The Norwegian consensus conference on ultrasound in pregnancy 1986 stated that a beneficial effect of routine ultrasound examinations had not been scientifically proven. Despite this, the panel recommended that, on certain conditions, and in an effort to reduce the number of examinations performed, one examination should be offered to all pregnant women. A survey of the practice of ultrasound examinations has now been carried out. All Norwegian obstetrical institutions were invited to participate. Institutions covering 99.6% of births in Norway registered the number of examinations that had been performed on women delivering during a 7-day period. The main finding is a change in the practice of ultrasound in relation to a similar investigation in 1986: On average, each woman is now examined 2.23 times, compared with 2.46 in the 1986-survey. One or two examinations are now more common than in 1986, when a greater number of women were examined more often. Almost every pregnant woman is now examined with ultrasound, and there are now more institutions offering routine screening examination.
