Abstract:
Objective To investigate the evidence of effective therapy of transient ischemic attacks (TIA) through the study on the regional cerebral blood flow and the function of neurocyte in the symptom free phase Methods Forty one patients with TIA and 45 controls were examined by single photon emission computed tomography (SPECT), computed tomography cerebral perfusion imaging (CTPI) and the positron emission tomography (PET) Results The abnormal rate of SPECT examination was 95 1%, and abnormal perfusion rate of CTPI was 63 4% These results revealed that there were reduction of regional cerebral blood flow in above half of TIA patients SPECT showed abnormal in some patients with normal CTPI show, which was possibly because of abnormal function of neurocyte, and the latter was confirmed by PET Conclusion Patients with TIA should have not only abnormal function of neurocyte, but also have reduction of regional cerebral blood flow in the intermittent phase The therapy of TIA should be emphasized in order to prevent TIA relapse and the occurrence of irreversible changes
