Doppler Scan – Advanced Vascular Imaging
At Akshar Imaging Centre, we offer advanced Doppler Scan in Ahmedabad to evaluate blood flow in arteries and veins throughout the body. This safe, non-invasive, and radiation-free test uses high-frequency sound waves and color Doppler technology to assess circulation, detect blockages, and diagnose vascular conditions early.
Our expert radiologists use state-of-the-art ultrasound systems to measure blood flow velocity and direction, helping doctors diagnose deep vein thrombosis (DVT), varicose veins, arterial blockages, carotid artery disease, and other circulatory problems with precision.
What Is a Doppler Scan?
A Doppler Ultrasound (or Color Doppler Scan) is a specialized type of ultrasound that evaluates the movement of blood through vessels using sound wave reflections. It visualizes how blood flows through arteries and veins, showing direction, speed, and potential obstructions.
It is widely used for evaluating blood clots, arterial narrowing, varicose veins, peripheral vascular disease, and to monitor fetal blood flow during pregnancy. The test is completely safe, painless, and does not use radiation or contrast dyes.
Types of Doppler Scans
- Carotid Doppler: Evaluates blood flow in neck arteries supplying the brain.
- Venous Doppler (Lower or Upper Limb): Detects clots, varicose veins, or venous insufficiency.
- Arterial Doppler: Assesses arterial blockages or narrowing in arms and legs.
- Abdominal Doppler: Examines abdominal blood vessels, liver, or kidneys.
- Obstetric / Fetal Doppler: Monitors blood flow in the umbilical cord and placenta during pregnancy.
Why It’s Performed / Common Indications
- Leg pain, swelling, or varicose veins
- Suspected deep vein thrombosis (DVT)
- Numbness, tingling, or weakness due to poor circulation
- Carotid artery narrowing or stroke evaluation
- Peripheral arterial disease (PAD)
- Abdominal or renal artery stenosis
- Monitoring after vascular surgery or stent placement
- Evaluation of fetal blood circulation during pregnancy
Preparation
- Usually, no special preparation is needed for most Doppler scans.
- For abdominal Doppler, fasting for 6–8 hours may be required.
- Wear loose, comfortable clothing.
- Avoid applying lotions or oils before the scan.
- Inform the technologist about any recent vascular procedures or ongoing medication.
Procedure
- You will lie comfortably on the examination bed.
- A warm, water-based gel is applied to the area being examined.
- The technologist moves a handheld transducer over the skin to capture real-time color images.
- The Doppler function measures blood flow speed and direction using sound wave reflections.
- The procedure is painless, safe, and takes around 20–30 minutes, depending on the region scanned.
What Happens Next (Interpretation)
- Presence of clots (DVT) or venous insufficiency
- Arterial narrowing, blockages, or plaques
- Blood flow velocity and direction
- Signs of aneurysm or vascular abnormalities
- Fetal and placental blood flow in pregnancy Doppler studies
A detailed report is prepared and sent to your referring doctor for diagnosis and treatment planning.
