Computerised Tomography (CT) Scan

  • What is a Computerised Tomography (CT) Scan?

    A computerised tomography or CT scan is an examination that uses a digital imaging system and x-rays to take cross-sectional images of the body. This examination can provide clear images of various body structures including bone, blood vessels and soft tissues, all at once. The resulting images contain detailed information that can help doctors diagnose many conditions.

    It is a relatively simple and non-invasive test. You will be asked to lie very still on your back on a table that moves in and out of a movable tunnel that contains the x-ray scanner. There are preparations needed before going for your CT scan appointment. You will need to avoid eating for about 4 hours before your scheduled CT scan if an intravenous contrast (to highlight blood vessels and tissues in the scan) needs to be injected. You also need to tell staff of any allergies you may have or medications you are taking.

  • Your doctor may advise a CT scan to provide detailed views of many types of tissue, including the lungs, bones, soft tissues and blood vessels. If you have suffered a stroke, a CT scan can find the blockage or bleeding in the brain that caused the stroke. It also allows your doctor to find both normal and abnormal structures in a painless, non-invasive and accurate manner.

    A CT scan helps in the planning and preparation of certain surgeries including awake craniotomy (brain surgery to remove brain lesions) and deep brain stimulation surgery. It is also useful in the planning and guiding of radiotherapy (cancer treatment), needle biopsies and other minimally invasive operations.
