title: Diffusion and perfusion in high resolution NMR imaging and microscopy.
abstract: Diffusion and perfusion phenomena under strong gradient fields (approximately 100 G/cm) are examined in high resolution nuclear magnetic resonance (NMR) imaging and microscopy, where diffusion-associated signal attenuation predominates over T1 and T2 relaxation decays. Image contrast based on the diffusion and microcirculation is discussed with experimental results obtained with a 7.0-T microscopy system. Ultimate resolution limit due to diffusion is investigated in high resolution NMR imaging and microscopy.
