Patients with ICH are sometimes treated with surgical evacuation. However, the efficacy of surgery remains unclear for recovery of motor function. We assessed the relationship between motor function outcome and sequential change of FA in patients, to explore whether motor function outcome can be predicted in the early phase. The FA values of the cerebral peduncle on day 3 could predict the motor function outcome on day 90. Patients with severe motor paresis and FA value of greater than 0.7 should be considered for surgical evacuation.
