11C-Trimethoprim PET/CT Imaging to Evaluate Biodistribution and Kinetics in Human Subjects

\[11C\]TMP is a radiolabeled imaging agent for positron emission tomography (PET/CT). Most relevant to this protocol, it is for imaging bacterial infection in human subjects. TMP is well-known, safe, broad-spectrum, synthetic, small molecule antibiotic that has been used clinically for over 50 years for the treatment of acute bacterial infection and has been combined with sulfa-based antibiotics (Bactrim/Septra) for bacterial infection prophylaxis especially in the lung and bladder.
