The Diameter Symmetry of a Stenosis is a parameter determining the symmetry in arterial plaque distribution.

The Symmetry Index is defined by:
**a**
/
**b**
where
**a**
is smaller or equal to than
**b**
.
**a**
and
**b**
are measured in the reconstructed artery at the position of the minimal luminal diameter.

Possible values of symmetry range from 0 to 1, where 0 indicates complete asymmetry and 1 indicates complete symmetry.
