What does enhancement on MRI mean?

Gadolinium is a chemical compound given during MRI scans that highlights areas of inflammation (Active Lesions). A gadolinium-enhanced MRI scan shows active lesions, meaning that there is a breakdown of the blood-brain barrier and inflammation is present. Therefore, gadolinium-enhanced lesions are new.

Which is better for abdomen CT scan or MRI?

Both MRIs and CT scans can view internal body structures. However, a CT scan is faster and can provide pictures of tissues, organs, and skeletal structure. An MRI is highly adept at capturing images that help doctors determine if there are abnormal tissues within the body.
