Nuclear magnetic resonance imaging
Clinical Rheumatology, 1986As compared to other techniques MRI offers many advantages. It enables one to differentiate the nucleus pulposus within the disc and reveals the discal degeneration. It reveals more precisely the relationships with nervous formations and it is invaluable for the detection and exploration of bone tumors and metastasis, of deformations, of the cervico ...

Imaging by nuclear magnetic resonance*
Journal of Physics E: Scientific Instruments, 1988Abstract The subject of nuclear magnetic resonance (NMR) is well known to physicists, and especially chemists and biologists, as an analytical technique for the study of inter- and intra-molecular interactions [1,2]. For those unfamiliar with recent developments, therefore, it is perhaps surprising to learn that NMR techniques have ...

Nuclear magnetic resonance spectroscopy
1986Nuclear magnetic resonance (NMR) spectroscopy is usually combined with infrared (IR) spectroscopy for the complete analysis of the structure of an unknown molecule. IR spectroscopy is used to detect a functional group in the sample, whereas NMR spectroscopy detects number of atoms and their type in sample.

Nuclear magnetic resonance spectroscopy
Analytical Chemistry, 1988Nuclear magnetic resonance (NMR) spectroscopy is one of the most widely used instrumental methods, with applications ranging from the characterization of pure compounds by high-resolution NMR to the diagnosis of disease by magnetic resonance imaging (MRI).

Singlet Nuclear Magnetic Resonance
Annual Review of Physical Chemistry, 2012Nuclear singlet states may have lifetimes that are much longer than the conventional relaxation time of nuclear spin magnetization. This review covers how these states may be generated, observed, and exploited in solution nuclear magnetic resonance (NMR). Potential applications include the study of slow molecular processes, the elucidation of molecular

Introduction to Nuclear Magnetic Resonance
2003This brief guide is not intended as a full explanation of the theory and practice of nuclear magnetic resonance (NMR), on which there are a large number of excellent texts (1-3), but as an introduction to the terms used in the subsequent chapters. The section as a whole does not provide a comprehensive outline of the NMR of organic compounds, which ...

Nuclear magnetic resonance of the brain
Cardiovascular and Interventional Radiology, 1986Recent developments in MRI of the brain are reviewed. Over the past year there has been a general improvement in image quality, a paramagnetic contrast agent has been used in clinical practice, and surface coils have been used more generally in imaging.

Principles of nuclear magnetic resonance
Magnetic Resonance Imaging, 1984The basic principles of nuclear magnetic resonance (NMR) are discussed. The concepts presented include a qualitative quantum-mechanical approach to NMR spectroscopy and a classical-mechanical approach to time-dependent NMR phenomena (relaxation effects).
