Abstract

Mental illness affects a substantial proportion of adults in the United States, yet psychiatric diagnosis remains subject to diagnostic variability. Single-photon emission computed tomography (SPECT) is a neuroimaging technique that measures cerebral blood flow and has been proposed as an adjunctive tool for psychiatric evaluation. Existing literature reports group-level perfusion patterns associated with certain psychiatric conditions, suggesting potential utility in diagnosing complex or treatment-resistant cases. However, critics of SPECT emphasize the absence of randomized controlled data demonstrating improved patient outcomes. To address this gap, a prospective randomized controlled trial comparing standard psychiatric care with SPECT-guided evaluation is proposed. The proposed trial tests the hypothesis that SPECT-guided psychiatric evaluation results in improved clinical outcomes compared to traditional evaluations.
