Computerised Tomography (CT) Scan

  • What is a Computerised Tomography (CT) Scan?

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

    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 tiltable tunnel that contains the x-ray scanner. There are preparations needed to be done before you attend your CT scan appointment. You need to fast for about 4 hours before your scheduled CT scan if an intravenous contrast (to highlight blood vessels and tissues in the scans) needs to be injected. You also need to tell the staff of any allergies you may have or medications you are taking.

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

    A CT scan helps in the planning and preparation of some 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.
