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

Table 3

The correlation coefficients between CT value and ultrasound GV and between CT mask volume and ultrasound section pixel in the CS and the CS/nHAC groups. High correlation with low 𝑃 value demonstrates that the property evaluation is analogue between ultrasound and CT.

	CT HU𝑚 and ultrasound GV	CT mask volume and ultrasound cross-section pixel
CS	𝑟=0.967, 𝑃=0.001	𝑟=0.906, 𝑃=0.023
CS/nHAC	𝑟=0.949, 𝑃=0.000	𝑟=0.871, 𝑃=0.001
