Dating scans, which are often performed around the seventh week of pregnancy, were one of those interventions she said needed questioning.

Rachael McEwing, a radiologist who is on the Maternity Ultrasound Advisory Group, said because unnecessary dating scans were being carried out, some women who really needed scans may not be able to get an appointment.
Ministry of Health statistics show a trend for pregnant women to have more ultrasound scans over the past five years. In , the latest available figures, most had three to five scans. Ms Eddy said another ultrasound women were too often being routinely sent for was a growth scan to check if the baby was bigger than normal. An ultrasound diagnosis of a baby being large for its gestational age is associated with an increased risk of the baby being delivered by caesarean.

Your doctor will use information from obstetric ultrasounds to track pregnancy progress, gestational age and help predict delivery dates.
