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 MediaArticlesSeeing color though a dog’s eyesGrowing up, most people were probably told that dogs cannot see the world in quite the same way that the average human can — perceiving the world in black and white and shades of gray instead...BioPhotonics May/Jun 2024 IssueQuantum Optical Sensor Aims to Increase MRI Scan Quality, SpeedAlthough MRI scanners provide 3D images of exceptional quality, the strong magnetic fields used to create these images have fluctuations that can introduce errors and disturbances in scans....Photonics Spectra August 2024 IssueOnline or In-Person: How Do We Connect and Engage?Most of what we know about how the human brain functions is based on studies of brain activity in single individuals under very controlled parameters.
