Most pregnant women will have an ultrasound scan during their pregnancy. This simple test is quite safe for both mother and baby and causes only minor, if any, discomfort. Ultrasound is a way of taking a look at the baby without using potentially dangerous X-rays. During an ultrasound scan, high-frequency soundwaves are used to create moving images of the developing baby, shown on a screen.
You will still have your dating, 20 week / anomaly and growth scans as usual. you should contact your community midwife before attending the appointment.
Ultrasound is a safe and widely used imaging technique. Ultrasound produces detailed pictures of the body in real-time using high frequency sound waves, which are produced by a special ultrasound probe, called a transducer. The frequency of these sound waves is higher than that detected by the human ear and when they are reflected by a part of the body they are detected by the probe and used to create images that can be displayed on a monitor.
Because they are captured in real time they appear as moving images not as static or still ones, thus enhancing the diagnostic capability of the test. Ultrasound has no known harmful effects and can be used to image a variety of conditions including pregnancy, gallstones and varicose veins. Ultrasound can also be used to measure blood flow through vessels, when it is called a colour flow Doppler or Duplex scan.
Pregnancy ultrasounds may be performed by examination of the abdomen called transabdominal or by using a special probe designed to be inserted into the vagina, called transvaginal. The type of examination you will need will depend on what your referring doctor has requested and the nature of the clinical condition being investigated. Your examination or scan will be performed by either a Radiologist a highly trained specialist doctor or a sonographer a specially trained technologist.
Because the examiner is interpreting moving images on a screen a high degree of concentration is required to obtain accurate information. Therefore, in most circumstances except obstetric scans, family and friends of the patient are not generally permitted to watch the procedure.

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.
