Radiolabeled autologous leukocyte (None (the process is sometimes abbreviated as "WBC scan," "In-111 leukocyte scan," or "99mTc-HMPAO leukocyte scan," but these are not abbreviations of a molecular target))

Radiolabeled autologous leukocytes are a diagnostic agent made by isolating white blood cells from a patient's own blood, labeling them ex vivo with a radioactive compound (usually indium-111 or technetium-99m), and re-injecting them for imaging. After injection, these cells migrate to sites of active infection or inflammation, allowing visualization of these regions by nuclear medicine techniques such as gamma camera scintigraphy. This approach is considered the gold standard for infection imaging but is not a molecular therapy target. The procedure is regulatory-intensive, labor-intensive, and carries risks such as patient/operator exposure, but provides highly specific localization of inflammatory processes within the body
