背景资料：超声心动图衍生的线性尺寸提供了直接的指标右心室（RV）结构，但没有系统地比较心脏磁共振（CMR）的RV容量。方法：超声心动图和CMR之间的冠状动脉疾病成像患者通过前瞻性（90%）和回顾性（10%）注册解释。对于超声心动图，在心尖四腔（基础RV宽度、中间RV宽度和RV长度）、胸骨旁长轴（近端RV流出道[RVOT]）和短轴（远端RVOT）视图中测量美国超声心动图学会推荐的RV尺寸。对于CMR，RV舒张末期容积和RV收缩末期容积进行了定量使用边界planimetry.Results：二百七十二例患者进行了超声心动图和CMR在一个狭窄的间隔（0.4 +/- 1.0天）;完全收购所有美国超声心动图协会推荐的尺寸是可行的98%。CMR显示右室扩张患者与非右室扩张患者的所有超声心动图参数均不同（P <0.05）。基础RV宽度（r = 0.70）、近端RVOT宽度（r = 0.68）和RV长度（r = 0.61）与CMR上的RV舒张末期容积相关性最高;收缩末期尺寸相关性相似（分别为r = 0.68、r = 0.66和r = 0.65）。在多变量回归中，基础RV宽度（回归系数= 1.96/mm; 95%CI，1.22-2.70; P <0.001）、RV长度（回归系数= 0.97; 95%CI，0.56-1.37; P <0.001）
Background: Echocardiography-derived linear dimensions offer straightforward indices of right ventricular (RV) structure but have not been systematically compared with RV volumes on cardiac magnetic resonance (CMR).Methods: Echocardiography and CMR were interpreted among patients with coronary artery disease imaged via prospective (90%) and retrospective (10%) registries. For echocardiography, American Society of Echocardiography-recommended RV dimensions were measured in apical four-chamber (basal RV width, mid RV width, and RV length), parasternal long-axis (proximal RV outflow tract [RVOT]), and short-axis (distal RVOT) views. For CMR, RV end-diastolic volume and RV end-systolic volume were quantified using border planimetry.Results: Two hundred seventy-two patients underwent echocardiography and CMR within a narrow interval (0.4 +/- 1.0 days); complete acquisition of all American Society of Echocardiography-recommended dimensions was feasible in 98%. All echocardiographic dimensions differed between patients with and those without RV dilation on CMR (P < .05). Basal RV width (r = 0.70), proximal RVOT width (r = 0.68), and RV length (r = 0.61) yielded the highest correlations with RV end-diastolic volume on CMR; end-systolic dimensions yielded similar correlations (r = 0.68, r = 0.66, and r = 0.65, respectively). In multivariate regression, basal RV width (regression coefficient = 1.96 per mm; 95% CI, 1.22-2.70; P < .001), RV length (regression coefficient = 0.97; 95% CI, 0.56-1.37; P
