Gadoterate Meglumine
Mechanism :
Its a paramagnetic agent, used to detect lesion detection during MRI, a causes increased signal intensity by developing a magenetic moment when placed in magnetic field thereby shortening T1 and T2 in target tissues. When administered the effects are primarily observed in the T1 relaxation time.
