Abstract: A method for establishing a local concentration distribution of magnetic particles of at least one particle class within an examination volume or a variable derived from this concentration distribution. The method includes providing at least one system matrix, providing MPI signal data of at least one sample including magnetic particles of at least one particle class within a measurement volume, and reconstructing spatially resolved MPI image data from the provided MPI signal data. At least one spatial projection of at least one part of the system matrix is carried out along a projection direction and a projected system matrix is generated thereby. The reconstruction of the MPI image data is implemented with the at least partly projected system matrix, as a result of which MPI image data of a spatial projection of the local concentration distribution of the magnetic particles are produced along the projection direction.

Abstract: The invention relates to compounds known as “optorelaxers,” for example, spin crossover (SCO) complexes that exhibit light-induced excited state spin trapping (LIESST) effects with transient unpaired electron spins, which are created (or destroyed) by varying the level and/or wavelength of light to which the complexes are exposed. Light conditions are used to switch the optorelaxers between transient paramagnetic and diamagnetic states to provide real-time control of T1 relaxation in nuclear magnetic resonance (NMR) spectroscopy methods. The optorelaxers and methods of the invention provide increased detection sensitivity of NMR spectroscopy, with increased structural information content, while maintaining resolution for a wide variety of different NMR-active nuclei.
