Abstract
Sixty patients with less than six weeks amenorrhoea were examined by ultrasonic "B" scanning for the detection of pregnancy. The results were compared with those obtained by histological examination of the aspirate after the patient had undergone menstrual regulation by vacuum aspiration of the uterine contents. The overall accuracy was 79 per cent with 15 per cent false positives. The accuracy after 39 days amenorrhoea was 95 per cent. The technique was compared with an immunological pregnancy test.Keywords
