It was not until 1979 that Margi Mantoni and Jan Fog Pederson in Copenhagen first described the visualization of the yolk sac, using the static B-scan.Also read a brief discussion on the historical aspects of the fetal trunk circumference measurements.Both had appeared as landmark papers in the Lancet.They were the first cases of these conditions in which a correct diagnosis by ultrasound had effectively led to a termination of pregnancy.

The measurements were done 'blindly' without actually seeing the structures under study.

In 1971, with improvements in the caliper system, Campbell and Newman published normograms for the biparietal diameter from the 13th weeks of gestation and has made cephalometry a standard tool for the assessment of fetal growth and maturity.

Many early paper in cephalometry followed in the late 1960s such as those from Boog in France, Khentov in the USSR, Zacutti and Brugnoli in Italy, Kratochwil in Austria and Pystynen and Ylostalo in Finland.

Ultrasonic diagnosis of molar pregnancies was described as early as 1963 by the same group.

Stuart Campbell's landmark publication in 1968 "An improved method of fetal cephalometry by ultrasound" described the use of both the A- and B-mode scan to measure the fetal biparietal diameter.
