Two types of contrast media are now used in clinical magnetic resonance imaging (MRI). Intravenous gadolinium-DTPA serves as a marker of blood-brain barrier disruption while intravenous magnetic iron oxide particles are of value in imaging the liver and spleen. The efficacy of MRI is improved with these agents but the examination is prolonged.
目前，临床磁共振成像（MRI）中使用两种造影剂。静脉注射钆-二乙三胺五乙酸（gadolinium-DTPA）可作为血脑屏障破坏的标志物，而静脉注射磁性氧化铁颗粒对肝脏和脾脏成像有价值。使用这些造影剂可提高MRI的效能，但检查时间会延长。
