The following are tests carried out to confirm the diagnosis of carotid artery disease.
Carotid Duplex Ultrasound
An imaging procedure that uses high-frequency sound waves to view the blood vessels in the neck and to determine the presence of narrowing in the carotid arteries. This study is recommended in anyone with heart disease and anyone over the age of 60.
This is a procedure to image the carotid artery. It can be done via a specialised CT scan (CT Angiography) , MRI scan (MR angiography) or via a catheter angiogram. This is an invasive imaging procedure that involves inserting a catheter into a blood vessel in the arm or leg, and guiding it to the carotid arteries with the aid of a special x-ray machine. Contrast dye is injected through the catheter so that x-rays of your carotid arteries are taken.
