CT Scan

A computerised tomography scan, also called a CT scan, is a type of imaging that uses X-ray techniques to create detailed images of the body. A computer then creates cross-sectional images, also called slices, of the bones, blood vessels and soft tissues inside the body. CT scan images show more detail than plain X-rays do.

A CT scan has many uses. It is used to diagnose disease or injury, as well as to plan medical, surgical or radiation treatment.

Why it’s done

Your healthcare professional may suggest a CT scan for many reasons. For instance, a CT scan can help:

• Diagnose muscle and bone conditions, such as bone tumours and fractures.
• Show where a tumour, infection or blood clot is.
• Guide procedures such as surgery, biopsy and radiation therapy.
• Find and monitor diseases and conditions such as cancer, heart disease, lung nodules and liver masses.
• Check how well certain treatments, such as cancer treatment, are working.
• Find injuries and internal bleeding that can happen after trauma.
