[Assessment of right ventricular function by 64-slice multi-detector CT].

Objective: To evaluate the accuracy of using 64-MDCT to assess right ventricular function.
Methods: The ventricular function of 32 adult volunteers were assessed by ECG-gated 64-MDCT and MRI, which included right ventricular end-diastolic and end-systolic volume, stroke volume, and ejection fraction. Consistency between the two modalities was tested with Bland and Altman analysis and Pearson's correlation.
Results: No significant differences were found in calculated RV volumes and EF between the two modalities (P = 0.29 to 0.66). Consistency was achieved in RV-EDV [(0.6 +/- 4.9) mL; r = 0.98)], RV-ESV [(-0.6 +/- 3.4) mL; r = 0.97], RV-SVC [(0.9 +/- 5.6) mL; r = 0.93, and RV-EFC (1.0 +/- 3.9) mL; r = 0.88].
Conclusion: ECG-gated 64-MDCT can accurately assess RV function.
