Synopsis

Keywords: High-Field MRI, High-Field MRI

Motivation: Ultra-high magnetic field MRI offers new opportunities due to its higher SNR and CNR.

Goal(s): After receiving the authorization for scanning 20 adult healthy volunteers on the whole-body Iseult MRI scanner, we performed a preliminary MRI investigation to acquire the first brain images at 11.7T.

Approach: Using a homemade multi-transmit multi-receive head coil and parallel transmission, 3D anatomical images were acquired with multiple sequences and tissue contrasts at high resolution.

Results: In this study, high quality whole brain images acquired at 11.7T on the Iseult MRI scanner are presented for the first time to the MR community.

Impact: Showing for the first time in vivo brain images acquired at 11.7T on the whole-body Iseult MRI scanner, this study reveals first potential and challenges of such systems to the ultra-high field MR community.
