Objective To investigate the correlation of brain perfusion computed tomography(CT) results and cerebral perfusion pressure(CPP) in patients with severe head trauma.MethodsPerfusion CT results of 50 patients with head trauma were analyzed,who were divided into two groups of T(28 cases,severe head trauma with abnormal CT findings during admission) and C(22 cases,head trauma with normal CT findings during admission).The patients underwent perfusion CT and MAP and ICP were measured at the same time,by which CP...
