What does the machine look like?
It is a large machine, open at both ends, and very similar to a CT scanner. (Click on the “scanner” on our technology page to get a 360 view)
What is FDG?
FDG, or Fluorodeoxyglucose, is a glucose analog, or chemical, that’s injected into a patient and then read by the PET scanner. The PET scanner uses the FDG to form images that can then be interpreted by a radiologist. Our new generation GE Discovery IQ System allows us to use less FDG, thereby reducing radiation exposure.
Does the FDG injection I receive contain a dye or other substance I may be allergic to?
No, there are no documented side effects to FDG which contains glucose (something your body manufactures naturally) along with a radiopharmaceutical.
Am I allowed to eat and take my medications?
For non-diabetic patients the general instructions are to eat nothing 5 hours prior to your appointment time. You may, however, drink water and take all your medications (unless they are restricted by a full stomach or are prescribed with food).
We ask that diabetic patients contact our office 24 hours prior to their exam for specific instructions.
Someone from our offices will call the day before your appointment to review all of the instructions and requirements with you. If you have any questions do not hesitate to contact us.
What should I wear?
We ask that you wear loose, warm comfortable clothes, with no metal buttons, zippers etc. Please leave all jewelry and valuables at home.
What does PET/CT stand for?
Positron Emission Tomography/Computed Tomography
