Monitoring of glottal behavior during dynamic MRI
studies is desired for better understanding of the
physiologic process of singing. To this aim an EGG
device was modified to enable simultaneous EGG
measurements during MR image acquisitions. After
successfully applying the safety measurements according
to the standards, simultaneous EGG recording with either
dynamic 3D FLASH or 2D trueFISP image acquisitions in a
34y-old singer was performed during different phonatory
tasks.
