3D rendering of cartilage was applied to 3D dGEMRIC images of the knee, and used to analyze data from five female marathon runners. Significant areas of the central medial condyle showed change in the dGEMRIC Index one day after running. After 1 week the affected area was reduced and six week after running the cartilage tissue returned to its pre-marathon stage. The 3D rendering techniques provide an analytical tool that can be exploited to measure changes in dGEMRIC over the full area of the joint cartilage, which may supplement the currently utilized 2D approaches to evaluate dGEMRIC changes.
