A F18 bone scan is a nuclear imaging test used to help diagnose problems with bones. It safely uses a very small amount of radioactive drug called a radiopharmaceutical. This scan is done in case of unexplained skeletal pain, bone infection, spread of tumour to bones or any bone injury that can't be seen on a standard X-ray.
This procedure does not require fasting or any diet restriction.
You must inform the doctor of any history of contrast allergy, asthma, arthritis, joint issues or fracture. In such cases, 15 minutes before the procedure, pre-medication is administered.
You must inform the doctor of any past history of surgery as well.
In case you have done this scan earlier, please carry your past reports / CDs.
If you know or think you could be pregnant, inform attending staff.
You must have plenty of water to flush out the radioactive medicine from the body.
You are settled comfortably in an area where your privacy is respected throughout the procedure. You will be given a hospital gown to change into.
You will have to take off all ornaments, metallic accessories and inner wear with metal wires etc.
In case of paediatrics or patients who do not cooperate, sedation is suggested.
A cannula is inserted and a small dose of radioactive injection is given via IV. You will then be isolated for 45 mins to 1 hour,
You must drink water during this isolation period, mineral water will be provided to you. Before you are taken for the imaging, you will be asked to void urine.
Post these isolation procedures, the whole body scan is done. The initial part of the scan is a diagnostic CT.
Post this PET imaging is done which usually takes about 10 to 15 mins.
Both CT scan and PET imaging are done in the same couch.
You must drink at least 2 to 3 litres of water during the course of the day, which is essential to flush out the remaining radioactive medicine in the body.
You must stay away from pregnant women and children for 24 hours, to avoid radioactive exposure.
Lactating mothers should stop feeding for 24 hours post-procedure.
There are no dietary restrictions post the procedure and you may resume all normal activities too.
Reports will be issued the next day.
