Computed Tomography (CT)

Computed Tomography (CT) imaging utilises a series of images (using ionizing radiation), acquired from different angles around the body and uses computer processing to create cross-sectional and three dimensional (3D) images of bones, blood vessels and soft tissues within the body.

Union Imaging and Healthcheck Centre has installed state-of-the-art: GE Revolution CT scanner, which combines the most advanced computed tomography technologies into one CT scanner. It produces 256 slices with high definition Gemstone Detector, 16cm body coverage, and is able to cover an entire organ in a single rotation. This design enables better and more detailed image acquisition accurate diagnosis, and marked reduction in radiation.

Services

  • Routine high definition imaging of head, thorax, abdomen, pelvis, spine, and extremities
  • Low dose thorax screening
  • CT Colonography (Virtual colonoscopy)
  • Angiogram (Coronary, Head and Neck, Lower limb, etc)
  • Perfusion and Dynamic scan (brain, heart, and liver, etc)

Features of Revolution CT Scanner

  • Revolution CT has 16cm wide detector with outstanding performance in many areas, including CT Coronary angiogram where the heart can be imaged in a single heartbeat, irrespective of heart rate.
  • Enables whole organ diagnostic and perfusion scan, such as liver dynamic scans and brain perfusion scans.
  • Fast table speed further reduces the examination time, helping to reduce the volume of injected contrast.
  • With the use of new technology such as ASiR-V and the high definition Gemstone detector, the radiation dose is significantly reduced without compromising image quality.
  • The 80cm-wide bore, provides a more comfortable and anxiety-free environment during the scan for our clients.

Preparations
  • Keep fasting for at least 4 hours prior to CT contrast examinations
  • Avoid caffeinated products for 12 hours prior to the appointment for CT coronary angiography
  • For diabetic clients, stop metformin on the day of examination and the following 48 hours
  • Inform our staff if clients have allergic history to contrast medium
  • Female clients should inform our staff if they are pregnant or may be pregnant before the examination
Procedures
  1. Clients will be asked about their medical history.
  2. Clients will lie on the scanning couch. The couch will move into the large ring-shaped machine slowly
  3. Keep still during the examination to ensure the best image quality
  4. Clients may be asked to follow the breath-holding instruction
  5. The whole procedure will be monitored by radiographers. If clients are feeling unwell, clients may seek help from our staff
  6. The examination takes around 15-30 minutes. The time required may be longer if clients are having CT coronary angiography
  7. Clients will need to wait for 15-20 minutes after the examination. Clients can leave if no sign of allergy is shown
