Colour Doppler is a non-invasive test that uses a computer to convert the Doppler measurements into an array of colours. This colour visualization is combined with a standard ultrasound picture of a blood vessel to show the speed and direction of blood flow through the vessel. For this process, the patients don’t require any form of sedatives and the process is not painful. At Samarpan Diagnostic Centre following tests are performed under colour Doppler.
Upper limb Arterial/venous | Lower limb Arterial/venous AV-fistula Arteriovenous | Carotid Doppler di | Renal Doppler
