One out of every four Canadians will die from cancer.Let that sink in.

Cancer is the leading cause of premature death in Canadians, and the number of cases will increase each year as the population grows and ages. Positron emission tomography (PET) is a medical imaging technique that is used to visualize metabolic processes in the body. When properly implemented PET is both a clinically- and cost-effective diagnostic modality for cancer, and has a significant influence on the management strategies of patients. PET is the world standard for cancer imaging and management. Canada lags behind virtually every developed nation in the world in its adoption of PET and other diagnostic technologies and the province of Ontario in particular has restricted patient access to PET for the last 15 years.

The time to expand PET use in Ontario is now.

Questionable policies and conduct at all levels of government have derailed cancer care.

Unethical Practices

PET clinical trials have been accused of violating fundamental research ethics by using imaging and data analysis techniques incapable of detecting potential metastatic disease and thus unsuitable for the purposes of the trials. This exemplifies measures taken by the province to delay PET access for Ontario cancer patients.

Hidden Agendas

The Ministry of Health has been accused of deliberately structuring clinical research protocols that would present PET in a negative light to further delay its introduction to Ontario cancer patients. Meanwhile PET imaging had already been approved in the United States and United Kingdom for multiple forms of cancer.

Patient Safety

Ontario's illogical PET guidelines expose lung cancer patients to high risk chest needle biopsies before they can be even considered a candidate for a PET scan. This potentially harmful procedure can result in collapsed lungs or bleeding that can lead to hospitalization and immediate surgery to control bleeding.

How does PET work?

Positron emission tomography (PET) is a non-invasive medical imaging technique that is used to observe metabolic processes in the body.

Diagnostic role in Cancer

PET is widely used in clinical oncology. Cancer cells exhibit high metabolic activity and can be easily imaged by their uptake of tracer molecules.

PET use in Canada

PET is unevenly deployed across Canada; the availability and utilization of PET infrastructure varies considerably, province by province.
