title: [Assessment of right ventricular function by 64-slice multi-detector CT].
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].
  
  
  CONCLUSIONS
  ECG-gated 64-MDCT can accurately assess RV function.
