CID 3493 IVUS Relative Stenosis Severities​

This context group is a set of stenosis severity classifications for multiple lesions within a segment. There will always be a worst​ stenosis (T-1), the stenosis with the smallest lumen size.​

There can be multiple secondary stenoses (T-2, T-3, etc.), which are lesions meeting the definition of a stenosis, but with lumen sizes​ larger than the worst stenosis.
