摘要/Abstract

摘要： 目的：探讨脑CT灌注成像联合CT血管造影（CTA）成像对颈性眩晕病因的诊断价值。方法：采用西门子64排螺旋CT对46例颈性旋晕患者进行头颅CT平扫、CT灌注成像（CTPI）及CTA检查。结果: ①CT平扫显示脑梗塞4例，未见异常42例; ②CTPI脑血流灌注正常19例，异常27例；③CTA46例颈性眩晕患者中有21例存在椎动脉狭窄。18例患者脑血管存在局限性狭窄或部分血管未显影，未见异常7例;④CTPI显示的17例脑梗塞前期患者在CTA中均显示有相应血管狭窄或闭塞。结论:CTPI联合CTA能够清晰的显示椎基底动脉及脑供血情况，是判断颈性眩晕病因及脑缺血严重程度的一项较实用的客观可靠的检查手段。

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.
