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.
