Abstract: Objective: To study the value of CT perfusion combined with CT angiography in diagnosis of cervical vertigo. Methods: Conventional CT, CTPI and CTA examination was performed on forty-six patients with cervical vertigo. Results: (1) With conventional CT, 4 had cerebral infarction and 42 did not. (2) With CTPI, 27 had hypoperfusion and 19 did not. (3) With CTA, 21 had stenosis of vertebral arteries and 18 had stenosis of arteries, and 7 did not. (4) 17 patients with prophase of infarct proved by CTPI had vessel stenosis or occlusion by CTA.Conclusion: CTPI combined with CTA is capable of accurate evaluation of vertebrobasilar artery and cerebral artery and is reliable for cervical vertigo.
