The head and vertebral column from two human cadavers were injected wi
th a solution of gelatin and gadolinium (Dotarem(R)) and imaged using
magnetic resonance imaging (MRI). Comparisons between gross anatomic s
lices and corresponding images of the lumbar vertebral column confirme
d the usefulness of a paramagnetic agent for visualising the epidural
venous plexus. This technique provides accurate images of the posterio
r longitudinal ligament.
