Why the study?
Does factoring real-time pulsatility index values into blood volume flow calculations improve the accuracy of flow measurements in lower extremity arteries?
Does factoring real-time pulsatility index values into blood volume flow calculations improve the accuracy of flow measurements in lower extremity arteries?
Adjusting Doppler flow measurements by pulsatility index yields more accurate and stable clinical evaluations of lower extremity arteries.
May refine Doppler volume-flow estimates in lower-extremity arteries but should not yet change practice; leaves open prospective confirmation.
When real-time PI values are factored into blood volume flow calculations in the evaluation of lower extremity arteries, discrepancies in flow measurements can be resolved, resulting in more accurate and stable measurements of clinical and diagnostic significance.
