Verkalkung versus Ossifikation
Ossifikationen
in der Falx: Man erkennt in der CT deutlich auch Markraum, der in der MRT (T1 nativ koronar) hyperintens, also fetthaltig zur Darstellung kommt. Bei reinen Verkalkungen ist dies nicht zu sehen.
In discussing mineralization, many radiology textbooks use the term calcification and make no mention of ossification.
- 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.
- calcification
- 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
