      abstract     = {Trimodal simultaneous acquisition of positron emission
                      tomography (PET), magnetic resonance imaging (MRI), and
                      electroencephalography (EEG) has become feasible due to the
                      development of hybrid PET-MR scanners. To capture the
                      temporal dynamics of neuronal activation on a
                      millisecond-by-millisecond basis, an EEG system is appended
                      to the quantitative high resolution PET-MR imaging modality
                      already established in our institute. One of the major
                      difficulties associated with the development of simultaneous
                      trimodal acquisition is that the components traditionally
                      used in each modality can cause interferences in its
                      counterpart. The mutual interferences of MRI components and
                      PET components on PET and MR images, and the influence of
                      EEG electrodes on functional MRI images have been studied
                      and reported on. Building on this, this study aims to
                      investigate the influence of the EEG cap on the quality and
                      quantification of PET images acquired during simultaneous
                      PET-MR measurements. A preliminary transmission scan study
                      on the ECAT HR+ scanner, using an Iida phantom, showed
                      visible attenuation effect due to the EEG cap. The
                      BrainPET-MR emission images of the Iida phantom with
                      [18F]Fluordeoxyglucose, as well as of human subjects with
                      the EEG cap, did not show significant effects of the EEG
                      cap, even though the applied attenuation correction did not
                      take into account the attenuation of the EEG cap itself.},
