Main Methods:

  • Literature review of current gastrointestinal contrast agents for MR imaging.
  • Classification and comparative analysis of major enteric MR agents.
  • Discussion of the future outlook for these agents.

Main Results:

  • Several enteric MR agents are under development, each with unique properties.
  • Key differences in efficacy, safety, and imaging characteristics exist among agents.
  • The need for improved agents with specific characteristics is highlighted.

Conclusions:

  • Gastrointestinal contrast agents are crucial for advancing MR imaging of the digestive system.
  • Ongoing research aims to optimize agent properties for enhanced diagnostic capabilities.
  • Future developments will likely focus on targeted delivery and improved safety profiles.
