Abstract

Abstract : Background: Transcranial sonography (TCS) is an available and noninvasive neuroimaging method that has been found to reduce the echogenicity of the brainstem raphe (BR) in patients with depression. Applying the criteria of the Diagnostic and Statistical Manual of Mental Disorders‐IV (DSM‐IV), we performed a meta‐analysis of the diagnostic accuracy of TCS. Methods: A systematic search was conducted in PubMed, EMBASE, The Cochrane Library, and Web of Science. The databases were searched from inception to December 2021. The quality of the included literature was assessed using the QUADAS‐2. Heterogeneity analysis was performed. A summary receiver operating characteristic (SROC) curve was generated to evaluate the diagnostic accuracy of TCS. Results: We included 12 studies with 809 patients. The pooled sensitivity was 0.66 (95% confidence interval [CI]: 0.61–0.71), and the specificity was 0.84 (95% CI: 0.80–0.87). The combined positive likelihood ratio (LR) was 3.84 (95% CI: 2.68–5.51), the negative LR was 0.41 (95% CI: 0.29–0.57), and the diagnostic odds ratio (DOR) was 11.45 (95% CI: 5.57–23.02). The area under the curve (AUC) of the plotted SROC curve was 0.86 (95% CI: 0.83–0.89). The meta‐regression and subgroup analyses found no source of heterogeneity. Conclusion: TCS has high potential and efficacy in diagnosing depression and may be a reasonable test to perform clinically for the assessment of depression.
