The CT shows a complex plaque with calcific and non-calcific elements causing significant narrowing. In such situations, accurate measurements are not easy, but there is an obvious high-grade stenosis, which is greater than 70% (which is all that matters in clinical practice).

In this case, to better assess the lesion, a vessel view technique was applied, in which the vessel is straightened out and rotated through its own axis, so that the lumen can be assessed throughout 360 degrees. This made a big difference in assessing the lumen.
