## Abstract A modification to the 3D modified driven equilibrium Fourier transform (MDEFT) imaging technique is proposed that reduces its sensitivity to RF inhomogeneity. This is especially important at high field strengths where RF focusing effects exacerbate __B__~1~ inhomogeneity, causing signif

β¦ Synopsis
T 1 -weighted images of the human brain obtained with the MDEFT sequence at 8 T are presented. These images are characterized by an excellent contrast and good signal to noise ratio. Importantly, results were obtained with adiabatic spin inversion and demonstrate that such pulses can be used even in the ultra high frequency ( \300 MHz) range. It is thus possible to obtain high quality results at this field strength without violating SAR guidelines.

In this work, we present the first human magnetic resonance image (MRI) obtained at ultrahigh field strengths (8 T). We demonstrate that clinical imaging will be possible at 8 T and that reasonable quality head images can be obtained at this field strength. Most importantly, we emphasize that the po

The authors present a transaxial image of the human head acquired at 8 T in a plane above the ventricles, from which they 'demonstrate that clinical imaging will be possible at 8 T and that reasonable quality head images can be obtained'.
