Abstract
An optimization scheme was developed for gradient echo imaging using a halfβbirdcage RF coil at 7 T to obtain maximal contrast between gray and white matter in the spinal cord of rodents. This optimization was combined with microimaging techniques to obtain in vivo pixel sizes of 78 Γ 78 Γ 700 ΞΌm. These techniques can be implemented in an in vivo study to investigate the myelin structure within the white matter of the rodent spinal cord.

In vivo diffusion tensor imaging (DTI) of rat cervical and thoracic spinal cord was performed using a three-element phased array coil at 7 T. The magnetic field was shimmed over the spinal cord in real time using an in-house developed automatic algorithm. Echo planar imaging (EPI)-based diffusion-we
