Abstract:
Objective To assess the value of 16-slice spiral CT perfusion in the diagnosis of hyperacute cerebral infarction.Methods Routine and perfusion CT of brain were performed in 20 cases suspected with hyperacute cerebral stroke within 6 hours of symptom onset,the images of plain scan,rCBV,rCBF,MTT and TTP were observed and evaluated. All cases were followed-up with CT after one week.Results Ischemic lesions were found in routine CT in 5 cases,15 cases had negative results at routine CT, and ischemic lesions were showed in all of them by perfusion CT images.rCBV,rCBF distinctly decreased, MTT and TTP obviously prolonged in infarction area,and rCBF decreased, MTT and TTP prolonged and rCBV was normal or up lightly in the penumbra area. The infarction lesions were detected in 15 cases by follow-up CT.Conclusion 16-slice spiral CT perfusion in diagnosis of hyperacute cerebral infarction may be a valuable tool in predicting clinical prognosis.
