    Abstract

    This study demonstrated the variability that can exist between two centres where different techniques are used for gated cardiac analysis. Despite both methods being adequately validated with low interobserver variation within each centre, significant statistical differences between centres were still demonstrated. These differences were largely due to problems in the definition of the atrio-ventricular boundary at end-systole which involved both operator and program decisions. Despite these statistical variations between centres, the clinical status of at least 90% of patients was judged the same at the two centres. If repeat studies are performed on the same patient at different hospitals, efforts should be made to exchange studies so that both can be analysed by the same program and operators. This is particularly recommended in situations where the results at the two centres is initially considered to be clinically different.
