1. What Gadovist is and what it is used for

Gadovist is a contrast enhancer used for diagnostic magnetic resonance imaging (MRI) of the brain, spine, and blood vessels. Gadovist may also make it easier for the doctor to check if known or suspected changes in the liver and kidneys are benign or malignant.
Gadovist can also be used in MRI of abnormalities in other body regions. Gadovist makes it easier to see abnormal structures and changes and makes it easier to distinguish between healthy and diseased tissue. It is used for adults and children of all ages.

How Gadovist works

MRI is a form of medical imaging technology based on the behavior of water molecules in normal and abnormal tissue. The technology is based on an intricate system of magnets and radio waves. Computers record the activity and transfer it to visible images.

Gadovist is given as an injection in a friend. This medicine is for diagnostic purposes only and will only be given by healthcare professionals with experience in clinical MRI.
