Ultrasound is a morphological and dynamic examination. Sometimes, an additional Doppler ultrasound – an absolute functional exploration coupled with ultrasound investigation – is relevant to explore the vascularization of organs.

Ultrasonography shows organs through the use of ultrasound. A probe emits ultrasounds. The latter cross tissue and come back in the form of an ultrasound depending on obstacles encountered. The result is a signal which is collected and analysed by a computer system. An image is then sent directly to a video screen.

“It is a non-radiating examination widely used in children or as an alternative to MRI.”

Progress of the procedure


The bladder must be full for pelvic, abdominal-pelvis, urinary organs and prostate ultrasounds. Drink ¾ litre(4 glasses)of water one hour before the examination. Do not urinate. However, if the bladder is too full, it can be partially emptied.

Have fasted for 3 hours for abdominal ultrasounds. Medicines can however be taken with water.


The patient is installed in the ultrasound room. The medical staff tells him/her what clothing to remove. The radiologist spreads a water-based gel on the part of the body to be examined in order to avoid any interposition of air.

An image is visible on a video screen according to the movements of the ultrasound probe which goes from one organ to another. Benchmark images are taken during the examination.

Once the ultrasound is finished, the gel is removed with absorbent paper.


There are no contraindications to ultrasound.
