An injectable contrast agent for magnetic resonance imaging that coalesces into a solid now enables long-term monitoring of oxygen levels in tissues without the need for an invasive procedure, which is required to implant standard oxygen electrodes or a solid MRI contrast agent (Proc. Natl. Acad. Sci. USA 2014, DOI: 10.1073/pnas.1400015111). The new material maintains the concentration of the contrast agent in the . . .
