👉 Gadolinium is a chemical element that is used in the production of MRI (Magnetic Resonance Imaging) technology. It is also known as 18F-Gd, which stands for gadolinium-99 molybdate. Gadolinium is an essential component in MRI machines and has been used since the 1960s to enhance the image quality of the brain by increasing signal-to-noise ratio (SNR).
