The purpose of the mid-pregnancy scan (sometimes known as a fetal anomaly scan) is to check your baby’s health and development. It’s offered between 18 and 21 weeks of pregnancy.
An anomaly scan, also known as a mid-pregnancy scan, takes a close look at your baby and your womb (uterus).
The person carrying out the scan (sonographer) will check that your baby is developing normally, and look at where the placenta is lying .
