Questions

  1. Are there any non-ionic iodinated contrast agents, such as Iopamiron?

    1 answer
    1. iopamiron is not available but iodixanol, iopromide, and iohexol can be used as reference standards, which are likely more expensive on a per gram basis due to their intended use. The only other chemical close to iopamiron is ionic rather than non-ionic.
