Doppler Study of Blood vessels are done by Ultrasound machine, with a special technique known as Doppler and Colour Doppler, which measures the velocity of blood flow inside the blood vessels. This is helpful to study the blood flow inside blood vessels and diagnose conditions such as narrowing of the blood vessels.
Most commonly Doppler studies are done for Carotid arteries (blood vessels of neck, that supply blood to brain), Renal Artery (blood vessel that supply blood to kidneys) and Peripheral Doppler (blood vessels that supply blood to legs - both arteries and veins).
Doppler study of all vessels are done in Pokhara Clinic with latest state of the art USG/ECHO machine from Siemens _ Accusox X300. Doppler study of Renal Artery is done in Kathmandu Clinic by Hitachi HUB 5500 USG/ECHO machine.
