X-ray examinations

Main X-ray examinations with injection of contrast media:

Angiography scan

An angiography scan is an examination of the blood vessels (veins and arteries). After injecting an iodinated contrast medium intravenously, an angiography scan can be used to view all of the large blood vessels. The examination generally focuses on certain vessels such as the aorta, renal arteries, carotids, etc.

CT Scanner

The scanner or CT tomodensitometry is a medical imaging technology in which the X-rays scan a body or anatomical region in successive slices. This technique has the advantage of highlighting structures that were previously superimposed on traditional radiography films. The computer then reconstructs the images into 2 or 3 dimensions.


Coronary angiography is an examination of the coronary arteries. Here, the iodinated contrast medium is injected directly into the coronary arteries through a catheter.

Oeso-gastro-duodenal transit

These are the different examinations performed on the entire length of the digestive tract with a focus on certain sections (small intestine, duodenum, colon, etc.). Contrast medium is administered before or during the examination.
Barium examinations (with barium as the contrast medium):
-    An examination of oeso-gastro-duodenal transit consists of opacifying the upper part of the digestive tract (oesophagus, stomach, duodenum and small intestine). The contrast medium is taken by mouth.
-    Barium enema is an examination of the lower part of the digestive tract (rectum, colon). The contrast medium is administered by the rectal route and requires careful preparation of the intestine (by washing).

Arthrography / Arthrography scan

Arthrography / arthrography scan is an examination of  bone joints. Here, the contrast medium is injected directly into the joint (knee, shoulder, etc.). Images are produced while the patient lies on an X-ray table (arthrography) or in a scanner (arthrography scan).

Intravenous urography / Uroscan

Intravenous urography / uroscan is an examination of the urinary ducts. In this case a contrast medium is injected intravenously. Images are produced while the patient lies on an X-ray table (urography) or in a scanner (uroscan).
