DESCRIPTION:Caroline Le Ster\, CEA Neurospin\, Paris\, France\nHosted by 
 Frédéric 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 CES
 T by Caroline Le Ster from the CEA Neurospin\, Paris who will be sharing o
 n “Leveraging the potential of UHF scanners for fMRI studies”.\nAbstra
 ct\nThere is a growing availability of 7T scanners\, with approximately 10
 0 systems currently installed worldwide. These ultra-high-filed (UHF) scan
 ners are particularly relevant for neuroimaging\, where anatomical and fun
 ctional 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. Thes
 e systems indeed face several challenges arising from MR physics and biolo
 gical effects that must be addressed within engineering constraints. Lever
 age the potential of UHF scanners\, for instance through field monitoring\
 , is therefore important to make the most of these scanners and benefit fr
 om the intrinsic SNR gain.\nfMRI particularly benefits from the increase i
 n magnetic field strength\, enabling studies to be performed at higher res
 olution than at lower fields. In order to maintain reasonable acquisition 
 times despite larger imaging matrices\, several acceleration strategies ha
 ve been developed\, e.g. multi-slice EPI (SMS-EPI)\, three-dimensional EPI
  (3D-EPI) and non-Cartesian sampling schemes. In addition\, functional con
 trasts also benefit from the field increase\, including improved spatial l
 ocalization of the BOLD contrast and the possibility to exploit VASO contr
 ast.
