A PET (positron emission tomography) scan combined with a CT scan is a specialised imaging test. It may take several hours to prepare for and complete a PET–CT scan. Before the scan you will be injected with a small amount of radioactive material to highlight tumours in the body.
The radioactive material may be either:
68-Gallium DOTATATE (GaTate)
For most pancreatic NETs, the radioactive material used in a PET scan is 68-Gallium DOTATATE. This scan can help show the exact position of pancreatic NETS and may show tumours that don’t appear on other scans. It may also be used to help work out whether a pancreatic NET has spread. For some pancreatic NETs, an FDG-PET is used instead of or as well as this test.
Fluorodeoxyglucose (FDG)
This substance is commonly used in PET scans. Some cancer cells may show up brighter on the scan because they take up more glucose solution than normal cells do. This scan can help doctors work out whether pancreatic NETs has spread or how it is responding to treatment.
| These specialised PET scans are not available in every hospital and may not be covered by Medicare, so talk to your medical team for more information. |
