A pilot study examined 23 patients who underwent simultaneous ultrasound and amniocentesis to determine whether the ratio of densitometrically determined tissue densities of fetal lung and liver correlate with the US, the OD 650, or phosphatidylglycerol levels. The incidence of a lung/liver ratio > 1 of 65% was similar to that of maturity levels of the standard tests. However, there was no statistically significant correlation between an UL > 1 and/or any maturity parameter tested, nor was there any correlation with the absence of pulmonary maturity. We conclude that this test cannot be reliably used to predict US, OD 650 reading, or PG levels.
