Disruption of nutrient delivery through the endplates of
intervertebral discs could be a factor initiating or
accelerating the degeneration processes. Thus, our goal
was to develop a high spatial resolution Dynamic
Contrast Enhanced MRI (DCE-MRI) protocol to study solute
transport mechanisms in the cartilaginous endplates and
subchondral bone of degenerating discs. Results indicate
that the cracks and fissures developing in the
subchondral bone of degenerating discs lead to increased
DCE-MRI enhancement. Furthermore, caudal endplates
showed higher enhancement than cranial endplates and the
difference increased at lower lumbar levels.
