Abstract

Iliac length measurement is increased in fetuses with Down syndrome. An observed-to-expected iliac length measurement of > or = 1.21 has a positive predictive value of 1/38 in a low-risk population with a false-positive rate of 2%. This preliminary study suggests that iliac length measurement may be useful as an ancillary screening variable in antenatal screening for Down syndrome.
