Potential impact of 32 channel receiver coil technology on functional magnetic resonance imaging

Purpose: Using finger tapping as the standard motor task for functional magnetic resonance imaging (fMRI), we aimed to test the potential of a 32 channel coil for performing fMRI compared to a standard 8 channel coil. Methods: Brain activations were investigated in 14 healthy right-handed subjects performing finger tapping with the right index finger during two experimental sessions, one with the 8 channel coil and one with the 32 channel coil. The order of both sessions was pseudorandomized. The experiment was carried out based on a conventional block design and functional imaging data were analyzed using SPM5.…
