Fig. 1A —Diagrammatic illustrations of relationships of relaxation times of
liver tissue and main magnetic field strength (B0). Note that data
of de Bazelaire et al. [1] are
within confidence interval obtained by Bottomley et al.
[7] even though 3.0-T data
point is outside scope of article by Bottomley et al. Graph shows relationship
of longitudinal relaxation time, T1, of liver tissue and main magnetic field
strength. Data are shown from meta-analysis based on more than 800 study
samples performed by Bottomley et al.
[7] (
), together with
data based on six volunteers acquired by de Bazelaire et al.
[1] (
). Note nonlinear
increase of T1 of liver tissue with main magnetic field strength. Also shown
are nonlinear regression (solid line) and 95% confidence interval for
data (dashed lines) as described by Bottomley et al.
