123I-MIBG scintigraphy

123I-MIBG scintigraphy is an imaging test that uses a special radioactive substance called MIBG, labeled with iodine-123, to visualize certain nerve and tumor cells in the body. After injection, the substance is absorbed mainly by nerve tissues and tumors like neuroendocrine tumors or certain types of adrenal gland tumors. A special camera detects the radiation emitted by the MIBG, creating detailed images that help doctors locate or assess these tumors. This test is useful for diagnosing, staging, and planning treatment for specific tumors involving nerve tissue or the adrenal glands.
