Low-Dose Computed Tomography (CT)

What is a CT Scan?

Computed Tomography (CT) is an x‐ray examination performed with a computerised x‐ray scanning machine. The CT scan looks at the body in cross section. To produce images, a narrow beam of x‐rays is rotated around the part of your body to be examined. The x‐ray beam is monitored and recorded by an array of sensitive detectors which channel the signals to a large computer within the scanner. The computer then generates a visible image of the cross section of the body region being examined.


Please ensure the following steps are followed. They will serve to prepare you for your examination and/or procedure.

  • Contrast CT requires appointment for this examination
  • Depending on the type of CT examination, you may be asked to fast or to drink oral contrast prior which will require you to arrive earlier
  • Hairclips and all items of jewellery will need to be removed as to avoid interfering with the exam
  • You will be asked to sign a consent form
