Abstract
Magnetic Resonance Imaging is one of the most versatile experimental techniques in chemistry, physics and biology, providing insight into the structure and dynamics of matter at the molecular scale. A group led by Klaas Pruessmann at ETH Zurich (Brunner, D.O. et al. Travelling-wave nuclear magnetic resonance. Nature 457;994:2009) has now demonstrated an alternative approach that radically departs from the conventional view of MRI as a near-field, inductive technique. This approach also required that radiofre-quency wave is propagated from an antenna positioned at one end of the cylindrical magnet; this wave travels through the specimen within the bore of the magnet, producing signals that are received either by the same antenna or by another one positioned at the opposite end. The resulting instrument considerably extends the scale of imaging possible with Magnetic Resonance Imaging,…
