A method for preparing an NMR material, comprising generating parahydrogen in gas or liquid form at a first location; transporting the parahydrogen away from the first location; mixing a precursor compound including a metabolite component with a catalyst for hydrogenation; hydrogenating the precursor compound using the parahydrogen; transferring polarization in the precursor compound to a nuclear spin of the metabolite component; cleaving a side arm of the precursor compound in a chemical reaction, with the metabolite molecule being one of the products of the reaction; separating the metabolite molecule from the catalyst for hydrogenation and other products of the reaction; and generating metabolite molecules for use in an MRI scanner by extracting a sample of the metabolite molecule having at least 5% polarization.

Systems and method for generation of hyperpolarized materials

A method for generating a nuclear magnetic resonance spectrum of nuclear spin moments of a sample includes a static magnetic field permeating the sample, and a detection spin moment with a detection region surrounding the latter. The detection region extends at least partly into the sample. The method also includes an antenna element for radiating in frequency pulses for influencing the nuclear spin moments and radio-frequency pulses for influencing the detection spin moment, where a polarization step involves polarizing at least one portion of the nuclear spin moments along the magnetic field to form a longitudinal magnetization, where a transfer step involves converting the longitudinal magnetization (M) into a transverse magnetization (M) by radiating in a frequency pulse (F) with a 90&#xb0; flip angle, wherein a detection step involves radiating in a sequence of radio-frequency pulses onto the detection spin moment and subsequently detecting a signal (') of the transverse magnetization (M) present in the detection region and storing the signal as detection result in a list. The detection step is carried out a number of times repeatedly in succession, wherein the polarization step and the transfer step and also the detection steps are carried out.
