摘　　要：目的比较超声与磁共振（MRI）对扩张型心肌病（DCM）患者心功能参数测量差异。方法选择41例临床诊断为DCM的患者，使用MRI及超声[分别在心脏垂直长轴位（VLA）、水平长轴位（HLA）和短轴位（SA）]两种方法检测患者的心功能指数，包括左心室舒张末容积（LVEDV），左心室收缩末期容积（LVESV）、左室射血分数（LVEF）及每搏输出量（SV），对2种方法获得的数据进行比较和相关分析。结果①LVEDV和LVESV值比较：MRI测得LVEDV值[（262．6±117．0）m1]和LVESV值[（196．4±109．8）m1]均比超声测量值高[（211．4±90．6）、（216．5±71．5）、（219．1±80．1）ml；（153．3±76．1）、（153．9±54．1）、（157．0±61．1）ml，P均〈0．05]。②SV和LVEF值比较：MRI测得sV值[（66．2±21．3）m1]高于超声VLA[（58．1±14．4）ml，P〈0．05]；MRI测得LVEF值[（25．2±7．2）％]低于超声的HIJA、SA所测值[（28．9±6．1）％、（28．3±6．1）％，P均〈0．05]。③超声SA测得LVEDV、LVESV值与MRI测量值存在相关性（r=0．785、0．653，P均〈0．05）；超声VIA测得LVEF值和MRI测量值存在相关性（r=0．690，P〈0．05）；超声HLA、SA测得SV值和MRI测量值存在相关性（r=0．734、0．701，P均〈0．05）。结论超声与磁共振在扩张型心肌病心功能不同参数测量的准确性和可靠性存在差异，需区别对待。Objective To compare the difference of echocardiography and magnetic resonance imaging （MRI） in measurement of cardiac function in patients with dilated cardiomyopathy （DCM）. Methods Totally 41 patients with DCM underwent echocardiography and MRI to measure cardiac function, the parameters included left ventricular end-diastolic volume （LVEDV）, end systolic volume （LVESV）, left ventricular ejection fraction （LVEF） and stroke volume （SV）. The vertical long axis （VLA）, horizontal long axis （HLA） and short axis （SA） of heart were measured by echocardiography. The differences of echocardiography and MRI were compared by linear regression and linear correlation. Results （1）The value of LVEDV and LVESV obtained by the two methods： the value of LVEDV [（262.6 ± 117.0） ml] and LVESV [（196.4 ±109.8） ml] obtained by MRI were higher than those of echocardiography [（211.4 ± 90.6）, （216.5 ± 71.5）, （219.1 ± 80.1） ml; （153.3 ± 76.1）, （153.9 ± 54.1）, （157.0 ± 61.1） ml, all P 〈 0.05]. （2）The value of SV and LVEF obtained by the two methods： the value of SV[（66.2 ± 21.3） ml] obtained by MRI was higher than that of echocardiography VLA [（58.1 ± 14.4） ml, P 〈 0.05]. The value of LVEF [（25.2 ± 7.2）%] obtained by MRI was lower than those of echocardiography HLA and echocardiography SA [（28.9 ± 6.1）%, （28.3± 6.1）%, all P 〈 0.05]. （3）The value of LVEDV and LVESV obtained by echocardiography SA were associated with those obtained by MRI （r = 0.785, 0.653, all P 〈 0.05）. The value of LVEF obtained by echocardiography VLA was associated with it obtained by MRI （r = 0.690, P 〈 0.05）. The value of SV obtained by echocardiography HLA and echocardiography SA were associated with those obtained by MRI （r = 0.734, 0.701, all P 〈 0.05）. ConclusionThere are differences in accuracy and reliability using echocardiography and MRI when measuring dilated cardiomyopathy heart function, which must be treated differen
