PDFAbstract
Objective To evaluate the application value of MSCT scan, head and neck CTA and cerebral perfusion (CTP) in patients with TIA. Methods 30 cases meeting the standards of TIA clinical diagnosis were involved in this study, in which all patients underwent head and neck CT scan, CTA scan and cerebral perfusion imaging (CTP) to obtain the imaging data. Results Eight patients in ten cases with TIA related to the vertebral basal artery system, were detected with cerebral perfusion abnormalities, while seven patients with atheromatous plaques and luminal stenosis in CTA. 15 patients in 20 cases with TIA related to the Internal carotid artery system were detected with cerebral perfusion abnormalities and 14 patients were detected with atheromatous plaques and luminal stenosis in CTA. Conclusion With the help of 64-layer spiral CT we can quickly discover the stenosis or block in the arterys of head and neck, analyize the correlation factors of soft plaques, and get further information about the cerebral hemodynamic changes. We think that it has great clinical significance not only in predicting the risk of stroke, but also in early diagnosis of TIA patients and their following treatment.
