ossification vs calcification
In discussing mineralization, many radiology textbooks use the term calcification and make no mention of ossification.
- is a process of laying down new bone material; it is synonymous with bone tissue formation.
- Therefore, in many cases, one can differentiate between cortical and cancellous bone (in the latter one may identify fatty marrow).
- Bone may form in any region where there are fibroblasts, an excess of calcium and an adequate blood supply.
- is the process in which calcium salts build up in soft tissue, causing it to harden.
- calcifications may be classified on whether there is mineral balance or not, and the location of the calcification.
- pathological calcification is observed in any mesenchymatous tissue of low metabolism when the vascularity is further reduced by the fibrosis of trauma or infection.
- calcifications usually have a more amorphous appearance than the more structured ossifications
