The value of CT angiography in intracranial and cervical arteries in patients with cerebrovascular disease

Objective To explore the clinical application value of 64-slice computed tomography angiography in cerebrovascular diseases. Methods 33 cases of cerebral infarction, 46 cases of TIA, 9 cases of subarachnoid hemorrhage and 5cases of cerebral hemorrhage , 3cases of intraeranial vascular malformations were examined with 64-slice spiral CTA. Images finding of cerebral vessels were evaluated by volume reconstruction maximum intensity projection,and multiplanar reconstruction .Results The 73 cases of patients were displayed single or multivessel , multisections son -hard atheromatous plaque formation that result in angiostenosis or blockages, 5cases of vascular variation, 7 cases of single vertebral artery maldevelopment, 12cases of aneurysma or aneurysmal dilatation, 3 cases of vascular malformation.Conclusion The CT angiography in intraeranial and cervical arteries can displayed the vessel in encephalic, vertebral artery, basal arteries. Willis circle, and precerebral artery, middle cerebral artery, posterior cerebral artery, including Level 3 above brancho It is dependable for diagnosis the Soft -hard atheromatous plaque , vascular variation, vertebral artery maldevelopment, aneurysma or aneurysmal dilatation, vascular malformation and Narrow degree of vessel
