"A substance being studied as a way to find sentinel lymph nodes in some types of skin cancer and breast cancer. It contains a radioactive substance called technetium linked to a substance called dextran. Dextran helps technetium stay in blood and lymph vessels after it is injected. A machine or probe that detects radioactivity shows which lymph nodes near the tumor have technetium Tc 99m dextran in them. It is a type of radiopharmaceutical and a type of radioimaging agent.NCI-GLOSS" . "42776"^^ . "Technetium 99m DextranSYNCI" . "Technetium Tc-99m Dextran"^^ . "42776"^^ . . "Tc_99m_Dextran"^^ .
