Arterial LE
Calculated Fields
In the Arterial LE worksheet, the following fields are calculated automatically. These calculated values automatically update when any of the source values are changed.
Field | Source Values | Calculation Logic |
|---|---|---|
Arterial Ratio | Arterial PSV values | PSV ÷ PSV of Proximal segment |
Graft Ratio | Graft PSV Values within same graft | PSV ÷ PSV of Proximal segment |
Stent Ratio | Stent PSV Values within same stent | PSV ÷ PSV of Proximal segment |
Atherectomy Ratio | Atherectomy PSV Values within same Atherectomy | PSV ÷ PSV of Proximal segment |
Balloon Angioplasty Ratio | Balloon Angioplasty PSV Values within same Balloon Angioplasty | PSV ÷ PSV of Proximal segment |
The Arterial LE and Abdominal Aorta worksheets in Studycast enable users to quickly document velocities proximal and distal to stenosis with the click of a button.
Adding Pre and Post Stenosis Velocities
The study types with support for this feature each have a + Stenosis button, located in the top left of the measurements and observations section of the worksheet.
1.Click the + Stenosis button.
2.Once clicked, you will be prompted to select the vessel or vessels in which the stenosis occurs. Select the appropriate vessel(s) and click Submit.
3.You will now see proximal and distal fields ( Prox to Sten and Dist to Sten) above and below the vessel(s) which contain the stenosis. Use these fields to document the velocities and distance from stenosis, as well as the ratio, if desired.
Not Visualized Vessels
Note: “Not visualized” should not be used in the same capacity as an “inconclusive” result. Please use the observations dropdown fields to mark vessels “inconclusive”. |
To use this feature, navigate to any of the supported worksheets and find the eye icon, which is located to the right of the vessel label.
This icon toggles between two states, which are shown in the table below.
Icon | State | Description |
inactive | When the icon is inactive, it has no impact whatsoever on your worksheet or report. This is the state you will see by default in the worksheet. | |
active | When the icon is active, it indicates that the vessel was looked for, but was not visualized. It will lock the row of observations for the designated vessel, and will be reflected in the Findings statements, as well as the study report. |
The eye icon will default to an inactive state.
Marking a vessel as “not visualized”:
Click on the inactive eye icon. The icon will now be in an active state. This will clear and lock the entire row of observations (dropdowns) for the vessel.
To see this reflected in your Findings statements, click Generate All Findings. The statements will now reflect that the vessel was not visualized.
In the study report, vessels marked “not visualized” will now appear in the observations and measurements table as N.V. or Not visualized.
To remove a vessel’s status of “not visualized”:
Click on the active eye icon. It will now be in an inactive state, and the row of observations will no longer be locked.
To see this reflected in your Findings statements, click Generate All Findings. The statements will no longer reflect that the vessel was marked “not visualized”.
