Fig. 1From: Synthetic hematocrit derived from the longitudinal relaxation of blood can lead to clinically significant errors in measurement of extracellular volume fraction in pediatric and young adult patientsLinear regression fit of measured vs synthetic Hct and ECV for published model. Poor regression fit to the published model (a) with a bias of 2.2% on Bland-Altman analysis (b). However at the mid-free wall, the regression fit for ECV is substantially better (c) with an expected inverse bias on Bland-Altman analysis due to the bias seen in the Hct (d). Dashed line in A and C represents line of identity. For Bland-Altman plots, solid line represents mean difference and dashed lines (B and D) are ±1.96SDBack to article page
