title: Early detection of intrauterine pregnancy with ultrasound.
abstract: Vaginal scanning is a relatively new technique for scanning early pregnancy. In a consecutive series of 27 patients on an in vitro fertilization program (and therefore certain dates of ovulation) we have demonstrated that pregnancies may be seen within the uterus even before 5 weeks amenorrhoea and have documented their size. Ultrasound examination at this early stage may be of clinical value, particularly in patients suspected of having an ectopic pregnancy.
