Imaging Features of CT Perfusion in Intracerebral Hemorrhage Patients

SUN Xiangrong,GUO Fuqiang,TAO Keyan,et al.The Radiology Department of Sichuan Province People's Hospital,Chengdu 610072,Sichuan,P.R.China  
Objective To investigate the computered tomography perfusion (CTP) features in intracerebral hemorrhage(ICH) patients.Materials and Methods 27 patients with supratentorial ICH undergone CTP at different time after onset of ICH (from 5h to 2 weeks) and the imaging features of CTP were observed.Results The time density curves(TDC) of superior sagittal sinus were stable,which could reflect the overall intracranial perfusion of ICH patients.The size of perfusion deficit area was between that of edema and that of hematoma and edema.The deficits were more evident on the AP orientation than that on the left-right orientation,especially on a certain direction in the basal ganglia area.All the parameter maps were concentrically distributed and gradually improved from the core to the periphery.The perfusion deficit band were existed surround the haematoma.The perfusion was obviously reduced in the area of hemorrhage complicated with hydrocephalus.The cerebrovascular malformation could be displayed on MIP or on parameter maps.Conclusion The haemodynamic changes in ICH patients can been detected by CTP.Ischemic lesions exist arrioud the hematoma,which is caused by the compression of the heamatoma and other factors.The reduced perfusion secondary to hydrocephalus can be detected.CTP can give a clue to make diagnosis of the cause and the style of the ICH.
