Computed Tomography (CT)  is a non-invasive medical test to help physicians diagnose and treat medical conditions. The new

state-of-the-art CT suite at The Scarborough Hospital (TSH) uses technology that offers up to 50 per cent less radiation.

CT scanning combines special x-ray equipment with sophisticated computers, and has the unique ability to produce images of soft tissue, bones, organs and blood vessels in the head, neck, chest, abdomen, pelvis and extremities. As a result, CT scans are more precise and reveal more information than an x-ray.

The exam is performed by an x-ray technologist, who has had special training in CT scanning, and the images are analyzed and reported on by a radiologist.

What We Offer

CT scanning at TSH includes:

  • Imaging to promptly identify concerns with:
    • lungs
    • heart and blood vessels
    • liver
    • spleen
    • kidneys
    • head and neck region
    • chest
    • abdomen
    • pelvis
    • extremities
  • Guided biopsies and other procedures (abscess drainages and/or minimally invasive tumours)
  • Determining results from surgery (organ transplants and/or gastric bypasses)

Some of these exams require intravenous injection of contrast media, or oral or rectal contrast. If this is required, patients are informed when they book their appointment.
