Fig. 6From: Diffusion tensor imaging and electrophysiology as robust assays to evaluate the severity of acute spinal cord injury in ratsCorrelation analyses of the values of FA and AD with MEPs. FA and AD value were significantly correlated with MEPs on day 7(a, c) and 14 (b, d). Blue dot represented rats with moderate SCI and green square represented those with severe SCI.
