Gadoterate meglumine

Gadoterate meglumine (also known by the tradename Dotarem®) is an intravenous extracellular MRI contrast agent.

  • cyclic, ionic molecule 
  • 100% renally excreted
  • T1 relaxivity at 1.5 T: 3.4-3.8 L/mmol.S (slightly lower than other extracellular contrast agents)
  • concentration: 0.5 mmol/mL
  • recommended dosage: 0.1 mmol/kg

It is considered a high-stability agent, and is considered a good choice for patients with lower GFRs (see: nephrogenic systemic fibrosis)

It is also licensed in Europe and Australia for intra-articular use, when it is sold in prefilled syringes as Artirem®, which is chemically identical to Dotarem®.  It is not licensed for this use in North America.
