The change in Hct and ECV between before and after a CMR examination. a) The mean Hct (black bars) and mean ECV (grey bars) before and after the CMR examination. Error bars indicate standard deviation. b) Individual change in Hct (filled circles) and ECV (open circles) for all 43 subjects. Note that all patients decreased in Hct after the examination compared to before except for two patients who remained the same. **** indicates p < 0.001. CMR = cardiovascular magnetic resonance, ECV = extracellular volume fraction, Hct = hematocrit
