18F-FDG PET Uptake in the Scalp After Platelet-Rich Plasma Therapy

The document reported a case involving a 43-year-old woman with a history of right breast cancer who showed increased FDG avidity in the scalp following platelet-rich plasma therapy, as observed through 18F-FDG PET/CT imaging. This imaging technique was noted for its utility in detecting sources of infection or inflammation in the body. The findings were incidental, suggesting that platelet-rich plasma therapy, a treatment aimed at promoting hair regrowth by injecting plasma into the scalp, might influence FDG uptake in the scalp.
