Abstract:
Objective To explore the application value of 320-slice volume CT in detecting the cerebral transient ischemic attack (TIA). Methods One-stop CT scan was performed at intermission of onset on 11 patients with cerebral TIA; the data of plain CT scans, CT angiography (CTA) and whole brain perfusion on these patients were collected. Analysis by synthesis was performed on these imaging data. Results No lesions responsible for the attack were found in the brains of 11 patients with TIA under plain CT scan; 3 of them performed MRI did not have positive results. CTA indicated that the vascular networks in 10 patients were obviously sparse in the region of lesions responsible for the attack;the corresponding vessels in 8 of them became thin; both vascular thrombosis and compensatory angiogenesis occurred in 2 patients. The cerebral perfusion indicated that perfusion areas corresponding to clinical symptoms displayed delayed mean transit time and time to peak level in these 11 patients.Decreased regional cerebral blood flow was noted in 5 patients and regional cerebral volume increased mildly in 3 patients. Conclusion The 320-slice-volume CT perfusion imaging can obtain the information about whole brain perfusion, routine CT scan and CTA by injecting a kind of contrast medicament for only one time, thus can assess the ischemic cerebrovascular disease comprehensively.
