The present chapter reviews the main technical aspects, indications and
results of clinical use of three-dimensional ultrasonographic lung volumes. There are
two methods to measure fetal lung volumes using three-dimensional ultrasonography:
the technique of parallel slices and the rotational technique. Nowadays, the rotational
technique is the method of choice because of reproducibility and less time consuming.
Clinical indications for assessing fetal lung volumes are congenital anomalies or
situations where there is an increased risk for severe pulmonary hypoplasia. Fetal lung
volume is useful tool to diagnose pulmonary hypoplasia, but more important to predict
the severity of this complication. Clinical situations that may benefit from fetal lung
volume assessment are: congenital diaphragmatic hernia, fetal hyperechogenic lung
lesions, omphalocele, premature rupture of the membranes and prolonged
oligohydramnios (fetal renal/urological problems).
