摘　　要：目的:探讨焦虑症患者局部脑血流量(rCBF)特点及脑单光子计算机断层扫描(SPECT)对焦虑症的诊断价值。方法:选择27例焦虑症患者和20例正常对照进行脑SPECT显像,并比较检查结果。结果:焦虑症组在额叶、部分颞叶和丘脑的rCBF明显低于对照组(P<0.05或0.01)。结论:焦虑症对脑血流灌注有重要影响,SPECT脑血流灌注显像在焦虑症的诊断与鉴别诊断中有重要价值。Objective： To study the characteristics of the regional cerebral blood flow and the diagnostic value of brain SPECT in patients with anxiety disorders. Methods： 27 patients with anxiety disorder and 20 normal controls were performed brain SPECT imaging in which examination results were compared. Results： Lower radioactivity rate in bilateral frontal lobes, anterior temporal lobes and cerebral ganglion were demonstrated in the anxiety patients （P〈0.05）. Conclusion：The anxiety disorders have obvious effect on cerebral blood flow, and radionuclide imaging have important value in the diagnosis and differential diagnosis of anxiety disorders.
