Cephalometry and thoracometry by means of ultrasound represent two useful methods of foetal biometry. Cephalometry, the technique of which is simple and well documented, is irreplaceable as a method of monitoring high risk pregnancies and as a means of detecting anomalies of foetal growth. However, when there is evidence of chronic foetal distress, thoracometry can compensate for the diagnostic shortcomings of cephalometry. In cases of diabetic pregnancy only thoracometry is able to detect foetal oedema. Combination of the two parameters makes possible, when only one measurement is made, a good approximation of the weight of the foetus even in pathological pregnancies.
