Magnetic resonance imaging is widely used in the sciences and medicine, with the same basic underlying detection principle: the need for intimate coupling between nuclear magnetization in the sample under investigation and the detector. This study now shows a new detection principle, where the nuclear magnetization signal can be excited (and detected) via a long-range interaction utilizing travelling radiofrequency waves in a suitably modified MRI system. This approach offers more uniform coverage of larger samples.
