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.
