Relationship between T2*-weighted signal change and heart rate and blood pressure change during the phase of positive T2*-weighted signal change in PAD. The value of $\overline{\mathrm{\Delta }\mathrm{S}\mathrm{I}},\overline{\mathrm{\Delta }\mathrm{H}\mathrm{R}}$ and $\overline{\mathrm{\Delta }\mathrm{M}\mathrm{A}\mathrm{P}}$ from each PAD patient were obtained by averaging the corresponding measurements over the time period with positive T2*-weighted signal.
