Diffusion-Weighted Spectroscopy: A Novel Approach to Determine Macromolecule Resonances in Short-Echo Time H-1-MRS

Nicolas Kunz, Rolf Gruetter, Cristina Ramona Cudalbu

Quantification of short-echo time proton magnetic resonance spectroscopy results in >18 metabolite concentrations (neurochemical profile). Their quantification accuracy depends on the assessment of the contribution of macromolecule (MM) resonances, previou ...

Hyperpolarized Lithium-6 as a Sensor of Nanomolar Contrast Agents

Arnaud Comment, Jacques Van Der Klink, Chiara Perazzolo, Rolf Gruetter, Sami Jannin, Ruud van Heeswijk, Fiodar Kurdzesau, Cristina Ramona Cudalbu

Lithium is widely used in psychotherapy. The Li-6 isotope has a long intrinsic longitudinal relaxation time T-1 on the order of minutes, making it an ideal candidate for hyperpolarization experiments. In the present study we demonstrated that lithium-6 can ...
