The LEAP investigators evaluated their cohort of patients with severe lower extremity trauma and found that the time from injury to debridement was not predictive of infection6.

Objective To discuss the value of Time-Resolved Imaging of Contrast Kinetics in the diagnosis of lower extremity diseases.

Result:Unaffected side of hemiplegic patient and normal lower limb were notable different in time parameters, space parameters and knee joint angle(P<0.01).
