目的 评价乙撑双半胱氨酸二乙酯 (99m Tc- ECD) SPECT脑血流灌注显像对眩晕患者的诊断价值。方法 对 19例眩晕患者和 2 0例正常对照者进行 SPECT脑血流灌注显像。结果 突发性耳聋组和诊断未明确组的患者全部出现局部脑血流量下降 ,且多数分布在颞叶 ;梅尼埃病患者组则较少出现局部脑血流量下降 (40 % ,2 /5 ) ;正常对照组未发现局部脑血流量下降。结论 99m Tc- ECD SPECT脑血流灌注显像有助于眩晕患者的病因学研究 ,以及在临床治疗上有一定的指导意义。
Objective To evaluate the diagnostic value of 99m Tc-ECD SPECT cerebral perfusion imaging in patients with dizziness. Methods Nineteen patients with vertigo and 20 normal controls were enrolled in this study. Results All of the patients with sudden deafness and those without definite diagnosis had decreased local cerebral blood flow, most of them located in the temporal lobe. The incidence of regional cerebral blood flow decreased less in the Meniere disease group (40%, 2/5 ); No decrease of local cerebral blood flow was found in normal control group. Conclusion 99m Tc-ECD SPECT cerebral perfusion imaging is helpful to the etiological study of patients with vertigo and has certain guiding significance in clinical treatment.
