Abstract

Objective To explore the clinical application of 64-slice spiral CT angiography(CTA) and DSA in intracranial and extracranial artery stenosis.Methods 152 patients were clinically diagnosed as cerebral infarction or TIA.They were examined by 64S CTA and DSA.The results of CTA were compared with that of DSA.The sensitivity and specificity of CTA and DSA of intracranial and extracranial artery were figured out.Results The diagnostic sensitivity and specificity of basilar artery were 73.9% and 85.4%.The diagnostic sensitivity and specificity of middle cerebral artery were 80.7% and 83.6%.The diagnostic sensitivity and specificity of internal carotid artery open were 94.6% and 97.4%.Conclusion 64S CTA can demonstrate the changes of intracranial and extracranial artery seenosis.It can replace DSA in certain field.
