An Obstetric Ultrasound is a diagnostic imaging procedure that uses sound waves to produce images of the internal structures of your body and your baby’s body.
Reasons that your doctor may request an Obstetric Ultrasound can include to:
- Establish a delivery date for your baby
- Assess the structural development of the baby
- Determine the number of babies
A routine obstetric ultrasound is performed between 19 and 20 weeks of pregnancy. At this time your baby is big enough to allow examination of individual organs. This is essentially your baby’s first check up and a great deal of information can be learnt about your baby.
- A member of staff will explain the examination and answer any questions that you might have.
- You may be required to remove some clothing and wear a gown.
- You will lie on the examination bed and a small amount of ultrasound gel is spread over the area to be examined.
- The sonographer will move the ultrasound probe over your abdomen and save the relevant images. Several measurements will be taken and the Radiologist may be asked to come and look at the images.
- After the examination the gel is wiped off and if possible you will be able to take the pictures with you.
- The test can take up to an hour and a half.
