Radioimmunodetection (RID) is a diagnostic technique that combines the principles of radioimmunology and imaging to identify and localize specific antigens in tissues or cells using radiolabeled antibodies. This method is primarily used in the field of oncology to detect cancerous tissues based on the presence of specific tumor markers or antigens. In RID, antibodies that are specific to the target antigen are labeled with a radioactive isotope.
