| component | Blood flow velocity.max.stenosis.internal carotid artery/Blood flow velocity.max.unobstructed.common carotid artery | |
| property | VelRto = Velocity Ratio | |
| time | Pt = Point in time: To identify measures at a point in time. This is a synonym for “spot” or “random” as applied to urine measurements. | |
