Positron Emission Tomography - PET-CT Scan
Indications and Procedures
- Indication: Most commonly used to detect:Cancer, heart problems, brain disorders PET scans are useful both for detecting cancer and for:
- diagnosing if the cancer has spread
- observing if a cancer treatment is working
- checking for a cancer recurrence
- Procedures: A small intravenous catheter will be inserted into a vein in the arm. This is done in a separate quiet room while the radioactive tracer is injected. The tracer fluorine 18-fluorodeoxyglucose (FDG), the FDG is allowed to circulate throughout your body during a 45-minute uptake period. The patient is then placed on a table in the PET-CT scanner, detectors are then used to locate areas of increased accumulation of the tracer compared to the normal tissue.
