摘 要:Objective To evaluate the utility of computed tomography perfusion(CTP)both at admission and during delayed cerebral ischemia time-window(DCITW)in the detection of delayed cerebral ischemia(DCI)and the change in CTP parameters from admission to DCITW following aneurysmal subarachnoid *** Eighty patients underwent CTP at admission and during *** mean and extreme values of all CTP parameters at admission and during DCITW were compared between the DCI group and non-DCI group,and comparisons were also made between admission and DCITW within each *** qualitative color-coded perfusion maps were ***,the relationship between CTP parameters and DCI was assessed by receiver operating characteristic(ROC)*** With the exception of cerebral blood volume(P=0.295,admission;P=0.682,DCITW),there were significant differences in the mean quantitative CTP parameters between DCI and non-DCI patients both at admission and during *** the DCI group,the extreme parameters were significantly different between admission and *** DCI group also showed a deteriorative trend in the qualitative color-coded perfusion *** the detection of DCI,mean transit time to the center of the impulse response function(Tmax)at admission and mean time to start(TTS)during DCITW had the largest area under curve(AUC),0.698 and 0.789,*** Whole-brain CTP can predict the occurrence of DCI at admission and diagnose DCI during *** extreme quantitative parameters and qualitative color-coded perfusion maps can better reflect the perfusion changes of patients with DCI from admission to DCITW.
