Computerised Tomography (CT) Scan

What is a CT scan?

A CT scan is a diagnostic imaging test that uses X-rays and digital imaging to produce cross-sectional visuals of your body structure.

How it works

A CT scan uses a large rotating X-ray machine to take images of your body from different angles. These images are combined into cross-sectional images of bones, blood vessels and soft tissues using computer software.

Why do you need a CT scan?

A CT scan is a painless and non-invasive imaging test that produces more detailed information than normal X-rays. It allows doctors to view images of body tissues, including lungs, bones, soft tissues and blood vessels at the same time, to make an accurate diagnosis.

Your doctor may recommend a CT scan to:

  • Locate the blockage or bleed in your brain if you suffered a stroke.
  • Plan and prepare you for surgeries such as awake craniotomy or deep brain stimulation surgery.
  • Identify both normal and abnormal structures to guide radiotherapy, needle biopsies and other minimally non-invasive operations.

Who should not undergo a CT scan?

If you are pregnant, discuss with your doctor to decide if you are suitable for a CT scan.

What are the risks and complications of a CT scan?

A CT scan is a simple and safe test. It carries a low risk of:

  • Exposure to radiation. The radiation dose from a CT scan is small and varies with the type of examination. It has not been shown to cause long-term harm.
  • Harm to unborn babies. Although the radiation from a CT scan is low, your doctor may recommend alternative tests to avoid exposing your baby to radiation.
  • Reactions to the contrast agent. The risk of severe allergic reactions to contrast material is rare, about 1 in 10,000. The risk of leakage of contrast material to surrounding tissues is 0.1%.
