Prior distributions used for Bayesian IVIM model fitting

Parameter	Distribution	Distribution parameters (other than limits)${}^{\mathrm{a}}$	Distribution limits (lower–upper)
D	Lognormal	μ = −6, σ = 1	0‐5 $\mathrm{\mu }{m}^2$/ms
f	Uniform	—	0‐1
$D^{*}$	Lognormal	μ = −3.5, σ = 1	0‐1000 $\mathrm{\mu }{m}^2$/ms
$S_0$	Uniform	—	0‐2 $S_{\max }^{\mathrm{b}}$

${}^{\mathrm{a}}\mu$ and σ are given in numbers converting to ${\text{mm}}^2$/s.

${}^{\mathrm{b}}{S}_{max}$ is the maximum measured signal.
