Summary
The ultrasonic measurement of the fetal crown-rump length (CRL) in early pregnancy was utilized to predict the date of delivery in 220 patients with reliable menstrual histories and in 186 patients with unreliable menstrual dates who began labour spontaneously. Ninety-five per cent and 96·2 per cent respectively were delivered within 12 days of the predicted date. The CRL was found to be better than biparietal diameter measurements (p<0·001) and as good as a reliable menstrual history (p<0·5) in predicting the time of spontaneous onset of labour.
