摘　　要：目的 探讨全身成像三维量化（GI3DQ）法定量评估主动脉瓣反流体积（AR-Vol）的可行性和应用价值.方法 随机选取2014年2-10月在天津市胸科医院接受超声心动图检查的主动脉瓣反流（AR）患者102例.分为两组,其中偏心性组包含偏心性AR患者40例,中心性组包含中心性AR患者62例.用GI3DQ法直接测量AR-Vol;近端血流等速面（PISA）法测量AR-Vol作为参照标准.结果 （1）偏心性组GI3DQ法与PISA法测得AR-Vol分别为（44 ±11）、（48±10） ml;中心性组GI3DQ法与PISA法测得AR-Vol分别为（34±13）、（33±13） ml.（2）配对t检验示偏心性组两种测量方法的差异有统计学意义（P＜0.01）;中心性组两种测量方法的差异无统计学意义（P =0.202）.（3）偏心性组与中心性组GI3DQ法与PISA法测量AR-Vol相关系数分别为：r=0.835,r =0.913;一致性分析偏心性组两种方法差异有统计学意义（P =0.000 2）,中心性组两种方法差异无统计学意义（P=0.201 7）.结论 中心性AR时,GI3DQ法评估AR-Vol与PISA法相比可行且准确,可作为常规应用.Objective To investigate the feasibility and application value of AR-Vol measured by GI3DQ method directly.Methods One hundred and two patients with aortic regurgitation who underwent echocardiographic examination in Tianjin Chest Hospital from February 2014 to October 2014 were selected randomly and divided into two groups：the eccentric group included forty cases with eccentric aortic regurgitation;the central group included sixty and two cases with central aortic regurgitation.AR-Vol were directly measured by GI3DQ method,and then it was calculated by PISA method as the reference standard.Results （1） In the eccentric group,the AR-Vol measured by GI3DQ method and PISA method were respectively （44 ± 11） ml and （48 ± 10） ml.In the central group,the AR-Vol measured by GI3DQ method and PISA method were respectively （34 ± 13） ml and （33 ± 13） ml.（2） Paired t test analysis showed significant difference in two methods of the eccentric group （P 〈 0.01）;no significant difference was found in two methods of the central group （P =0.202）.（3） The correlation coefficients of the AR-Vol measurement by GI3DQ method and PISA method are relatively in two groups：r =0.835,r =0.913;consistency analysis showed differences between the two methods of the eccentric group had statistical significance,and differences between the two methods of the central group had no statistical significance.Conclusion In the central aortic regurgitation,AR-Vol measured by GI3DQ method is feasible and accurate compared with the PISA method,which can be used for routine application.
