In Vivo Evaluation of an Injectable Premixed Radiopaque Calcium Phosphate Cement

Figure 5

Diagram showing the osteoblast activity in the operated vertebra compared to the adjacent vertebra. The lines represent the mean value and the dots the individual animals value. The 12-week nano-SPECT/CT followup showed the highest osteoblast activity in the pCPC group during the first 5 weeks. Although the differences between the three groups level off after the 5th week, pixel intensity stays higher in all three groups compared to the neighbouring healthy vertebra.
