Double inversion recovery (DIR) methods are used to
generate gray matter (GM) specific images by
simultaneously nulling the signals from CSF and white
matter (WM). By using a new, efficient MP-nRAGE method,
it is possible to generate an entire set of whole-brain,
high-resolution, 3D inversion recovery contrast images
with tissues nulled in different frames. By taking the
ratio of the minimum intensity projection to the maximum
intensity projection images of the CSF and WM null
frames, it is possible to generate high quality GM maps
with minimal coil sensitivity effects.
