Brain imaging (MRI’s, CT’s, etc.) is not necessary to determine the appropriate area of TMS treatment for depression. The area of treatment known as the Dorsal Lateral Pre-Frontal Cortex (DLPFC) can be properly located and confirmed without the use of brain imaging scans. There is no research supporting the notion that treating an area of your brain other than the DLPFC or using scans to locate other areas delivers better outcomes than the FDA method.
