Twin foetuses. Coloured 3-D ultrasound scan of non-identical twin foetuses at 16 weeks. Non- identical (dizygotic) twins develop when two separate eggs are released from the ovaries and are fertilized. Ultrasound scanning is a diagnostic technique that sends high-frequency sound waves into the body via a transducer. The returning echoes are recorded and used to build an image of an internal structure. Foetal ultrasound scanning is routine during pregnancy. 3-D scanning uses computer technology to return more detailed images than conventional 2-D scans | |
