Abstract

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.
