What is a CAT Scan ?

Computed tomography of the body uses sophisticated x-ray technology to help detect a variety of diseases and conditions. CT scanning is fast, painless, non-invasive and accurate. Computed tomography, more commonly known as a CT or CAT scan, is a diagnostic medical imaging test. This method is different than traditional x-rays as it generates cross-sectional images, which are reformatted in multiple planes. They can even generate three-dimensional images. These images can be viewed on a computer monitor, or transferred to a USB.

CT images of internal organs, bones, soft tissue and blood vessels provide greater detail than traditional x-rays, particularly of soft tissues and blood vessels. Using specialized equipment and expertise to create and interpret scans of the body,

CT scans can detect:

  • Cancer
  • Cardiovascular Disease

  • Appendicitis
  • Trauma
  • Musculoskeletal Injury

Frequently Asked Questions

Computed Tomography

  • How do I prepare for a CT exam?

    Tell your doctor if there’s a possibility you are pregnant and discuss any recent illnesses, medical conditions, medications you’re taking, as well as any allergies you have. 

    For Abdominal and Pelvis CT exams you will be instructed not to eat or drink anything for 4 hours beforehand. For all other CT’s there is no preparation. You may be asked to wear a gown for the CT exam.

  • What to expect at your appointment?

    During the Exam

    For your CT examination you will be asked to lie on a table that moves on a track through the doughnut-shaped scanner. As the procedure begins, you will hear humming, buzzing or clicking sounds from the CT machine. The table will move in and out of the scanner as the CT tube rotates around you. Each time you move in and out of the scanner, the scanner completes a separate view. The information is processed by the computer and displayed as images on a computer screen to the Technologist. You should remain as still as possible to produce the clearest images. Depending upon the procedure being performed, you may be asked to hold your breath for up to 30 seconds at a time for each series or set of images. Most exams require 15 to 30 minutes to complete. 

  • What is CT Contrast?

    A special dye called contrast material is needed for some CT scans to help highlight the areas of your body being examined. The contrast material blocks X-rays and appears white on images, which can help emphasize blood vessels, intestines or other structures.

  • Allergies

    Contrast Medium Intravenously

    If you are given contrast medium intravenously, you may notice a metallic taste in your mouth and a warm sensation throughout your body. These sensations are harmless and subside within a few moments.  Some patients may have an allergic reaction to the contrast medium, which is iodine-based. Patients who are allergic to iodine may experience itching, sneezing or other allergic symptoms in response. If you experience such a reaction you will be treated before being released to go home. In rare cases, the contrast medium can trigger anaphylaxis, a life-threatening allergic reaction in which the tissues of the airway become swollen enough to restrict breathing. In such rare, (only 1:100,000 patients have this type of reaction to CT contrast, emergency treatment is immediately given.

    Please let us know if you know or think you are allergic to iodine.

  • Patients Who Have Diabetes or Renal Disease

    Patients who have diabetes or renal disease require special care because the kidneys are involved in filtering iodine from the bloodstream. These patients should consult with their physician about proper scheduling of your CT scan, around your dialysis times. Our booking clerks will work with you to book your CT Scan with 24 hours of your next dialysis appointment, but you can wait to dialyse up to 48 hours post CT Contrast injection. 

    After your procedure, you will get a copy of your images and you and your physician will receive a copy of your report within 48 hours.
