High pulsatility index
WebJan 17, 2024 · Ultrasonography is used in the evaluation of urinary disorders, and the resistivity index (RI) and pulsatility index (PI) have been successfully used to detect early hemodynamic changes in the course of kidney diseases in humans and dogs. The aim of this study was to investigate RI and PI in cats with feline lower urinary tract disease … WebResults: High Pulsatility Index (PI) (>95 th percentile) as compared to low pulsatility Index confers a significant risk (31.58% v/s 2.19%) for Intrauterine Growth Restriction (p<0.05). …

WebUltrasonographic parameters such as the common carotid artery (CCA) pulsatility index (PI) and CCA intima-media thickness (IMT) have been associated with an increased mortality and risk of recurrent stroke, respectively. We hypothesized that these WebBackground: An abnormally high [above mean + 2 standard deviations (SD)] umbilical artery (UA) pulsatility index (PI) indicates impaired fetal outcome, whereas the impact of an "abnormally" low (below mean -2 SD) PI is unknown. Methods: Perinatal outcome was compared between cases with a UA PI less than mean -2 SD (group A: high-risk cases …
WebMay 30, 2024 · Pulsatility index (PI) This is calculated by the following equation: PI = (PSV - EDV) / TAV = (peak systolic velocity - end-diastolic velocity) / time-averaged velocity Abnormal patterns include persistence of a high resistance flow throughout pregnancy persistence of notching throughout pregnancy
