Three novel fMRI pulse sequences are evaluated together with simultaneous EEG acquisition, with the aim to reduce the induced EEG Gradient Artifacts (GA), increase the spatio-temporal resolution of fMRI and reduce the acoustic noise during scanning: sinusoidal GE- EPI, multiband blipped-CAIPI and single shot T2-prep RUFIS.

Remarkable results were found for the T2-prep RUFIS sequence, with a significantly reduced gradient artifact amplitude, high temporal resolution and low acoustic noise level, providing eminent advantages to this multimodal technique.
