WebA) Iodine-131 can be detected by an MRI. Concentration in the thyroid at abnormally high concentrations would indicate a thyroid problem. B) Given at lose doses, iodine-131 can be used as a chemotherapeutic towards thyroid cancers. It'll get concentrated in cancerous cells and beta-emission will inevitably destroy the cell. Iodine-131 is used for unsealed source radiotherapy in nuclear medicine to treat several conditions. It can also be detected by gamma cameras for diagnostic imaging, however it is rarely administered for diagnostic purposes only, imaging will normally be done following a therapeutic dose.
