To investigate the relation between the quantitative assessment of magnetic resonance imaging (MRI) features and the correlation with histology and functional recovery by using the rabbit sciatic nerve crush model. ⋯ The SIR of injured nerve at distal portion increased on MRI. The evolution of SIR after injury was correlated with the degeneration and regeneration of nerve and the function recovery of lower extremities. Assessment of peripheral nerve injury by using SIR could reveal acute nerve injury, as well as aid in monitoring the recovery process. The pathophysiological basis for the SIR is predominantly the results of axon breakdown and myelin regeneration
