Oral manganese for liver imaging at three different field strengths.

Rationale And Objectives: To study the magnetic resonance imaging signal intensity of the liver and gall bladder before and after ingestion of a new oral manganese containing contrast medium at three different field strengths.

Materials And Methods: Twelve healthy male volunteers (mean age, 24.9 years; range, 20-39 years) underwent abdominal magnetic resonance imaging (T(2)W COR, T(1)W COR, T(1)W TRA) at 0.
