Abstract

Nuclear magnetic resonance (NMR) is a property exhibited by paramagnetic nuclei, i.e., those with an odd number of nucleons, in a strong magnetic field. It is induced by the application of bursts of radiofrequency waves, the frequency necessary for excitation depending on the nuclei in question (usually hydrogen in clinical imaging) and the strength of the magnetic field. Use of this property for imaging purposes (MRI) entails detection and spatial coding of the NMR signal, which is itself of radiofrequency. Encoding is achieved by introducing transient gradients across the magnetic field, via passage of electrical currents through coils adjacent to the patient (Pykett et al. 1982).
