单纯性眩晕患者可由多种原因造成,其中多因美尼尔希综合征和脑动脉粥样硬化锥基底动脉供血不足(VBI)引起,为了解单纯性眩晕者脑局部血流灌注变化情况,特对18例颅脑CT或MRI无异常的眩晕患者进行SPECT脑局部血流灌注显像和局部脑血流(rCBF)测定。1 对象与方法1.1 研究对象 ①对照组:正常人8例,其中男5例,女3例,平均年龄47.5岁,均无心脑血管病史及体征;②患者组:受检者18例,男13例,女5例,平均年龄51.6岁,均是我院急诊患者, Patients with simple vertigo may be caused by a variety of reasons, most of them due to Minneak syndrome and cerebral atherosclerotic basilar artery insufficiency (VBI) caused by, in order to understand changes in cerebral blood flow in patients with simple vertigo, especially Eighteen patients with vertigo without brain CT or MRI underwent SPECT perfusion imaging and local cerebral blood flow (rCBF). 1 Subjects and Methods 1.1 The study group ① control group: 8 cases of normal, including 5 males and 3 females, mean age 47.5 years, no history of cardiovascular disease and physical signs; ② patients: subjects were 18 cases, male 13 cases, 5 females, average age 51.6 years old, are emergency patients in our hospital,
