| 目的 采用实时三维超声心动图(RT-3DE)及MRI对右心室容量及收缩功能进行对比分析。方法 采用RT-3DE、MRI法对30例心血管疾病患者的右心室功能进行分析,测量右心室舒张末期容积(EDV)、收缩末期容积(ESV)及射血分数(RVEF),并比较相关性。采用RT-3DE对98名正常成人的右心室容量及射血分数进行测量。结果 RT-3DE获得的右心室EDV、ESV值明显小于MRI(P均＜0.05),而两者的RVEF值差异无统计学意义。两种方法测量的EDV、ESV、RVEF值均具有较好的相关性(rEDV=0.81,rESV=0.84,rEF=0.70,P均＜0.05)。RT-3DE测得98名正常成人右心室EDV为(92.47±31.83)ml,ESV为(40.69±17.42)ml,RVEF为(56.47±6.65)%;正常成人女性的右心室EDV小于男性(P＜0.05),而ESV及RVEF在两性间差异均无统计学意义(P均＞0.05)。不同年龄组的正常成人右心室EDV、ESV、RVEF差异均无统计学意义(FEDV=3.06,FESV=2.63,FRVEF=0.11,P均＞0.05)。结论 RT-3DE可作为观测右心室收缩功能的一种筛查和初步替代MRI的方法。 |

| Objective To compare right ventricular (RV) volume and systolic function by real time three-dimensional echocardiography (RT-3DE) and MRI. Methods Thirty patients with heart and vascular diseases underwent RT-3DE and MR examination simultaneously. End-diastolic volume (EDV), end-systolic volume (ESV), and ejection fraction of RV (RVEF) were acquired. Then the correction of results of these two methods was analyzed. Meanwhile, RV systolic function of 98 normal adults was analyzed with RT-3DE. Results EDV and ESV acquired with RT-3DE were less than those acquired with MRI (both P＜0.05), but no statistical difference of RVEF was found. EDV, ESV and RVEF measured with RT-3DE had good correlation with those measured with MRI (rEDV=0.81, rESV=0.84, rEF=0.70, all P＜0.05). RV systolic function of 98 normal adults in RT-3DE were acquired, i.e. EDV (92.47±31.83)ml, ESV (40.69±17.42)ml, RVEF (56.47±6.65)%. EDV of normal women was less than that of normal men (P＜0.05), but ESV and RVEF had no statistical difference between two sexes. In normal adults, EDV, ESV and RVEF had no statistical difference among different ages (FEDV=3.06, FESV=2.63, FRVEF=0.11, all P>0.05). Conclusion RT-3DE can be used as a screening and preliminary alternative technique of MRI in assessing right ventricular systolic function. |
