scintigraphic imaging of a lesion using radiolabeled monoclonal antibodies or antibody fragments specific for antigen that is associated with the lesion.
immunoscintigraphy/im·mu·no·scin·tig·raphy/ (-sin-tig´rah-fe) scintigraphic imaging of a lesion using radiolabeled monoclonal antibodies or antibody fragments specific for antigen associated with the lesion.
immunoscintigraphyImaging A procedure in which radioactively-labeled substances are administered and images obtained from body sites where the antibody localizes; the scintigraphic imaging of a CA after administrating a γ-emitting monoclonal antibody directed against a particular tumor-specific antigen
The imaging of specific tissues by means of their binding to radioactively labeled monoclonal antibodies; used to detect metastatic cancer. The release of radiation from the antibodies is detected and quantified.Synonym: radioimmunoimaging
