Appeared around 40 years ago, computed tomography is a radiology examination that aims to give an image of the body in two or three dimensions, depending on the settings. It's a simple, exact, and quick-to-set-up examination which is frequently applied nowadays.
Computed tomography, often known as a scanner, is a device that uses low doses of X-rays to examine a specific part of the body.

A CT scan may be recommended by your doctor to help :
- Study the brain, spine, thorax, abdomen or pelvis
- Identify the size, shape and location of tumors
- Find out how far the cancer has spread and whether it is in nearby organs and tissues
- Damage the cells in the body
- Increase the possibility of cancer developing
- Cause an allergic reaction
- X-ray
- MRI
- Between 30 and 60 minutes
