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 |
Add Stenosis
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.
To document pre and post stenosis velocities:
- Click the + Stenosis button.
- 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.
- 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.
