CT and PET/CT
Computerized Tomography (CT)
Computerized Tomography (CT) utilizes a rotating x-ray source, x-ray detectors, and a complex computer system to create cross sectional images of the body. CT was the first modality that allowed for the non-invasive visualization of internal structures and today remains the most widely used cross-sectional technology for brain and body imaging. We strive to be a leader in the reduction of radiation doses. Our staff acts as a resource to many outside institutions, and we are constantly making adjustments to our CT protocols to maintain the lowest dose possible without compromising image quality.

In December 2006, a 16-slice PET/CT scanner was installed at HSC and we now have the ability to produce incredibly detailed images that help precisely pin point the location of cancer within the body. This is a valuable tool that helps our physicians make necessary treatment recommendations and/or alterations to their existing treatment plans.
PET/CT is the basic fusion of two state of the art technologies. While the PET portion allows us to detect the metabolic signal of actively growing cancer cells, by monitoring glucose metabolism. The CT portion provides detailed anatomical information about the location, size, and shape of various lesions, but cannot differentiate cancerous lesions from normal structures with the same precision as PET.
As you can see, each technology on its own has distinct benefits and limitations, but once combined the collective images provide a comprehensive answer for our referring physicians. Every PET/CT scan at SickKids is reviewed and correlated by both a Nuclear Medicine Physician and a Radiologist during a unified review session. This collaboration has not only fused technologies but also departments. The PET/CT team is made up of two Nuclear Medicine Technologist and two CT Technologist that work together closely on a daily basis to ensure that the patient is receiving the best care possible.
