Vascular Imaging

Doppler Ultrasound - Doppler Ultrasound uses special technology to allow the sonographer to study the blood flow in your arteries and veins. The most common studies performed are the arteries in the neck (carotid arteries). These supply blood to your brain and face. Other common vessels examined are the renal arteries supplying your kidneys and the veins and arteries in the legs looking for blockages or clots. Often during the Doppler scan you will hear strange noises as the signals from the flowing blood are converted to sound.

CT Angiography - A computed tomography technique used to visualise arterial and venous vessels throughout the body. This ranges from arteries serving the brain to those bringing blood to the lungs, kidneys, arms and legs. The scan is performed simultaneously with a high speed contrast media (dye) injection. Compared to catheter angiography, which involves placing a sizable catheter and injecting contrast material into a large artery or vein, CT Angiography is a much less invasive and more patient-friendly procedure. The contrast material is injected into a small peripheral vein by using a small needle or cannula. This type of examination has been used to screen large numbers of individuals for arterial disease.
