The preliminary research of CT perfusion imaging in intraaxial ischemic disease

LIU Xiang, DAI Jianping, SUN Bo, et al Department of Neuroradiology, Beijing Neurosurgical Institute, Beijing 100050  
Objective To evaluate the application of CT perfusion in intraaxial disease Methods 34 cases intracranial ischemic disease (including 24 cases with stroke, 10 cases with postoperation ischemic lesions) were analyzed 19males, 15 females 34 cases with CT imaging and CT perfusion imaging, 28 cases with MRI examination, 6 cases with DSA snd SPECT examination Results There were 41 ischemic lesions on CT perfusion imaging, conformed by followup CT, MRI and SPECT images While only 30 on regular CT images 40 lesions with PT (longer peak time) and MTT (mean transit time), and lower RF (relative flow ) than opposite's, P00001 Only one lesion-2 weeks after stroke onset with shorter PT and MTT and higher RF Conclusions Combined with regular CT and MRI images, CT perfusion imaging not only is useful in demonstrating the hyperacute ischemic stroke, but also can show the hemodynamic changes of intraaxial ischemic lesions caused by moya moya disease and craniotomy.
