Before and after the PET-CT
Before the PET-CT
There is very little preparation needed for a PET-CT scan for most patients.
However, if you are diabetic or take any special medication, eg. Chemotherapy or steroids, you should inform our friendly staff at the time of making your booking as special precautions and preparation are necessary.
You will typically be asked to fast for 6 hours prior to the examination, although water and any medications that can be tolerated on an empty stomach is allowed.
No strenuous exercise is to be performed during the 24 hours prior to your appointment.
On the day of your procedure, an injection of the radioactive sugar is administered and you will be asked to lie down on a bed or to sit in a chair for 60-90 minutes while the sugar travels through the body.
After the PET-CT
Digital images and reports will available to your referring doctor once our expert radiologists and nuclear medicine physicians have completed their combined diagnosis.
The patient may resume normal daily activity. The radioactively labelled substance, FDG will leave your body fairly rapidly. Consuming lots of water after the scan will help this process.
