title: Is cardiac CT a reproducible alternative for cardiac MR in adult patients with a systemic right ventricle?
abstract: OBJECTIVE
  20 % of patients with a systemic RV are pacemaker dependent, and unsuitable to undergo cardiac magnetic resonance (CMR). Multidetector row computed tomography (MDCT) could provide a reproducible alternative to CMR in these patients. The aim of this study was to compare variability of MDCT with CMR.
  
  
  METHODS
  Thirty-five patients with systemic RV underwent either MDCT (n = 15) or CMR (n = 20). Systemic RV volumes and ejection fraction were obtained, and intra- and interobserver variability for both modalities were assessed and compared.
  
  
  RESULTS
  We found the intra- and interobserver variability of volumes and function measurements of the systemic RV obtained with MDCT to be higher compared with those obtained with CMR. However, these differences in variability were not significant, the only exception being the interobserver variability of systemic RV stroke volume.
  
  
  CONCLUSIONS
  MDCT provides a reproducible alternative to CMR for volumes and function assessment in patients with a systemic RV.
