PURPOSE To minimize artifacts in echo-planar imaging (EPI) of human brain function introduced by simultaneous transcranial magnetic stimulation (TMS). MATERIALS AND METHODS Distortions due to TMS pulses (0.25 msec, 2.0 T) were studied at 2.0 T before and during EPI. RESULTS Best results were obtained if both the EPI section orientation and the frequency-encoding gradient were parallel to the plane of the TMS coil. Under these conditions, a TMS pulse caused image distortions when preceding… CONTINUE READING
