Neuroimagen por Resonancia Magnética.

J.A. Hernández-Tamames

Resumen


In this paper the author explains the basic principles of Magnetic Resonance Imaging and describes the main magnetic resonance modalities applied in brain imaging. MRI provides brain information at different levels: biochemical with spectroscopy, structural with T1 and T2 weighted sequences, Diffusion Tensor Imaging for fiber tractography, functional with BOLD (Blood oxygenant dependent), Perfusion with Arterial Spin Labelling, etc. All of these techniques are allowing the study of the brain tissue maduration and the characterization of the ill brain due to neurodegenerative processes or neurological damage. Some real examples from recent studies at different hospital and research centres, where the author is collaborating, are shown.
