Objective     To investigate the diagnostic value of 128-slice spiral CT angiography in cervical-cerebral vascular diseases.     Methods    The data of 981 patients who received 128-slice spiral CT cervical-cerebral angiography in our hospital from March 2009 to September 2010 were analyzed retrospectively.     Results     Among the 981 cases

89 cases were identified with intracranial aneurysm

25 cases with intracranial arteriovenous malformations

524 cases with cervical-cerebral angiostenosis (there were 195 stenoses in internal carotid

183 stenoses in the initial segment of internal carotid

75 stenoses in the initial segment of the left subclavian artery

73 stenoses in the initial segment of vertebral artery

53  stenoses in common carotid artery

and 3 cases of moyamoya disease)

3 cases had sigmoid sinus thrombus

3 cases had cavernous sinus fistula

and 78 cases had variation. The left 259 cases showed normal manifestation. Positive rate was 73.59% (722/981) in this study.     Conclusion     128-slice spiral CT angiography has the great advantages in the diagnosis of cervical-cerebral vascular diseases

such as high effectiveness

non-invasiveness

sound diagnostic value. It also can evaluate the risk of diseases and help select appropriate treatment strategies.
