Ultrasound is one of the most widely used diagnostic imaging techniques in modern healthcare. It produces real-time images of internal organs and tissues using high-frequency sound waves. Apollo Adlux Hospital, Kochi, offers advanced ultrasound and Colour Doppler imaging to support the evaluation of abdominal, vascular, obstetric, cardiac, musculoskeletal and other medical conditions.Because standard diagnostic ultrasound does not use ionising radiation, it is frequently used across different age groups, including pregnant women and children, when clinically appropriate.

How Does an Ultrasound Scan Work?

During an ultrasound examination, a medical professional applies a clear gel over the area being studied. A handheld device called a transducer is moved across the skin. The transducer sends sound waves into the body and receives the returning echoes. These signals are converted into real-time images that can be examined by the radiologist or treating doctor. Depending on the clinical requirement, an ultrasound may be performed externally or with a specialised internal probe.

What Can an Ultrasound Scan Detect?

Ultrasound may be used to examine:

•            Liver, gallbladder and bile ducts
•            Kidneys and urinary bladder
•            Pancreas and spleen
•            Uterus and ovaries
•            Thyroid gland
•            Breasts and superficial tissues
•            Muscles, tendons and joints
•            Prostate and testicles
•            Developing baby during pregnancy
•            Fluid collections, cysts and selected lumps

It may also guide procedures such as biopsies, fluid drainage and needle placement.

What Is a Colour Doppler Scan?

Colour Doppler is a specialised ultrasound technique that assesses the movement and direction of blood through arteries and veins. Colour coding is used to represent blood flow, helping doctors evaluate circulation and identify possible abnormalities. A Doppler scan may provide information about the speed and pattern of blood flow in a particular vessel.

Conditions Evaluated Through Colour Doppler

Colour Doppler ultrasound may be recommended to assess:

•            Narrowing or blockage of arteries
•            Blood clots in the veins
•            Deep vein thrombosis
•            Reduced blood supply to the limbs
•            Carotid artery disease
•            Varicose veins and venous insufficiency
•            Aneurysms
•            Blood flow in transplanted organs
•            Blood circulation in the placenta and umbilical cord
•            Selected scrotal and testicular conditions
•            Blood supply within certain tumours or swellings

A vascular Doppler examination can help doctors detect circulatory problems and plan further investigations or treatment.

Common Types of Doppler Ultrasound

Carotid Doppler

A carotid Doppler evaluates the arteries in the neck that supply blood to the brain. It may be recommended for patients with symptoms or risk factors associated with stroke.

Arterial Doppler

An arterial Doppler assesses blood flow through the arteries of the arms or legs. It may help identify reduced circulation caused by narrowing or blockage.

Venous Doppler

A venous Doppler is commonly used to look for blood clots, particularly in patients experiencing leg swelling, pain, warmth or redness.

Obstetric Doppler

During selected pregnancies, Doppler ultrasound may be used to evaluate blood flow through the umbilical cord, placenta and certain fetal vessels.

Benefits of Advanced Ultrasound and Colour Doppler

The major advantages include:

•            No ionising radiation
•            Real-time imaging
•            Non-invasive examination in most cases
•            Evaluation of both structure and blood circulation
•            Wide range of clinical applications
•            Usefulness in guiding selected procedures
•            Usually minimal preparation and recovery time

The duration of the scan will depend on the body part and the complexity of the examination.

How Should Patients Prepare?

Preparation varies according to the scan. For example, patients undergoing an abdominal ultrasound may be asked to fast for several hours. A pelvic ultrasound may require a full bladder.

Patients should follow the specific instructions provided while booking the scan and bring previous medical records or imaging reports when available.
