16-member Ring Matel Chelate
- Summary
- Metal chelates are useful for improving the contrast of X-ray, ultrasound, radionuclide and magnetic resonance (MR) images. However, the metal complexes must be stable and inert so that toxicity resulting from dissociation in the body can be minimized. This invention provides 16-member ring metal chelates that can provide a charge balanced metal complex having improved stability, especially for gadolinium(III) and samarium (III).
