Colour Doppler is a specialised ultrasound test that uses computer processing to convert sound waves into different colours, thereby showing the speed and direction of blood flow in arteries and veins. It combines conventional ultrasound imaging with Doppler technology. Doctors may recommend colour Doppler when there are symptoms such as limb swelling, pain, changes in skin colour, suspected blood clots, reduced circulation, or other vascular concerns.
Dr. Yugal Goyal provides a high-quality Colour Doppler test in Siliguri. His cutting-edge diagnostic centre offers advanced imaging tests along with patient-centric care. The test is non-invasive and does not involve radiation. The exact type of Doppler examination depends on the blood vessels or the medical issue being evaluated.
A Colour Doppler test is an ultrasound-based imaging test that evaluates blood flow through blood vessels. While a conventional ultrasound images body structures, Doppler adds information about how blood moves through blood vessels.
During the examination, an ultrasound probe transmits sound waves into the body. The movement of blood cells changes the frequency of the reflected sound waves. The ultrasound system processes these changes and presents information about blood flow, often using colour overlays on the ultrasound image.
Colour Doppler can help doctors identify blood clots, vessel narrowing, vessel blockage, abnormal blood flow, reduced circulation, etc. However, it does not diagnose every vascular condition on its own, but provides important imaging information that can support clinical diagnosis. The various types of conditions that can be detected by a Doppler Ultrasound in Siliguri are –
when a doctor suspects a deep vein thrombosis (DVT) or some other venous clot, a venous Doppler is commonly used. It evaluates veins and blood flow.
Doppler examination can assess blood flow patterns and velocities that may indicate narrowing.
A Doppler test can help determine whether blood is flowing through the examined vessel and whether an obstruction may be present.
Changes in blood flow direction, velocity, or pattern may provide clues about underlying vascular abnormalities.
Ultrasound can help identify plaques and other structural changes in the vessel wall. Doppler assessment can also evaluate their effect on blood flow.
Arterial Doppler helps assess circulation when blood supply to a limb or some other area is reduced.
The various types of Colour Doppler scans in Siliguri are Arterial Doppler, Venous Doppler, Lower Limb Doppler, Upper Limb Doppler, Carotid Doppler, etc. Different Doppler examinations focus on different blood vessels and parts of the body. The above types are explained below in detail -
It evaluates blood flow through arteries. Doctors recommend it when they suspect reduced circulation, arterial narrowing, or obstruction.
It examines blood flow through veins. It is used to investigate venous obstruction or a suspected blood clot.
It evaluates blood vessels in the legs. It is used to assess either arteries or veins, depending on the reason for the examination.
It examines carotid arteries in the neck, which supply blood to the brain. It can assess the structure of arteries, including plaque-related changes and narrowing, and evaluate blood flow characteristics.
It is performed during pregnancy when the obstetrician needs additional information about blood flow between the mother, placenta, and the developing baby.
A Colour Doppler is a simple, non-invasive ultrasound examination that uses sound waves to create images of blood vessels and assess how blood is flowing through them. The procedure is comfortable and does not involve injections or ionising radiation.
The Doppler Ultrasound Test in Siliguri involves the following steps -
Preparation for the test includes following the diagnostic centre's instructions, informing the team about the medications that the patient is taking, sharing relevant medical history, wearing suitable clothing, and carrying previous reports, etc. However, the preparation depends on the blood vessels and the body area being examined. The preparation steps for the Colour Doppler Test in Siliguri are explained below –
the patient may ask for any specific preparation requirements when scheduling the Colour Doppler test.
certain abdominal or pelvic vascular Doppler tests may require the patient to avoid foods and drinks for a specified period before the test.
if the patient is taking any medicines, this must be reported to the healthcare team.
inform the healthcare professional about previous vascular problems, blood clots, surgeries, or other relevant conditions.
if the patient has an earlier ultrasound, Doppler, CT, MRI, or other relevant reports, they must be brought along. This helps the doctor in comparing the findings when appropriate.
the patient must wear clothing that provides easy access to the area being examined.
A general Colour Doppler test in Siliguri may range between ₹1400 - ₹2500. However, it may vary depending on the type of examination, the body part being assessed, the number of vessels being examined, and the diagnostic centre. Also, specific examinations such as pregnancy fetal Doppler or lower limb venous Doppler may have different charges. The table below shows the list of prices for different types of Colour Doppler tests -
| Colour Doppler Examination | Approximate Cost in Siliguri |
|---|---|
| General Colour Doppler | ₹1400 – ₹1800 |
| Lower Limb Venous Doppler | Around ₹2500 |
| Colour Doppler for Pregnancy/ fetal scan | Around ₹2100 |
| Arterial Doppler | ₹1500 –₹2500 |
| Venous Doppler | ₹1500 –₹2500 |
| Carotid Doppler | ₹1500 –₹2500 |
Disclaimer - These are indicative ranges, not fixed prices. The actual charge can vary according to the centre, examination area, whether one or both sides are scanned, and the complexity of the study. Patients should confirm the current price and the exact Doppler examination required with the diagnostic centre before booking, as charges can change.

A Colour Doppler test is used to examine blood flow through arteries and veins. It assesses how effectively blood is moving through the body’s blood vessels. It combines ultrasound imaging with Doppler technology to provide information about the direction, speed, and pattern of blood flow. This helps doctors investigate suspected vascular problems and monitor certain conditions.
A Colour Doppler test is generally painless and non-invasive. It uses sound waves to examine blood vessels and assess blood flow. Thus, it does not involve radiation or injections.
A colour Doppler test in Siliguri usually takes around 20 to 60 minutes. However, the exact duration depends on the type of examination and the number of blood vessels being assessed. Simple Doppler examinations may take around 20 to 30 minutes, while limb Doppler may take 30 to 45 minutes.
Whether you can eat before a Colour Doppler test depends on the type of examination and the body area being assessed. Many Doppler tests, particularly of the arms and legs, do not require fasting.
