Opinion: Pet scans effective but underused

October 5, 2012

Saskatoon will soon become home to Saskatchewan's first PET scanner. This is a significant development for cancer patients, as PET (positron emission tomography) is the most powerful diagnostic tool for detecting cancer and optimizing cancer management.

PET has the unique capability to detect active cancer cells before they become a mass that can be identified by computerized tomography (CT) or magnetic resonance imaging (MRI). Consequently, PET detects cancer much earlier when used in the initial diagnosis, searching for recurrence or monitoring the success/failure of cancer therapies.
