-plane)测量左心室容积的准确性。若Tri-plane法可以准确测量左心室容积,则以其测值为标准,检验双平面Simpson法(2DE-Simpson)测量左心室容积的准确性。方法①在8个模拟左心室室壁瘤的橡胶水囊中(A组),应用Tri-plane法同步采集其三个互成60°角的长轴观图像,手动勾画上述切面观内膜边界测量左心室容积。以注水法实测容积作为“金标准”,将Tri-plane法容积测值与之比较。②在16个存在左室节段性室壁运动异常(RWMA)冠心病患者中(B组),应用Tri-plane法同步采集其心尖四腔观、心尖二腔观及心尖左室长轴观图像,手动勾画上述三个切面观心内膜边界测量左室舒张末期容积(LVEDV)和收缩末期容积(LVESV);同时应用2DE-Simpson法测量LVEDV和LVESV。以Tri-plane法所测容积值作为标准,将2DE-Simpson法容积测值与之比较。结果A组,Tri-plane法容积测值和实测左室容积呈高度正相关(r=0.982),且两者差异无统计学意义(P>0.05)。B组,2DE-Simpson法所测LVEDV和LVESV均低于Tri-plane法测值,其差异均有统计学意义(均P<0.05)。结论在心腔变形情况下,Tri-plane法可准确地测量左心室容积;而2DE-Simpson法测量左心室容积会造成容积的低估。Tri-plane法在容积测量方面较2DE-Simpson法更具优势。
