Abstract: Magnetic Resonance Imaging has become in the past 20 years the imaging modality of choice in the study of the brain and the diagnostics of its pathologies. As the technique developed, it became more and more versatile, due to its richness of parameters and complexity of functioning. With time, multimodality approaches started being studied, not only within MRI itself but combining MRI with other techniques. One of the most promising combinations has been the simultaneous acquisition of EEG and fMRI, where an EEG signal is acquired within the MRI machine while a functional MRI exam is taking place. Because if its high temporal resolution and capability to easily detect ictal and interictal brain activity in epileptic patients, EEG can be used to time trigger the occurrence of these events during the fMRI acquisition, which in turn can provide a very good spatial localization of the activity. Although there some problems still to be ironed out and some conceptual questions still being solved, the technique has been very successfully used in several epileptic patients with very interesting and clinically relevant results. The presentation will go through the main principles of the simultaneous acquisition technique, describe its practical implementation, discuss some of its problems, and show some of the clinical results obtained so far.
