It can determine the flow of fluid in foetal trachea and blood flow through its blood vessels, ie arteries and veins, which can then be used to detect conditions of the respiratory system and blood circulation in the foetus.
This test can be performed between 10 to 12 weeks of pregnancy to diagnose abnormalities such as malformations in the foetus.
How much does a Colour Doppler Ultrasound cost?.What do Colour Doppler Ultrasound results mean?.How is Colour Doppler Ultrasound performed during pregnancy?.How do you prepare for a Colour Doppler Ultrasound?.Why is Colour Doppler Ultrasound performed during pregnancy?.Ultrasound colour Doppler also assists in identifying the motion of foetal solid tissues, such as heart walls.Ĭolour Doppler is advantageous over a standard ultrasound procedure because the conventional ultrasound does not show blood flow details in blood vessels of the foetus. These colours help to identify the speed and direction of blood flow through arteries, veins and organs such as heart of the foetus. It is a combination of ultrasound pulse-echo and ultrasound Doppler techniques, which utilises a computer to change the sound waves used in Doppler imaging into different colour to generate a coloured image. Ultrasound pregnancy-colour Doppler is a type of Doppler imaging technique that identifies the direction of movement of blood and its speed in blood vessels.
