Doppler Ultrasound in Palamós

What Is Doppler Ultrasound?

Doppler ultrasound is an imaging technique that uses sound waves to assess the flow of blood through the blood vessels. It combines conventional ultrasound imaging with the Doppler effect to show the speed and direction of blood flow in real time.

This test is essential for the diagnosis of vascular diseases and makes it possible to detect obstructions, narrowings, clots and other abnormalities of the circulatory system in a non-invasive and painless way.

Types of Doppler Ultrasound

Arterial Doppler

It assesses blood flow in the arteries of the limbs, the neck (carotid arteries) and the abdomen. It can detect stenosis (narrowings), atheromas (cholesterol plaques) and aneurysms that can increase the risk of stroke or ischaemia.

Venous Doppler

It studies the venous system, especially in the lower limbs, to diagnose deep vein thrombosis (DVT), chronic venous insufficiency and varicose veins. It is an essential test in patients with swollen legs, pain or a risk of thromboembolism.

Carotid Doppler

A specific examination of the carotid arteries in the neck to assess the risk of cerebral stroke. It detects atheroma plaques and measures the degree of stenosis to determine whether preventive treatment is necessary.

Cardiac Doppler Echo

Assessment of blood flow within the cardiac chambers and the heart valves. It complements the echocardiogram to diagnose valve disease, insufficiencies and other heart conditions.

Indications

Doppler ultrasound is recommended in patients with limb pain, swollen legs, varicose veins, a history of thrombosis, suspected carotid stenosis, arterial hypertension, diabetes and as part of the assessment of cardiovascular risk.

Preparation and Procedure

Doppler ultrasound does not require special preparation in most cases. The test lasts between 20 and 45 minutes, is completely painless and the results are available immediately.
