Osteogenesis Capability and Degradation Property Evaluation of Injectable Biomaterials: Comparison of Computed Tomography and Ultrasound

Table 2

CT value (HU_𝑚) and mask volume (calculated from voxel) of the implants. HU_𝑚 tendency, on the uptrend, is similar as ultrasound GV, while the mask volume is in a downtrend with time. The data are expressed as mean ± SD.
