Nuclear magnetic resonance imaging has been perform ed with the nuclei 27A1, 51V, and 23Na in some test objects with a 1.5 T imager. Encouraging signal-to-noise ratios have been obtain ed within reasonable measuring times in the imaging and the spectroscopy mode using a commercially available 23Na headcoil.

The success in clinical practice of magnetic resonance imaging (MRI) is a result of the symbiosis of the science of NMR with the computer and the availability of appropriate magnetic fields. A brief survey with some history is presented of NMR phenomena which are basic to the interpretation of MRI signals. Special exotic effects or procedures, such as stochastic NMR and line narrowing techniques of high-resolution NMR spectroscopy have a potential to play a role in future MRI systems.

Background: One of the future applications of magnetic nanoparticles is the development of new iron-oxide-based magnetic resonance imaging (MRI) negative contrast agents, which are intended to improve the results of diagnostics and complement existing Gd-based contrast media. Results: Iron oxide nanoparticles designed for use as MRI contrast media are precisely examined by a variety of methods: powder X-ray diffraction (XRD), transmission electron microscopy (TEM), Raman spectroscopy, Mössbauer spectroscopy and zero-field nuclear magnetic resonance (ZF-NMR) spectroscopy. TEM and XRD measurements reveal a spherical shape of the nanoparticles with an average diameter of 5–8 nm and a cubic spinel-type crystal structure of space group Fd−3m. Raman, Mössbauer and NMR spectroscopy clearly indicate the presence of the maghemite γ-Fe2O3 phase. Moreover, a difference in the magnetic behavior of uncoated and human serum albumin coated iron oxide nanoparticles was observed by Mössbauer spectroscopy. Conclusion: This difference in magnetic behavior is explained by the influence of biofunctionalization on the magnetic and electronic properties of the iron oxide nanoparticles. The ZF-NMR spectra analysis allowed us to determine the relative amount of iron located in the core and the surface layer of the nanoparticles. The obtained results are important for understanding the structural and magnetic properties of iron oxide nanoparticles used as T 2 contrast agents for MRI.
