In this week’s #ChemSci pick, researchers have developed a molecular complex that could lead to high-quality MRI scans with lower toxicity than current methods.
Magnetic Resonance Imaging, or MRI, is a common medical diagnostic technique used for the non-invasive imaging of internal organs. To improve the brightness and clarity of an MRI scan, substances called contrast agents are used.
Most modern contrast agents contain the heavy metal gadolinium, which has proven to be toxic to some humans and the environment. Non-toxic alternatives are less effective because they degrade in the body and provide weaker contrast effects.
Now, in our Chemical Science Pick of the Week, researchers have developed a non-toxic molecular complex that overcomes these issues.
