"Talc deposits produce areas of increased 18F-FDG uptake. If the area of high attenuation corresponds with the FDG-avid lesion, it is highly suggestive of talc deposition 9. Talc is hydrated magnesium silicate and is not metabolised by the body 10. The body mounts an inflammatory, granulomatous response - macrophages and giant cells remain chronically activated around talc particles. This subsequently drives an ongoing glucose metabolism, which results in persistent FDG avidity that has been proven to last at least 50 years in certain individuals 3,11."
"The typical SUV range for talc pleurodesis is 2.1 - 9.4 12."
