Medicolegal activity in obstetrical and gynaecological ultrasound.

We surveyed obstetricians who are members of the Australian Association of Obstetrical and Gynaecological Ultrasonologists for details of actions in which they had been asked to give an expert opinion between 1993 and 1998. We uncovered 50 cases, most of which involved missed fetal anomalies. Our findings suggest there is considerable medicolegal activity in obstetrical and gynaecological ultrasound in Australia.
