Notes:
Porosity and pore size are critical features for biomaterial scaffolds as they play anessential role in bone formation and bone ingrowth in vivo. Therefore, techniques forscaffolds evaluation are of great importance for their design and processing. Porous titaniumhas been used for grafts and implant coatings as it allows the mechanical interlocking of thepores and bone. In this study, porous titanium samples were manufactured by powdermetallurgy. The porosity quantification was assessed by optical quantitative metallographicanalysis, and non-destructive gamma-ray transmission and X-ray microtomographytechniques, in order to compare their efficacy for porosity evaluation. Pore morphology andsurface topography were characterized via scanning electron microscopy. These techniqueshave demonstrated to be suitable for titanium scaffolds evaluation, and micro-CT was the onethat allowed the three-dimensional porosity assessment
