Computed tomography, (CT) also known as a CT or CAT scan, is an imaging procedure that uses special X-ray equipment to create detailed pictures of areas inside the body. Unlike a typical X-ray, multiple images, also known as slices, are taken. The images then appear almost like the slices in a loaf of bread.
An X-ray technologist, who has special training in CT Scanning, will perform your scan and the images are then read by a radiologist, who is a doctor with special training in computed tomography. The technologists operating the CT scanners are registered with the College of Medical Radiation Technologists of Ontario.
A CT scan can be done on the following areas of the body:
- Head/brain
- Neck
- Spine
- Chest
- Abdomen - liver, kidneys, spleen, pancreas, stomach and bowels
- Pelvis - ovaries, prostate, bladder
- Upper limbs - shoulders, elbows, wrists and hands
- Lower limb - hips, knees, feet and ankles
- Lung (for CT Lung Biopsies read the Patient Pamphlet here)
- Heart
- Veins and arteries
- 3-D reconstructions of body parts or tissues
