IMAGING: PET/CT

Sodium Fluoride (NaF18) Bone Scan

What: An NaF PET/CT Bone Scan is used to detect areas of bone abnormality due to fracture, tumors or other bone diseases. Most often, this exam is used for oncologic applications.

An image is taken of the entire skeletal system determining if cancer or other disease has spread to any bones in the body. This allows appropriate treatment to begin as soon as possible.

What to expect: Plan to be at the testing center for 2 to 2 ½ hours. It is important to arrive on time. If you cannot arrive on time, please call 24 hours in advance to reschedule your test.

The technologist will start an IV and inject a small amount of sodium fluoride. The IV will be removed and you will be asked to relax quietly in a comfortable recliner while the sodium fluoride works its way through your body. You may read or use electronic devices during the uptake period for a sodium fluoride bone scan.After the resting period you will be asked to empty your bladder and the technologist will escort you into the scanning room where you will lie down on the scanner table. It is important that you are comfortable and will need to lie as still as possible for 25-35 minutes as the table passes slowly through the scanner acquiring several sets of images. The procedure is painless and has no side effects.

Prep: The prep for the bone scan is different than a general PET/CT. You may continue to eat and drink normally prior to and after the scan. If you are on any medications, you may continue to take them. Drink plenty of fluids before and after the exam.

Safety notes: Follow the same safety guidelines as the general PET/CT.
