Radioimmunoscintigraphy (RIS) is an imaging modality that uses radiolabeled monoclonal antibodies to target specific tissue types. Monoclonal antibodies that react with specific cellular antigens are conjugated with a radiolabeled isotope. The labeled antibody-isotope conjugate is then injected into the individual and allowed to localize to the target over a 2 to 7 day period. The individual then undergoes imaging with a nuclear medicine gamma camera, and radioisotope counts are analyzed. Imaging can be performed with planar techniques or by using a single-photon emission computed tomography (SPECT). One example of a monoclonal antibody directed at extracellular prostate-specific membrane antigen is indium 111 capromab pendetide (ProstaScint®).
Radioimmunoscintigraphy imaging with indium-111 capromab pendetide for the diagnosis, treatment or management of prostate cancer is considered investigational.
