Abstract Objective: To investigate the value of three-dimensional real-time echocardiography in the assessment of right ventricular global function, in comparison with MRI. Methods: Thirty healthy volunteers (16 male, 14 female, average age 49±3.2 years old) underwent three-dimensional echocardiography and breath-hold MRI. Using iE33 medical Philips system, the end-diastolic volume(EDV), end-systolic volume(ESV), stroke volume(SV) and ejection fraction(EF) were determined by TomTec 4D RV-analysis software. The results from echocardiography were compared with those from MRI using Pearson correlation test and Bland-Altman-plot. Results: Mean EDV((143.5±23.2) mL）, ESV((68.4±19.2) mL), SV((78.1±11.7) mL) and EF((51.2±5.6)%) determined by echocardiography correlated well with those by MRI((147.5±26.8) mL(r=0.947), (63.2±15.9) mL(r=0.909), (78.8±15.0) mL(r=0.788), (55.2±7.7)%(r=0.627). A strong correlation between three-dimensional real-time echocardiography and MRI was also found in Bland-Altman-plot. Conclusion: Three-dimensional real-time echocardiography can assess right ventricular global function accurately. It is a valuable method for evaluating cardiac function.
