How Is a USG Colour Doppler Test Performed?

• The patient lies or sits in a suitable position.
• The area to be examined is exposed.
• A clear ultrasound gel is applied to the skin.
• A handheld ultrasound probe is moved over the required area.
• Standard ultrasound images are obtained.
• Doppler technology is used to assess blood flow.
• The patient may be asked to change position during the examination.
• The test usually takes around 20 to 45 minutes, depending on the area being examined.

Preparation for USG Colour Doppler

Patients may be advised to:

• Wear comfortable clothing.
• Avoid applying creams or oils to the area being examined.
• Follow fasting instructions for selected abdominal Doppler examinations.
• Inform the healthcare professional about previous surgery or vascular procedures.
• Bring previous ultrasound, CT, MRI, or other medical reports.
• Follow any specific instructions provided by the imaging centre.
