Unless there are concerns about the pregnancy it is better to wait to have this scan after 7 weeks as the images are clearer for you to see and better for us to measure. If you come before 7 weeks the baby will be less than 1cm in size and so the scan sometimes has to be performed transvaginally placing the probe inside the vagina to enable us to see the baby well enough to measure and to see the heartbeat. We ask that you come with a full bladder for this scan as it usually allows us to get the best possible picture of the baby. If you decide to go ahead with this optional screening test you will be offered a scan between 12 weeks and 13 weeks 6 days ideally 12 weeks. This is the only time that this scan can be performed. We send these measurements to LabPlus in Auckland where a blood sample from you is also sent. LabPlus then calculate the risk or chance that your pregnancy is affected with Down Syndrome. Because this calculation is not carried out on site we are not able to give you the results straight away on the day. LabPlus will contact your midwife with the results and she will discuss the results with you. This is a detailed ultrasound scan, usually carried out when you are 20 weeks pregnant.

Dating scans, which are often performed around the seventh week of pregnancy, were one of those interventions she said needed questioning. As soon as a pregnancy test returns a positive result, most women are able to work out when their baby is due using one of the numerous due date calculators on the internet or with the help of their GP. Dating can be done at the nuchal translucency scan which can detect chromosomal abnormalities at about the twelfth week of pregnancy.
The other is an anatomy scan, where a lot of important developmental problems can be picked up, around 20 weeks. While a pregnant woman might be eager to see that flickering heartbeat and reassure herself all was well with her bub-to-be, Ms Eddy said they should instead be guided by the usual early pregnancy symptoms such as nausea, fatigue and having tender breasts.
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.

Pregnancy these days can be a minefield of medical examination and testing, from the time you first do the home pregnancy test until the moment baby takes his or her first breath, and even after then. Most women accept the barrage of testing without question, feeling that the more information they can have, the better, whereas others opt out of some or all of them entirely.
Many people will also use this one to find out the sex of the baby. Facebook and other social media sites are often awash with images expectant parents put up to share their growing baby with the world. So with all this in mind, we must ask the question: how safe is ultrasound really? And how necessary? The vast majority of women will undergo at least one scan during pregnancy, generally aimed at ensuring the developing foetus is growing normally and is free from the myriad congenital abnormalities that can be viewed by sonography.
Generally the view is that the sooner you know about something, the easier it will be to treat and the better the outcome. However, there is also evidence that for all the good they can potentially do, ultrasounds could possibly be harmful to the growing fetus, being linked in recent years to various neurological problems, intra-uterine growth restriction, and other health problems, and the scans may not even make any significant difference to the outcomes for those infants in whom a congenital abnormality is detected.
There are a number of issues with ultrasound that many women may not be aware of, each of which could be the subject of an entire story — please consider this a mere overview! Firstly, the level of radiation exposure and dosage of ultrasound used varies across equipment, meaning broad differences in potential levels a fetus may be exposed to.
Many people are unaware that this is a form of pulsed ultrasound with much higher output than other forms, and that there are non-radiation alternatives available on request such as wooden pinard horns fetoscopes.
