Parametrics and Non-Parametrics
Parametrics
Using digital microscopy and powerful image analysis software,
stented arterial sections can be evaluated parametrically to
determine the level of stenosis and neointimal thickening.
Qualified pathology staff also provide a quantitative score of
the level of damage done to the test artery by evaluating the
following:
- fibrosis
- RBC count
- multi-nucleated giant cells (MNGC)
- macrophages.

Non-Parametrics
Using similar techniques, a pathologist can qualitatively
measure inflammation, RBC distribution, etc. by assigning a score
to each category.
