Ultrasound duplex

A duplex ultrasound is an examination where ultrasound is used in combination with a color doppler. An ultrasound uses sound waves to look inside the body. A color doppler measures the flow rate of blood. A distinction is made between a venous duplex and an arterial duplex.

ARTERIAL DUPLEX

Arterial duplex is an ultrasound showing blood flow in the arteries. The examination can be performed to detect narrowing of the blood vessels as a result of arteriosclerosis. The purpose of a duplex examination is to assess arteries in the neck, abdomen or legs (arterial duplex). With a duplex examination, the arteries are assessed for their patency and narrowing or occlusion can be detected. The main artery (aorta) can also be checked for dilations (aneurysm aorta). Main arteries in the legs are assessed for the functioning of the valves in the veins. If these valves are not functioning properly, there is venous insufficiency. Also, a duplex examination can determine the origin of varicose veins.

Course of the examination

Ultrasound uses high-frequency sound waves that are undetectable to the human ear. The sound waves are sent into the body through a transducer (a small probe) placed directly on the skin. It is a device that can send and receive sound waves. To receive the sound properly, a gel is applied on the skin. This gel provides better conduction. The transmitted sound is reflected (echoed) back to the transducer by the organs in the body. The received signal is converted into an electrical signal by a computer. This signal forms a grayscale image that is visible on the screen. The examination is painless and no X-rays are used.

The radiologist who performed the examination makes an initial interpretation of the images during the examination. After the final interpretation, he sends a report to the doctor who requested the examination. Only this doctor can discuss the results with you.

For an ultrasound you must always make an appointment at the radiology department (tel. 011 69 92 75).
