The arms, legs, hands and feet are checked to see if they are present. The kidneys and bladder will be checked to see if they are formed and functioning properly. The stomach should be located just below the heart and be filled with some amniotic fluid that your baby is constantly swallowing. If there are concerns about your baby's heart it will usually be re-examined at around 24 weeks when the connecting vessels can be more clearly visualised. The main vessels connecting the heart are examined. The heart is examined to see if the four chambers are the appropriate size and connected by valves which can be seen opening and closing with each heart beat. The abdominal wall is checked to ensure that it encases all the internal organs and the abdominal circumference is measured to assist with calculating your baby's size. The spine is checked to make sure that it is fully covered by skin and that the vertebra are forming and in alignment. Clefts of the palate are very difficult to examine and often not detected by ultrasound. Measurements including the head circumference (HC) and biparietal diameter (BPD) are recorded and your baby's face is examined to see if there is any cleft of the lip. The head and its internal structures are examined closely. Areas examined during the ultrasound scan The use of cameras or video equipment is not permitted. If you would like a picture of the scan, please let the sonographer know at the start of the scan. This may be necessary in order to get the most information from the morphology scan of your baby.

The ultrasound works by pulses of sound waves passing from the transducer into the uterus which then bounce harmlessly off your baby, creating echoes. The sonographer will place some ultrasound gel on your abdomen before using the transducer against your skin to create images of your baby. The ultrasound scan is performed by a sonographer who is specially trained to assess your baby. While this can be a very exciting and emotional time it is important to remember that this is a medical examination and the main purpose of the scan is to detect structural abnormalities. The ultrasound scan also provides you with an opportunity to see your baby, often for the first time. It is not a screening test for chromosomal anomalies. It also checks the position of the placenta. It looks for abnormalities in your baby's structural development and growth. Your 18 to 20 week ultrasound scan is also known as the morphology scan or fetal anomaly scan. ![]()
