How to Calculate Pulsatility Index?
Pulsatility Index calculator uses pulsatility_index = (Peak Systolic Velocity-Minimum Diastolic Velocity)/Average Velocity to calculate the Pulsatility Index, The Pulsatility Index (PI) (also known as the Gosling index) is a calculated flow parameter in ultrasound, derived from the maximum, minimum, and mean Doppler frequency shifts during a defined cardiac cycle. Pulsatility Index is denoted by PI symbol.
How to calculate Pulsatility Index using this online calculator? To use this online calculator for Pulsatility Index, enter Peak Systolic Velocity (v_{systole}), Minimum Diastolic Velocity (v_{diastole}) & Average Velocity (v) and hit the calculate button. Here is how the Pulsatility Index calculation can be explained with given input values -> 0 = (10-10)/75.
