Abstract:Objective: To study the characteristics of regional cerebral blood flow(rCBF) and the diagnostic value of brain SPECT in patients with depressive disorder and anxiety disorders. Methods: SPECT were performed in 21 depressive patients, 17 anxiety patients to compare the difference in cerebral perfusion. Region of interest(ROI) in cross-sectional images of the brain lobes were drawn, to semi-quantitatively analyse the rCBF changes of depression and anxiety disorders in patients. The t test was used to analyze the quantitative data. Results: Lower radioactivity rate in bilateral prefrontal lobes, temporal lobes, occipital lobes, bilateral parietal lobes, cingulated gyrus, caudate nucleus were demonstrated in the depressive patients(P<0.05 or 0.01). Lower radioactivity rate in bilateral frontal lobes, anterior temporal lobes and cerebral ganglion were demonstrated in the anxiety patients(P<0.05 or 0.01). Conclusion: The depressive disorder and anxiety disorders have obvious effect on cerebral blood flow. Radionuclide imaging have important value in the diagnosis and differential diagnosis of depressive disorder and anxiety disorders.
