| Zusammenfassung | For characterizing lung diseases or optimizing artificial respiration there is great interest in the dynamics of gas flow to and gas diffusion within the lungs. Several groups model these parameters numerically but no techniques have been available for a long time to compare their results to non-invasive in vivo conditions. Both quantities, flow and diffusion, are accessible by standard proton MR techniques. ADC measurements of hyperpolarized rare gases (mainly 3He) are well described and already used in clinical studies. Up to now in vivo measurements of gas-flow velocities using phase encoding techniques are rarely shown. |
