Notes
Left ventricular end diastolic volume
Please be aware that the inline VF results are fully automated without any expert quality control. Caution is advised to use results without any visual quality control or linear bias correction as recommended in the following paper: Fully-automated left ventricular mass and volume MRI analysis in the UK Biobank population cohort: evaluation of initial results. Suinesiaputra, A. et al. Int J Cardiovasc Imaging. 2018 (https://dx.doi.org/10.1007%2Fs10554-017-1225-9). Expert research groups are performing CMR analysis with quality control and these will be available in the Returns Catalogue.
