Scans and ultrasounds

Your GP will discuss with you the different ultrasounds performed during pregnancy. There are three main types of ultrasound offered to pregnant women;

Dating scan

Dating scans are used to confirm how many weeks pregnant you are and your estimated due date, particularly for women who are unsure of the date of their last menstrual cycle or if they have irregular menstrual periods. It is usually performed between 10-13 weeks of pregnancy but can be performed anytime from 6 weeks onward.

Nuchal translucency scan

This type of scan is used to detect the risk of a number of chromosomal abnormalities and is performed between the 11th and 14th week of pregnancy. This scan is not a diagnostic test but will identify the risk of abnormalities such as trisomy 21 (Downs Syndrome), trisomy 18 (Edwards Syndrome) and trisomy 13 (Patau Syndrome) in the growing baby.

Anomaly scans

The anomaly scan is offered in the second trimester, usually between 18-20 weeks of pregnancy. It is used to check for any abnormalities with your baby by identifying the position of the placenta, measuring your baby’s growth and development, checking the umbilical cord and amniotic fluid around your baby and to look at your cervix and uterus.
