Webtation in dogs.29 A few years later, the same group reported that the MCA mean blood velocity was not an optimal parameter to assess fetal anemia.30 The reference range for the MCA-PSV was reported in 1995 (Fig. 1).31 In the same study, it was reported that all the anemic fetuses had an MCA-PSV greater than the mean of the range of normal values. WebThe most commonly assessed Doppler flow studies of the fetus are the umbilical artery and middle cerebral artery (MCA). Doppler flow studies of the MCA are used in the assessment of the fetus at risk for anemia and growth-restricted fetus.

It is a useful predictor of fetal distress and intrauterine growth restriction (IUGR). Interpretation Normal WebTo develop gestational age-based reference ranges for the pulsatility index in the umbilical artery (UA-PI) and fetal middle cerebral artery (MCA-PI) and the cerebroplacental ratio (MCA-PI/UA-PI), and to examine the maternal characteristics and medical history that affect these measurements.
