MRIkontrastmittel
MRI contrast agents, also known as MRI contrast media or MRI contrast enhancers, are substances administered to patients undergoing magnetic resonance imaging (MRI) scans to improve the visibility of specific tissues or lesions. These agents work by altering the magnetic properties of nearby water molecules, thereby changing the signal intensity on the MRI images. This contrast enhancement can help radiologists distinguish between normal and abnormal tissues, such as tumors or areas of inflammation, and better define anatomical structures.
The most commonly used MRI contrast agents are based on gadolinium, a paramagnetic metal. When gadolinium is
Before administering an MRI contrast agent, a healthcare professional will assess the patient's medical history, particularly
