In short
Sodium Fluoride (18F) is a radioactive tracer used in medical imaging, particularly in PET/CT scans. This article explores its application in clinical trials for various conditions, including fibrous dysplasia/McCune-Albright syndrome and transthyretin amyloid cardiomyopathy. We'll discuss how this tracer is being used to enhance diagnostic capabilities and monitor treatment effectiveness in these studies.

What is SODIUM FLUORIDE (18F)?
SODIUM FLUORIDE (18F), also known as Radio-Flu or Sodium Fluoride F-18, is a radioactive substance used in medical imaging. It's not a medication that treats diseases directly, but rather a diagnostic tool that helps doctors see what's happening inside your body.
Medical Uses
SODIUM FLUORIDE (18F) is primarily used in a type of medical imaging called PET/CT (Positron Emission Tomography/Computed Tomography). This imaging technique is helpful in several medical conditions:
- Bone disorders: It's being studied in patients with a condition called Fibrous Dysplasia/McCune-Albright Syndrome, a disorder that affects bone development.
- Heart conditions: Researchers are investigating its use in patients with Transthyretin Amyloid Cardiomyopathy, a heart condition where abnormal proteins build up in the heart.
In these conditions, SODIUM FLUORIDE (18F) can help doctors:
- Measure the activity of bone lesions (abnormal areas of bone)
- Quantify microcalcification (tiny deposits of calcium) in the heart muscle
- Monitor how diseases progress over time
- Evaluate how well treatments are working
How is it Administered?
SODIUM FLUORIDE (18F) is given as an intravenous injection. This means it's injected directly into a vein, usually in your arm. After the injection, you'll undergo a PET/CT scan, which combines two types of imaging to create detailed pictures of your body.
Dosage Information
The dosage of SODIUM FLUORIDE (18F) can vary depending on the specific use and the patient's characteristics. However, based on the available information:
- The maximum daily dose is typically around 370 MBq/kg (megabecquerels per kilogram of body weight)
- In some studies, a dose of 2 MBq/kg is used
It's important to note that the exact dose will be determined by your healthcare provider based on your individual needs and the specific imaging requirements.
Current Clinical Trials
SODIUM FLUORIDE (18F) is currently being studied in several clinical trials:
- DEnosumab for the treatment of FIbrous Dysplasia/McCune-Albright Syndrome in adults (DeFiD): This study is using SODIUM FLUORIDE (18F) PET/CT to evaluate the activity of bone lesions in patients with Fibrous Dysplasia/McCune-Albright Syndrome. The imaging will help assess how well a drug called Denosumab works in treating this condition.
- i-Care; Quantitative-imaging in cardiac transthyretin amyloidosis: This study is using SODIUM FLUORIDE (18F) PET/CT to measure microcalcification in the heart muscle of patients with Transthyretin Amyloid Cardiomyopathy. The goal is to better understand and monitor this heart condition.
Safety Considerations
While SODIUM FLUORIDE (18F) is generally considered safe for diagnostic use, there are some important considerations:
- It should not be used in pregnant or breastfeeding women.
- It may not be suitable for people with severe kidney problems (with an estimated glomerular filtration rate less than 30 mL/min/1.73m2).
- As with any radioactive substance, its use is carefully controlled to minimize radiation exposure.
Always inform your healthcare provider about all your medical conditions and any medications you're taking before undergoing any procedure involving SODIUM FLUORIDE (18F).
