CT (Computer Tomography)

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. 

The first CT scanner was installed at Kingston General Hospital back in the fall of 1977 and since then, the technology has grown quickly. KGH has continued to upgrade and replace our CT equipment to keep pace with the ever improving technology.  Presently the department has two CT scanners; The General Electric Brightspeed (16 Slice) and the General Electric VCT (64slice).

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
  • Heart
  • Veins and arteries
  • 3-D reconstructions of body parts or tissues
