How are coronary artery stenoses reported

How are coronary artery stenoses reported?

Coronary artery plaques are described by:

  • • The vessel and the vessel segment.
  • • Plaque composition (i.e., calcified, mixed, or noncalcified).
  • • Plaque length.
  • • Degree of stenosis.

Degree of stenosis is best characterized by percentage values (e.g., “50%” stenosis). A percentage is more specific than qualitative descriptors such as “moderate,” although the precision with which stenoses can be measured will depend on study quality.
