title: Problems in ultrasonic monitoring of multiple pregnancies.
abstract: Ultrasound would seem to be an ideal method of ensuring the early diagnosis of multiple pregnancy and also affords an opportunity to measure individual fetal growth thereafter. In a programme to study multiple pregnancies the majority were diagnosed early to allow adequate regular monitoring by ultrasound. Unexpected problems were encountered however and the failure rate to obtain satisfactory fetal biparietal measurements was almost three times that in singleton pregnancies.
