13-week-old twin foetuses, ultrasound scans

Référence de la vidéo 12371316
Ultrasound scans of 13-week-old twin foetuses. 2D (grey) and 3D (orange) ultrasound scan footage of twin foetuses that have reached the 13th week of development. At this stage the foetuses measure around 7.5 centimetres in length. At around this time, the brain significantly increases in mass and becomes structurally developed. Birth occurs at around 38-40 weeks. Ultrasound scanning uses the reflected echoes of high-frequency sound waves to image an unborn baby. This safe, non-invasive method is used routinely in pregnancy to assess the growth and health of the developing foetus, and detect any abnormalities.
