Title: The practicality of cerebral ischemic penumbra applying dynamic 64-slice CT perfusion imaging
Abstract: Objective To explore the practicality of cerebral ischemic penumbra applying dynamic 64-slice CT perfusion imaging.Methods The perfusion parameters were measured at infarct core area,ischemic penumbra,and mirror area of theirs in 43 cases with ischemic penumbra.Results In ischemic penumbra of the 43 cases,mean transit time(MTT) and time to peak(TTP) delayed,cerebral blood flow(CBF) decreased,but cerebral blood volume(CBV) slightly decreased,normal or slightly increased.There were statistically significant difference on CBV,CBF,MTT and TTP between ischemic penumbra and infarct core area of the 43 cases.Between the 43 cases of ischemic penumbra and the control apteral corresponding region,there were statistically significant difference on CBF,MTT and TTP,but CBV was no significant difference.Conclusion Application of dynamic 64-slice CT perfusion imaging can make sure the area of the cerebral lesions and whether existence of ischemic penumbra.
