Transcranial magnetic stimulation produces a noninvasive stimulation that excites or inhibits regions of the brain. Theta burst stimulation(TBS), has been considered the most efficient protocol. The impact of TBS on brain perfusion and intrinsic functional connectivity networks of human brains has not been systematically evaluated. Perfusion values were measured with pCASL and resting state fMRI was performed to compare connectivity networks using seed based analysis and matrix based analysis. Perfusion was measured as increased after iTBS. Analysis of seed based data generated from the left dorsolateral prefrontal cortex showed connectivity network changes before and after TBS.
