WebMiddle cerebral artery peak systolic velocity, measured by Doppler ultrasonography, is an accurate test for detecting fetal anemia.101,102 This technique is noninvasive and therefore presents no risk of miscarriage or preterm labor, and thus is a preferable method of screening for fetal anemia when compared to invasive alternatives.

With threshold values of RIR greater than 5, PSV greater than 150 cm/s in the renal artery, renal-aortic ratio greater than 2, … Webdiagnosed by no ﬂow in the renal artery. We have included two analyses. Our main analysis includes occlusion in the “greater than” groups so that it is those that have no ﬂow or a PSV equal to or greater than a speciﬁc velocity (eg, no ﬂow or a PSV 285 cm/s for 60% RAS). Another analysis is included where the occlu-sions were excluded. finding the face value of a bond
