We have achieved highly accelerated 3D dynamic contrast
enhanced (DCE) wrist MRI in Rheumatoid Arthritis (RA)
patients with improved image spatial (0.3x0.3x1.5mm) and
temporal resolution (5s), with an acceleration factor
R=20. Evaluation of neovascularization and perfusion in
RA joints demonstrated that the improved images could
provide accurate assessment of the RA progression.
