Snapshot gradient-recalled echo-planar images of rat brains at long echo time at 9.4 T

Rolf Gruetter, Hongxia Lei, Nathalie Just

With improved B-0 homogeneity along with satisfactory gradient performance at high magnetic fields, snapshot gradient-recalled echo-planar imaging (GRE-EPI) would perform at long echo times (TEs) oil the order of T-2*, which intrinsically allows obtaining ...

Fast Bias Field Correction for 9.4 Tesla Magnetic Resonance Imaging

Jean-Philippe Thiran, Rolf Gruetter, Meritxell Bach Cuadra, Nicolas Kunz, Nathalie Just, Xavier Pena Pina

In this paper the problem of intensity inhomogeneity at high magnetic field on magnetic resonance images is addressed. Specifically, rat brain images at 9.4T acquired with a surface coil are bias corrected. We propose a low- pass frequency model that takes ...
