The potential clinical utility of SPECT (Single Photon Emission Computed Tomography) brain imaging to clarifying certain diagnostic dilemmas faced by clinical psychiatrists is considered generally and is illustrated by several case vignettes. Three case histories consider dementia vs depressive pseudodementia, two the possibility of a cerebral vasculitis in patients with auto-immune conditions, and two whether the patient had a "type" of depression likely to benefit from a course of ECT. Published studies reviewing the utility of SPECT in dementia, depression, depressive "pseudodementia" and cerebral lupus are considered. It is suggested that SPECT is an important investigatory technique providing additional information that may assist some diagnostic decisions, while its utility in assisting other clinical decisions awaits clarification.
单光子发射计算机断层扫描（SPECT）脑成像在澄清临床精神科医生面临的某些诊断困境方面的潜在临床效用进行了总体探讨，并通过几个病例 vignettes 进行了说明。三个病例史涉及痴呆与抑郁性假性痴呆的鉴别，两个病例涉及自身免疫性疾病患者发生脑血管炎的可能性，还有两个病例涉及患者是否患有可能从电休克治疗（ECT）疗程中获益的“类型”抑郁症。对已发表的关于 SPECT 在痴呆、抑郁症、抑郁性“假性痴呆”和脑狼疮中的效用的研究进行了综述。结果表明，SPECT 是一种重要的检查技术，可提供额外信息，有助于一些诊断决策，而其在协助其他临床决策方面的效用尚待明确。
