The present invention relates to an arrangement and a method for providing contrast agent for e.g. MRI (Magnetic Resonance Imaging) and NMR (Nuclear Magnetic Resonance) applications. The method according to the invention comprises the steps of obtaining (100) a solution in a solvent of a hydrogenatable, unsaturated substrate compound and a catalyst for the hydrogenation of a substrate compound, hydrogenating (110) the substrate with hydrogen gas (H2) enriched in para-hydrogen (p-1H2) to form a hydrogenated contrast agent and exposing (120, 305) the contrast agent to a sequence of pulses of magnetic field. The apparatus comprises a magnetic treatment unit (240) equipped with means for producing pulses of magnetic field.
