Virkningen af mangafodipir er at afkorte den longitudinale relaxationstid (T1) af target væv under MRI, hvilket bevirker en øgning i signalintensitet (klarhed) af, f. eks. pancreas og lever parenkym.
The effect of mangafodipir is to shorten the longitudinal relaxation time (T1) of targeted tissues during MRI, leading to an increase in signal intensity (brightness) of, for example, pancreas and liver parenchyma.
