Mangafodipir
From Wikipedia, the free encyclopedia
Mangafodipir (sold under the brand name Teslascan as mangafodipir trisodium) is a contrast agent delivered intravenously to enhance contrast in magnetic resonance imaging (MRI) of the liver. It has two parts, paramagnetic manganese (II) ions and the chelating agent fodipir (dipyridoxyl diphosphate). Normal liver tissue absorbs the manganese more than abnormal or cancerous tissue. The manganese shortens the longitudinal relaxation time (T1), making the normal tissue appear brighter in MRIs. This enhanced contrast allows lesions to be more easily identified.
