(darkening contrast) MRI agent, a more biocompatible, robust methodology is required to use it as a T1-weighted agent (brightening contrast) to diagnose vascular disease. We hypothesized that the induced magnetic moment of Mn12 clusters in the applied field would accelerate the relaxation of surrounding water protons. Clearly, a more biocompatible approach is the unmet need by restricting the agent within a size range of
