Ultrasound (Sonogram)

Fast personalised medical care

Sonography is a diagnostic medical imaging technique that uses ultrasound waves to capture images. Theses waves come back through the different structures as "echoes" with different amplitudes based on the organs being passed through. Images are then generated that allow for analysing the size, content and function, etc.

How the test is performed

First a gel, which acts a conducer, is placed on the skin. Then a transducer or echo probe is used to visualize the images on a screen. These images are recorded for future study and for saving any findings made. In gynaecological or prostate studies, the wave is introduced through the anus or vagina so as to correctly study these organs.


Preparation and advice

Sonograms are painless and totally harmless, even during pregnancy and childhood. A sonogram can be repeated as many times as necessary without endangering your health.

You will be informed the day before if any prior preparation is needed, depending on the area of study. For example, for sonograms of extremities, no prior preparation is needed, but for an abdominal ultrasound, you have to come on an empty stomach but with a full bladder, if possible. Wearing comfortable clothes is recommended.
