About PET

PET stands for Positron Emission Tomography.

The patient receives an intravenous injection of radioactive glucose (18F-FDG).
The cancer cells are usually highly metabolic and consume about 3-8 times more glucose than normal cells.
PET can thus be used to detect cancer cells.


PET Procedures

1 . Before PET

Pre-procedural fasting for 4-6 hours before the procedure, except water.

2 . Injection

Radioactive glucose (18F-FDG) will be injected.

3 . Rest

Lie down until the injection can spread throughout the body (about 1 hour).

4 . Examination

Remain still while images are recorded (20-30 minutes).
