About PET & CT Imaging
Cancer Screening in British Columbia
From; The Use of Positron Emission Tomography (PET) for Cancer Care Across Canada
Time for a National Strategy, 2011;
“Europe currently has 479 PET installations and that number is expected to grow to 742 by 2013 (MEDEC, 2010). The United States has approximately 2,000 PET scanners and a ratio of about 6.5 scanners per million (Buck et al., 2010). In comparison, Canada currently has 29 PET scanners and a ratio of 0.86 scanners per million people.
A large Canadian study by Worsley et al. (2010) evaluated the impact of PET on treatment changes and decision-making in 3,779 consecutive patients at the British Columbia Cancer Agency in Vancouver, British Columbia. Based on a standard physician’s questionnaire, it was found that the information derived from PET imaging resulted in a change in an individual patient’s treatment plan in 50% of cases and physicians reported an improved decision-making ability in 83% of cases”.
Greater Seattle has 14 scanners with a population of 3.1 million or 1 scanner per 221,000 people where prices average over $5,000 US per scan.
British Columbia Ministry of Health has 2 scanners in Vancouver for a population of 4.6 million people, or 1 scanner per 2.3 million.
Including Premier Diagnostic Center, there is 1 scanner per 1.536 million people in British Columbia, far below other developed countries.
Positron Emission Tomography (PET) & Computerized Tomography (CT)
Positron Emission Tomography (PET) and Computerized Tomography (CT) are state-of-the-art imaging tools that combine to pinpoint the location of active cancer within the body. “The highly sensitive PET scan images the biology of disorders at the molecular level revealing metastatic disease that other imaging techniques simply can’t detect.”
Meanwhile, the CT scan provides a detailed picture of the body’s internal anatomy. The PET/CT scan combines these two well-established imaging modalities into a single scan.
A tumor evident with CT scan can be confirmed as either malignant or benign with PET scan. PET/CT imaging has significant advantages for establishing treatment options and helping patients avoid multiple diagnostic procedures.
Premier Diagnostic Center is Western Canada’s only private PET/CT scan facility. We have more than 10 years of experience providing this more effective form of cancer screening. By taking advantage of our Vancouver PET/CT scan services, you can speed up the process of receiving a diagnosis and treatment.
Understanding How PET/CT Scans Work
A PET scan is very different from an ultrasound, X-ray, MRI, or CT scan. A PET scan allows the physician to distinguish between living and dead tissue, or between benign and malignant disorders. Since a PET scan images the biology of disorders, it can help the physician detect abnormalities in cellular activity at a very early stage, generally before anatomic changes are visible.
A CT scan is able to detect and localize changes in the body structure or anatomy, such as the size, shape, and exact location of an abnormal growth, a sizeable tumor, or a musculoskeletal injury.
PET/CT-fused coronal images demonstrate multiple areas of high Standardized Uptake Value FDG uptake in the liver that correspond to low attenuation lesions seen on the transmission CT scan. These lesions were compatible with metastasis (arrow).
