Over 200,000 new cancer cases are diagnosed in Canada each year. With imaging using an appropriate modality, many types of cancer that manifest as solid tumors can be detected, treated or managed effectively. Positron emission tomography (PET) combined with computed tomography (CT) is the primary imaging modality in a range of cancer types. Scientific studies have determined that measuring the size, shape, and texture of tumors from PET/CT images can help identify patients at high risk of early cancer recurrence, or for whom the standard treatment may fail.
