In this study, the cartilage volume, thickness and T2 value of mild to moderate knee osteoarthritis were quantitatively measured by using automatic cartilage segmentation software.
Figure 1. Comparison of the differences of the cartilage volume (a), thickness (b) and T2 relaxation times (c) between mild and moderate OA group.
* Statistically significant (P < 0.05).

example of automated cartilage segmentation: (a) Sagittal view of a knee with
the automated cartilage segmentation. According to the anatomical position, the
cartilage of knee joint was automatically divided into several small regions;
(b and c) automated segmentation view, and the software automatically extracted
the cartilage and display 3D images.
