Simanavi{\vc}iūtė and S. Gudmundsson}, journal={Ultrasound in Obstetrics and Objective: This study aimed to determine the effect of fetal movements on the MCA pulsatility index (PI) and quantify the fall of MCA PI after initiation of fetal movements and/or breathing, and the time taken to recover from a fall below the 5th percentile.

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. Along with the resistive index (RI), it is typically used to assess the resistance in a pulsatile vascular system.

Of the 126 cases, there was decreased MCA PI in 40.5% of fetuses and Feb 7, 2019 Cases with isolated 2VC were retrieved from the database of the ultrasound laboratory at the Division of Prenatal Medicine Department of Jan 11, 2017 Keywords: Doppler ultrasound; indices; normal pregnancy; umbilical artery; uterine Fetal umbilical artery Doppler ultrasound, on the other hand, is often While the PI and RI are measures of resistance to flow in a At the first trimester uterine artery RI and PI were, respectively, 0.83 ± 0.07 and 2.32 ± 0.79 with a notch, blood flow, with a higher risk for developing preeclampsia, IUGR and small-for-gestational-age fetuses(2). Ultrasound O regard to the pulsatility index and Systolic/Diastolic ratio in our population.

The fetal middle cerebral artery (MCA) pulsatility index (PI) is a key parameter used in fetal middle cerebral arterial Doppler assessment. It is calculated by subtracting the end-diastolic velocity (EDV) from the peak systolic velocity (PSV) and then dividing by the time-averaged (mean) velocity (TAV): PI = (PSV - EDV) / TAV

Though controversial, IVC measurement by ultrasound can estimate volume status, fluid responsiveness, and fluid tolerance.

The analysis of the results suggested that Doppler ultrasonography can be used to monitor fetal blood flow changes during the various stages of pregnancy.

Doppler Ultrasound in Fetal Growth Assessment • Uterine artery Doppler • Umbilical artery Doppler • Middle cerebral artery Doppler During fetal hypoxia a pathophysiological adaptation occurs which results in preferential perfusion of vital organs. In the fetal brain this results in decrease in pulsatility index in the MCA as a direct consequence of vasodilation, 28 also referred to as redistribution or the ‘brain-sparing effect’.
