- 1. Tc 99m
- [One of the radioactive isotopes of technetium, a gamma/beta-emitter with a half life of 6 hours. ( NCI )] (UMLS (NCI) C0303611) =Indicator, Reagent, or Diagnostic Aid; Element, Ion, or Isotope =Tc element;
| - 5. Tc 99m Monoclonal Antibody 170
- [A radioimmunoconjugate of a murine whole immunoglobulin G monoclonal antibody MAb-170 labeled with Technetium 99m (Tc-99m). MAb-170, originally raised against a carbohydrate epitope (a synthetic Thomsen-Friedenreich antigen), has been found to have panadenocarcinoma affinity, including adenocarcinomas of breast, fallopian tube, colon, endometrium, prostate, bladder, liver, lung, and ovary. Tc-99m MAb-170 delivers gamma emission Tc-99m nuclide directly to adenocarcinoma tissues, thereby may be used in diagnostic or imaging purpose. ( NCI )] (UMLS (NCI) C0393033) =Amino Acid, Peptide, or Protein; Pharmacologic Substance; Immunologic Factor

- 2. Tc 99m Dextran
- [A radiolabeled substance that is used in cancer diagnosis. ( NCI )] (UMLS (NCI) C0076028) =Carbohydrate; Indicator, Reagent, or Diagnostic Aid
| - 6. Tc 99m Sestamibi
- [Sestamibi is a large synthetic molecule of the isonitrile family, which can be labeled with Tc99m. It passes through cells membranes passively, collecting in cells with large numbers of mitochondria. It is often used for imaging of the thyroid and parathyroid. ( NCI )] (UMLS (NCI) C0162680) =Organic Chemical; Indicator, Reagent, or Diagnostic Aid

- 3. Tc 99m Human Serum Albumin Colloid
- [A colloid formulation of human serum albumin (HSA) labeled with Technetium-99m (Tc-99m) with diagnostic imaging properties. This HSA radioconjugate contains the gamma-emitting Tc99m, a metastable nuclide of molybdenum-99. A potential advantage of the Tc-99m-HSA suspension is its smaller colloid particle size compared to formulations containing either sulfur or tin, thereby allowing for enhanced imaging of the lymphatic draining pattern during lymphoscintigraphic or sentinel lymph node mapping procedures. ( NCI )] (UMLS (NCI) C0879625) Technetium Tc 99m Human Serum Albumin Colloid =Amino Acid, Peptide, or Protein; Pharmacologic Substance ;
| - 7. Tc 99m Sulfur Colloid
- [A gamma-emitting colloid used in scintillation scanning of the reticuloendothelial system (RES). After intravenous administration, technetium Tc 99m sulfur colloid is phagocytized by the reticuloendothelial system and concentrated in the liver, spleen, and bone marrow; detection/localization of phagocytized gamma ray-emitting colloid is performed with a gamma-ray scintillation camera. Scintillation scanning using technetium Tc 99m colloid sulfur helps determine the distribution and function of the RES and the extent to which tumor involves the RES. The RES includes cells types that can phagocytize and sequester inert particles and vital dyes; RES cell types include macrophages or macrophage precursors, specialized endothelial cells lining the sinusoids of the liver, spleen, and bone marrow, and reticular cells of lymphatic tissue and of bone marrow. ( NCI )] (UMLS (NCI) C0039419) =Indicator, Reagent, or Diagnostic Aid; Inorganic Chemical

- 4. Tc 99m LL2
- [A radioimmunoconjugate of the humanized IgG1 monoclonal antibody (MoAb) LL2 labeled with Technetium 99m (Tc-99m). Epratuzumab (MoAb LL2) recognizes CD22, a B-lymphocyte-restricted antigen expressed as a cytoplasmic protein in progenitor B cells, and as a cell surface protein in mature B cells. Tc-99m epratuzumab delivers gamma emission Tc-99m directly to B-lymphocyte lineage cells, thereby may be used in diagnosis or treatment purposes. ( NCI )] (UMLS (NCI) C0678085) =Amino Acid, Peptide, or Protein; Pharmacologic Substance; Immunologic Factor
