MR imaging of the liver using gadolinium chelates.

The use of gadolinium chelates has become an essential element in the comprehensive MR examination of the liver. The versatility of the gadolinium chelates, their well-established record of safety, and the wealth of clinical experience with these agents are unmatched. The gadolinium chelates uniquely provide important information about tumor perfusion, which is key in assessment of liver masses. These paramagnetic contrast agents assist with liver lesion detection, characterization, and in establishing the volume of viable perfused tumor.
