The team also includes a Medical Physicist, Pharmacist, Nuclear Medicine Technologist, Registered Staff Nurse and other administrative staff all trained in PET-CT services.

What is PET-CT?

PET (Positron Emission Tomography) is an advanced, cutting edge imaging modality in Nuclear Medicine. It is an imaging procedure showing the chemical function of an organ or tissue in addition to its structure, particularly cancer, using 18F Fluorodeoxyglucose (FDG). The CT or Computed Tomography component is built into this special scanner. Therefore, PET-CT is a fusion of two modalities; PET and CT scanner which provide functional and anatomical information simultaneously.

The combination of the two scans has been proven to be extremely sensitive for detecting the early stages of the disease and can detect abnormalities even in the absence of structural change. Small tumours may be found even if they are undetectable by other imaging procedures, which can be a major impact on choosing the best treatment options for patients.

Is PET-CT Scan safe?

Yes. The radiation received from the CT scan is low. For the PET scan, only a very small amount of F-18 FDG is injected and it loses radioactivity very quickly, with little or negligible radioactivity remaining in your body after 20 hours.
