Molecular Diagnostics and Therapy is an NABL & NABH Accredited Diagnostics Centre and offers radiology and diagnostic imaging services with cutting-edge equipment and Bilateral Colour Doppler Ultrasound services. Colour Doppler is an interactive imaging technique which utilises ultrasound to assist in the assessment of blood flow in blood vessels and to the evaluation of selected abnormalities of the blood vessels. The bilateral exam involves the examination of similar body structures on both sides of the body, which helps the doctor compare blood flow and, if needed, devise a plan for further testing.

About Colour Doppler (Both)

Bilateral Colour Doppler Ultrasound is a radiological investigation that can evaluate the flow of blood in the vessels, bilaterally (on both sides of the body). This can be done to both arms, both legs, or other paired body parts as directed by the doctor. This type of test involves "normal" ultrasound as well as Doppler, a technique that allows the doctor to see blood vessels and identify the direction and flow of blood. It may be recommended for scenarios such as swelling, pain, when there is any suspicion of blood clots, when there are circulatory problems, or when there are issues or a history of problems. The type of Doppler exam (arterial, venous, etc.) as well as the specific site of interest will have to be determined by the prescription.

What is Colour Doppler (Both)?

A technique that directs high-frequency sound waves into the body to provide images of the internal blood structures and to measure blood flow in the blood vessels. The Directional Blood Flow is supplied by colour coding, and other flow velocity measurements are provided by Spectral Doppler. The Bilateral studies involve analysis of the two similar structures on both sides with the same protocol. Comparative evaluation of both sides may also show differences in amount of blood flow and/or differences in the appearance of the vessels or other vascular findings. The time required for the scan depends on the area to be scanned as well as the complexity of the measurement.

Common Reasons for Colour Doppler (Both)

• Suspected Blood Clots: Venous study is possible to help assess suspected deep/venous thromboses, when clinically indicated, in a bilateral manner.
• Limb Swelling: Assesses venous circulation if both or one limb is swollen.
• Pain or Tenderness: Can aid in the investigation of symptoms which may relate to vascular abnormalities.
• Circulation Problems: Evaluates blood flow when decreased or abnormal blood flow is suspected.
• Bilateral Arterial Study: This could assist in finding certain areas of narrowing/obstruction of the vessels.
• Follow-Up for Vascular Conditions: Facilitates follow-up for some identified vascular conditions.
• Post-Surgical Assessment: May be recommended as an assessment of blood flow following certain surgeries.
• Abnormal Vascular Findings: Helps to investigate any possible abnormal vascular changes found during the physical examination or in previous MRI.
• Bilateral Vascular Assessment: Provides information about vessels on both sides of the body (if a comparison is requested).

Conditions Evaluated

Venous Obstruction

Scientific ultrasound using Doppler techniques may be useful to identify that flow is not taking place or flow is decreased if there are accessible veins. If vessels are suspected of an obstruction, more imaging might be necessary if they are not able to be fully assessed by ultrasound.

Arterial Narrowing and Blockage

An arterial Doppler may also be ordered to help determine the flow pattern, and then subsequently use the Doppler to define a zone of restriction or narrowing. Depending on the prescribed protocol, the vessels to be considered are the ones mentioned in the protocol.

Venous Insufficiency and Reflux

Venous reflux can be identified by conducting a venous reflux study, which checks for any abnormal venous reflux that could be occurring due to venous valve dysfunction. This could assist in establishing heavy, swollen, or varicose leg symptoms.

Differences in Bilateral Blood Flow

A bilateral evaluation with similarly sized vessels on either side could help to identify flow pattern inconsistencies or vessel flow pattern traits. These findings, along with symptoms and history, are used to make a diagnosis.

Post-Treatment Vascular Changes

After treatment or surgery, some vascular conditions might be assessed using a bilateral Doppler ultrasound. The protocol will be decided based on the procedure and the question.

Other Vascular Abnormalities

The exam may be done in various locations within the body and can be used to evaluate some blood flow abnormalities called vascular malformations.

Book Your Colour Doppler (Both)

Should your doctor have recommended you have an examination of two areas (bilateral) on Colour Doppler, Molecular Diagnostics and Therapy need to check whether the areas are in the body to be examined are both arteries, both veins, or other Doppler body areas. Please bring a prescription, previous Doppler reports, and medical records, if available, to determine a proper examination procedure to follow.
