Diffusion-Weighted Magnetic Resonance Imaging
Magnetic resonance imaging (MRI) is a technique based on the contents and relaxation features of water in tissues. In basic MRI sequences, diffusion phenomenon of water molecules is not taken into account although it has a notable influence in the relaxation times, and therefore in the signal intensity of images. In fact, MRI techniques that take advantage of water diffusion have experienced a huge development in last years. Diffusion-weighted imaging (DWI) has spectacularly evolved reaching nowadays a great impact both in clinical and preclinical imaging—especially in the neuroimaging field—and in basic research. We present here a protocol to perform DWI studies in a high-field preclinical setup.
