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 th...
