T2-weighted images and T2 maps of intervertebral disks are investigated for use as biomarkers in a rabbit model of disk damage and degeneration. T2 proves to be an effective indicator of damage/degeneration of intervertebral disks. Ongoing work includes the use of T2 to evaluate recovery/regeneration in treatment with various agents, including rabbit articular chondrocytes and human umbilical stem cells.
