    "abstract": "The main findings of the european PHIL project (Polarised Helium to Image the\nLung) are reported. State of the art optical pumping techniques for polarising\n^3He gas are described. MRI methodological improvements allow dynamical\nventilation images with a good resolution, ultimately limited by gas diffusion.\nDiffusion imaging appears as a robust method of lung diagnosis. A discussion of\nthe potential advantage of low field MRI is presented. Selected PHIL results\nfor emphysema are given, with the perspectives that this joint work opens up\nfor the future of respiratory medicine.",
