作者采用Diamox(乙酰唑胺)负荷脑血流SPECT法对脑主干动脉病变患者脑循环潜能进行评价,研究对象是MRI检查怀疑颈动脉或大脑中动脉病变、通过DSA以及多普勒检查确认其狭窄程度达70％以上的63例患者。并以24例无狭窄者为对照组来分析脑循环的潜能。63例中两侧颈内动脉狭窄或闭塞者18例,单侧颈内动脉闭塞14例,单侧颈内动脉狭窄18例,大脑中动脉狭窄或闭塞13例。做 The authors used Diamox (acetazolamide) -loaded cerebral blood flow SPECT to evaluate cerebral circulation potential in patients with primary arterial lesions. Subjects were suspected of carotid or middle cerebral artery lesions by MRI and were confirmed by DSA and Doppler examinations The degree of more than 70% of 63 patients. 24 patients without stenosis were used as control group to analyze the potential of cerebral circulation. In 63 cases, 18 cases of bilateral carotid artery stenosis or occlusion, unilateral carotid artery occlusion in 14 cases, unilateral carotid artery stenosis in 18 cases, middle cerebral artery stenosis or occlusion in 13 cases. do
