Is this trial a fit for you?

Likely a good fit

Healthy volunteers aged over 50 without metabolic or metastatic bone disease, with suitable venous access and ability to stay still for 60 minutes.

Probably not a fit

Individuals with metal implants, claustrophobia, pregnancy, uncontrolled hypertension, or body size outside specified limits may not benefit from or qualify for this imaging approach.

What this trial studies

This is a prospective, single-center, exploratory pilot study conducted at King's College London. Ten healthy volunteers (5 men and 5 women, all over 50) will undergo a 1-hour dynamic total-body PET/CT scan after a bolus injection of 90 MBq of [18F]-sodium fluoride to measure bone perfusion (K1) and regional bone plasma clearance (Ki). Five blood samples will accompany the scan to verify arterial input function and adjust measurements for plasma concentration. The study uses the latest high-sensitivity total-body PET/CT technology to improve accuracy of bone perfusion assessment compared with older scanners.

Why it matters

Potential benefit: If successful, this approach could provide a more accurate and convenient way to measure bone blood flow in clinical research and potentially aid in understanding bone diseases.

How similar studies have gone: Previous animal studies and early human imaging using [18F]-NaF with PET suggested potential for measuring bone perfusion, and newer total-body PET/CT systems may improve accuracy.
