Early Detection of Tibial Cartilage Degradation and Cancellous Bone Loss in an Ovariectomized Rat Model

Figure 2

Comparisons of ultrasound results measured at medial tibial plateau (MTP) between the OVX and sham groups. (a) Reflection coefficient (RC₁) of the cartilage surface; (b) ultrasound roughness index (URI); (c) cartilage thickness ; and (d) reflection coefficient (RC₂) of the cartilage-bone interface. Statistically significant difference at level exists between OVX group and sham group. Statistically significant difference at level exists between OVX group and sham group.
