Diagnostic Value Of CT Perfusion Combined With CT Angiography In Cervical Vertigo

Objective: To study the diagnostic value of the CT perfusion combined with CT angiography for the causes and pathogenesis in patient with cervical vertigo Methods: 46 patients with cervicalvertigo were examined by conventional CT ,CTPI and CTA .Results: (1) The arterial total length of 92vertebrobasilar arteries were displayed in varies reconstruction images, including 26 normal arteries, 66 abnormal arteries, and the later ones are 31 mild, 23moderate, and 12 severe vertebral and / or basilar artery stenosis respectively, including 5 stenosis with kinkings and 7stenosis with calcified plaques. On the other hand, 8 hypogenesis were revealed, and 6 kinkings were detected. The parts of atlas of vertebral arteries were not showed excellent in 8 arteries by VR. All vertebrobasilar arteries were showed total length with excellent results by AVA. (2) All cases in the control group show normal vertebroba- silar artery image and normal adjacent anatomic structures. (3) There are significant differences between mild group, moderate group, severe gro- up and the control group. A significant difference is also found between moderate group, severe group and mild group. (all p<0.05)Conclusion: By combining MSCT scanning with suitable postprocessing techniques, MSCTA can well display normal or abnormal vertebral and basilar arteries, as well as adjacent anatomic structures. It has an important clinical significance for the diagnosis of vertebrobasilar artery ischemia vertigo.Significance: MSCTA is a noninvasive method. It enables accurate evaluation vertebral and basilar arteries, and the relation between stenosis of vertebral arteries and the bony structures could be well depicted. When displaying sclerosis it can well depict the pressed location, etiology and degree of press of vertebrobasilar artery. Therefore, it has an important clinical significance for etiology study, prognosis judgement and guiding therapy of vertebrobasilar artery ischemia vertigo. And it provides a new pathway to evaluate vertebrobasilar artery noninvasively. As for convenience, feasibility and availability, MSCTA is an important examination method for the diagnosis of vertebrobasilar artery ischemia vertigo.
