Figure 5. Graph shows time dependence of (SIpost - SIpre) in the ischemic leg (
) and the normal leg (
) 3 months after ischemia induction (mean ± SEM). The time range was 0-128 seconds. 
= Three months was significantly different from the control (paired t test; P < .05). * = Three months was significantly different from the control (paired t test; P < .01). The enhancement was still substantially higher in the affected area, as compared with that in the contralateral leg.
