Gadolinium is most mentioned in science and medicine, not common conversation.

Scientific Use

In MRIs, gadolinium helps to improve the visibility of internal structures.

MRI Enhancement

You'll rarely use 'gadolinium' unless dealing with specific fields like radiology.

Rare Mention

 I won't go into this very much, but our technology, besides being able to tag tumor and metastatic lymph nodes with fluorescence, we can also use the same smart three-part molecule to tag gadolinium onto the system so you can do this noninvasively.
