摘　　要：目的探讨全身成像三维量化(GI3DQ)法直接测量二尖瓣反流束体积用以评估二尖瓣反流(MR)体积的可行性和准确性。方法:93例MR患者,分两组:偏心性MR:52例;中心性MR:41例。GI3DQ法直接测量MR体积;Doppler法计算的MR体积作为参考标准。结果:偏心性与中心性MR组:Doppler计算MR体积与GI3DQ测量MR体积相关性分别为:r=0.77,r=0.81;一致性分析:偏心性MR组,GI3DQ法较Doppler法平均低估12.19ml,P<0.05;中心MR组,GI3DQ法较Doppler法平均低估1.34ml,P>0.05。结论:与Doppler法相比,偏心性MR组,GI3DQ法低估MR体积;中心性MR组,两种方法未见明显差异。Objective： To evaluate feasibility and accuracy of mitral regurgitant volume （MRvol） by quantification of mitral regurgitation （MR）jet volume with GI3DQ method. Method： A total of 93 patients with MR were included. The MR patients were divided into central MR group （n=41） and eccentric MR group （n=52）. MRvol was assessed using GI3DQ method and quantitative Doppler method was used as reference method. Result： In eccentric MR group, MRvol measured by GI3DQ method showed good correlation with MRvol measured by quantitive Doppler method （r = 0.77） with a lower underestimation （mean difference =- 12.19ml,P 〈 0.05）.In central MR group, the correlation of MRvol measured by GI3DQ method and by quantitative Doppler method was better（r = 0.81） with no significant difference （mean difference = - 1.34ml, P 〉0.05）, Conclusion： Quantification of central MRvol with GI3DQ was accurate as compared with MRvol by quantitative Doppler method, but in eccentric MR group, the GI3DQ method underestimated MRvol.
