Axial
images are obtained with T1-weighted,
and fat-suppressed T2-weighted FSE sequences.
If the fat suppression is inadequate
in the axial plane, these images may
require supplementation with a T2*-weighted
GRE technique, either 2D or 3D. Axial
images must extend from the distal radioulnar
joint through the proximal metacarpals.
