BALTIMORE, May 1 -- In what is believed to be a first-of-its-kind study, Johns Hopkins University researchers have used magnetic resonance imaging (MRI) to measure sodium concentrations in the cells of malignant brain tumors. Because growth of such cancers are linked to elevated sodium levels, an easy way to measure them could improve diagnosis and treatment monitoring. The study is published in the today's edition of Radiology. "Determining precise sodium concentrations has been a problem, but MRI can do it at the same time it identifies possible malignant lesions," said Ronald Ouwerkerk,...Read full articleRelated content from Photonics MediaArticlesOptical Fiber Sensors Enable New Biomedical DevicesThe biomedical community recognized the advantages of optical fibers long ago, accepting them even before their adoption for long-haul telecommunications1.
