Electroconvulsive Therapy Decreases Dopamine D<sub>2</sub> Receptor Binding in the Anterior Cingulate in Patients With Depression: A Controlled Study Using Positron Emission Tomography With Radioligand [<sup>11</sup>C]FLB 457

Results: There were no significant differences in D2 receptor binding between patients with MDD and controls. All 7 patients showed clinical improvements in response to ECT treatment (P<.001). Significant changes in D2 receptor binding, a mean of 25.2% reduction, were found in the right rostral anterior cingulate (AC) following ECT (P<.001).
