What does a Doppler test check for?
A Doppler test is used to detect blood flow. It shows whether a pulse is present and whether there is blood flow to a limb. It can diagnose or help to manage conditions such as peripheral arterial disease (PAD) or diabetic foot ulcer.
What are three types of Doppler displays?
There are three main types of Doppler systems: continuous wave, pulsed wave, and power Doppler.
What are the two types of Doppler ultrasound?
The three basic types of Doppler ultrasound are:
- “Bedside” or continuous wave Doppler. This type uses the change in pitch of the sound waves to provide information about blood flow through a blood vessel.
- Duplex Doppler.
- Colour Doppler.
What is the principle of Doppler?
Doppler echocardiography is based upon the changes in frequency of the backscatter signal from small moving structures (ie, red blood cells) intercepted by the ultrasound beam. The principles of Doppler echocardiography will be reviewed here.

How do they do a Doppler test on your legs?
During the exam:
- A water-soluble gel is placed on a handheld device called a transducer. This device directs high-frequency sound waves to the artery or veins being tested.
- Blood pressure cuffs may be put around different parts of the body, including the thigh, calf, ankle, and different points along the arm.
What is Doppler ultrasound radiology?
A Doppler ultrasound uses sound waves to look at blood vessels and analyze blood flow. This test allows physicians to see if there’s a reduction in blood flow to determine a variety of diseases or complications.
What is the difference between echo and Doppler?
An echocardiogram uses high frequency sound waves to create an image of the heart while the use of Doppler technology allows determination of the speed and direction of blood flow by utilizing the Doppler effect.
What is Doppler ultrasound and its types?
Colour Doppler uses standard ultrasound methods to make a picture of a blood vessel. A computer changes the Doppler sounds into colours that are overlaid on the image of the blood vessel. These colours show the speed and direction of blood flow through the vessel. Power Doppler is a special type of colour Doppler.
What is the cost of Doppler test for legs?
The average cost of Venous Doppler Lower Limb in India is ₹ 1440 if booked through us. The average market price in India is much higher at ₹ 4400. LabsAdvisor is making diagnostic testing more affordable.
What do you wear to a Doppler scan?
The Doppler test involves applying a blood pressure cuff to your arms and legs in turn. Wear something with short or loose sleeves and loose fitting trousers so that the trouser legs can be rolled up. You will also be asked to remove your socks/ tights/stockings and shoes.
What is the cost of Doppler?
It is also known as Doppler pregnancy ultrasound, fetal doppler, and USG Color doppler pregnancy. A Doppler pregnancy scan measures the blood flow through the umbilical cord and around different organs of the baby’s body, such as the brain and heart. Doppler pregnancy test cost ranges from Rs 1500 to Rs 3000 in India.
