When is it indicated?
The CT scan makes it possible to locate a lesion, measure its extent and monitor its progression during treatment. It is an essential tool for the medical team to adapt care at every stage.
With a contrast agent injection, the CT scan visualizes the blood vessels in detail. It is requested urgently when a clot in the lungs or damage to the aorta is suspected.
In cases of persistent cough, shortness of breath or an abnormality on an X-ray, the chest CT scan finely examines the lungs and the region between them to determine the cause.
The CT scan explores all the organs of the abdomen in a matter of moments. It helps explain abdominal pain, characterize an abnormality seen on ultrasound or look for an infection.
The CT scan detects stones in the kidneys and urinary tract with great reliability. Dual-energy technology can even help determine their nature, which guides treatment to prevent recurrence.
When a fracture is difficult to analyze on a plain X-ray, the CT scan provides three-dimensional images of the bones. It is also used to check the condition of the skeleton as part of a cancer workup.
Cardiac CT makes it possible to examine the arteries of the heart without any intervention and to assess the presence of calcium deposits, helping the cardiologist estimate the health of the coronary arteries.
Thanks to its speed, the CT scan is the examination of choice in emergency situations: it quickly assesses the situation after an accident, in the presence of signs of stroke or sudden abdominal pain.
