PATIENT INFORMATION - Diagnosis

Ultrasound  
Ultrasonography is a technique used for visualising internal body structures, including blood vessels, and also for examining blood flow through the vessels. It is used to diagnose aneurysms, blocked arteries, diseased veins and blood clots. It provides images in real-time, does not use harmful radiation, has no known side-effects and is painless.

  Fast from midnight for abdominal scans. You can however have unlimited water and take all medications with water. If having a test for varicose veins do not wear compression stockings for 24 hours. Do not apply moisturisers on the day of the examination.
Angiography  
Angiography is a technique used to provide additional information about the inside of blood vessels. It involves injecting a contrast agent into the blood vessel, usually through the groin, and imaging using X-rays. Potential problems include bleeding or bruising at the injection site, or an adverse reaction to the contrast.

  Prior to an angiogram patients need their kidney function checked. When confirming with the Hospital your arrival time enquire regarding the fasting requirements. The procedure and recovery takes about six hours. You are not permitted to take public transport after the procedure and will need to be supervised for two hours after returning home.

Computed tomography (CT) Scan  
CT scanning uses computer-processed x-rays to produce images of the scanned area. Similar to angiography it usually involves injection of contrast and patients need their kidney function checked.
