PULSATILITY INDEX (PI) (2) End-diastolic flow velocities first appear at 13-14 gestational weeks (coinciding with the appearance of end-diastolic velocities in the umbilical artery and descending aorta). End-diastolic velocity is present in 50% of fetuses at 15 weeks and in all cases after 17 weeks.

Figure 10: Pulsatility index (left) and mean blood velocity (right) in the fetal middle cerebral artery with gestation (mean, 95th and 5th centiles). In healthy fetuses, impedance to flow in the fetal aorta does not change with gestation during the second and early third trimesters of pregnancy, but it subsequently decreases ( Figure 7 ) 15,20–22 .

As fetal Doppler examination in the late second and third trimesters is rarely performed routinely where no indication exists, these charts are of potential utility in the setting where referrals to a fetal assessment unit are made for fetal growth, amniotic fluid, biophysical profiling and fetal Dopplers.Figure 1 -Figure 2 -12Umbilical artery pulsatility index: mean, 5th and 95th percentiles Umbilical artery pulsatility index and fetal abdominal circumference in isolated gastroschisis. Download. Whether the results of ultrasound examinations undertaken for monitoring according to several published protocols 3,16 should be compared to population 'normal' ranges for growth and Doppler indices is a moot point, Detailed ultrasound examination. Ultrasound scans every 1 week to monitor growth, amniotic fluid volume and pulsatility index in the umbilical artery, middle cerebral artery and ductus venosus of both fetuses.

J G Martins Department of Obstetrics and Gynecology, Eastern Virginia Medical School, Maternal Fetal Medicine, USA. 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 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.

Conversely, adverse perinatal outcomes are uncommon in growth-restricted fetuses with normal results at umbilical artery Doppler velocimetry. PULSATILITY INDEX (PI) (2) End-diastolic flow velocities first appear at 13-14 gestational weeks (coinciding with the appearance of end-diastolic velocities in the umbilical artery and descending aorta). End-diastolic velocity is present in 50% of fetuses at 15 weeks and in all cases after 17 weeks. The CPR is the ratio of the umbilical artery pulsatility index over the middle cerebral artery pulsatility index. A low CPR reflects fetal redistribution and is thought to be indicative of placental insufficiency independent of actual fetal size, and a marker of adverse outcomes.
