SUMMARY:7T MRI Seminar: Leveraging the potential of UHF scanners for fMRI studies
DESCRIPTION:Hosted by Frédéric Grouiller ( https://cibm.ch/community/frederic-grouiller/ ), CIBM MRI HUG-UNIGE Section head, we are pleased  to invite you to attend the CIBM 7T MRI Seminar on April 21st at 10:00 CEST by Caroline Le Ster from the CEA Neurospin, Paris who will be sharing on “Leveraging the potential of UHF scanners for fMRI studies”.\nDate and time: Tuesday, April 21st, 2026 – 10:00 CEST\nLocation:  CIBM seminar room, EPFL, Lausanne & online\nAbstract\nThere is a growing availability of 7T scanners, with approximately 100 systems currently installed worldwide. These ultra-high-filed (UHF) scanners are particularly relevant for neuroimaging, where anatomical and functional images can be acquired with higher spatial and temporal resolution than on conventional scanners. However, UHF scanners remain difficult to operate, and understanding their specific limitations is essential. These systems indeed face several challenges arising from MR physics and biological effects that must be addressed within engineering constraints. Leverage the potential of UHF scanners, for instance through field monitoring, is therefore important to make the most of these scanners and benefit from the intrinsic SNR gain.fMRI particularly benefits from the increase in magnetic field strength, enabling studies to be performed at higher resolution than at lower fields. In order to maintain reasonable acquisition times despite larger imaging matrices, several acceleration strategies have been developed, e.g. multi-slice EPI (SMS-EPI), three-dimensional EPI (3D-EPI) and non-Cartesian sampling schemes. In addition, functional contrasts also benefit from the field increase, including improved spatial localization of the BOLD contrast and the possibility to exploit VASO contrast.\n																														\nCaroline Le Ster\nCEA Neurospin, Paris, France\nAbout the speaker \nCaroline studied bioscience engineering before doing her PhD at Siemens Healthcare, dedicated to bone marrow qMRI. After that, she joined NeuroSpin (CEA, France) in 2017 and has been working since then on UHF methodological developments for neuroimaging.\nSeminar Chair\n																														\nFrédéric Grouiller\nCIBM MRI HUG-UNIGE Section head\nClick here to know more about Frédéric ( https://cibm.ch/community/frederic-grouiller/ )\nJOIN US ON SITE!\nYou are welcome to join us on site at the CIBM seminar room, EPFL, Lausanne. The event is for free and registration is not required.\nOR REMOTELY\nTo join us remotely please,  register at the following Zoom link:https://epfl.zoom.us/j/65404945981\nZoom Code: 654 0494 5981\nWe look forward to seeing you there!\n
