摘要
目的评价氙气-CT(Xe-CT)对慢性脑供血不足的诊断价值。方法对15例临床初诊为慢性脑供血不足的患者进行TCD等血管检查及Xe-CT脑血流检测,以明确诊断。结果9例患者Xe-CT检查提示存在局部或全脑血流量减低,可明确诊断为慢性脑供血不足,6例患者Xe-CT脑血流检查未见异常,还需结合其它检查,以进一步明确诊断。结论Xe-CT能够判定患者脑缺血区域、范围及程度,可以为慢性脑供血不足的诊断提供可靠依据。
Objective To evaluate the effect of Xenon-CT in diagnosis of chronic cerebral circulation insufficiency. Methods 5 patients in study who were suspected with chronic cerebral circulation insufficiency were all from out-patients. The Xenon-CT examination was undertaken to value their cerebral blood flow for diagnose. Results 9 patients showed cerebral blood flow（CBF） decrease in parts or the whole brain,which strongly supported the diagnosis of chronic cerebral circulation insufficiency. The other 6 patients had no significant change of CBF, and they deserved further study on etiology and diagnosis. Conclusion Xenon-CT could determine patients＇ cerebral ischemic site,area and serious degree. It pro- vides a credible evidence to the diagnosis of chronic cerebral circulation insufficiency.
