While not as commonplace as comprehensive metabolic panel testing, NMR technology helps determine specialized parameters for lipoprotein and lipid testing. Publications describing its use in clinical laboratories began to appear in the literature in the 1980s. NMR spectroscopy can be used to measure the size and density of lipoprotein molecules, and the data it generates improves the risk assessment for atherosclerotic cardiovascular disease compared with low-density lipoprotein cholesterol levels. However, even after a few decades of research and development, use of NMR for lipoprotein profiling still lacks standardization and comparability to other methods. A 2018 article published in Clinical Chemistry noted that NMR-based measurements lacked comparability, even within the technology, and that the software used for data analysis was likely part of the problem.

If this problem persists please contact customer support By the early 1980s nuclear magnetic resonance techniques had begun to be used in medicine to visualize soft tissues of the body. This application of NMR, called magnetic resonance imaging (MRI), presented a hazard-free, noninvasive way to generate visual images of thin slices of the body by measuring the nuclear magnetic moments of ordinary hydrogen nuclei in the body’s water and lipids (fats). NMR images show great sensitivity in differentiating between normal tissues and diseased or damaged ones. By the late 1980s MRI had proved superior to most other imaging techniques in providing images of the brain, heart, liver, kidneys, spleen, pancreas, breast, and other organs. MRI provides relatively high-contrast, variable-toned images that can show tumours, blood-starved tissues, and neural plaques resulting from multiple sclerosis. The technique presents no known health hazards, but it cannot be used on individuals who have cardiac pacemakers or certain other metal-containing devices implanted in their bodies.Nuclear magnetic resonance involves the immersion of nuclei in a magnetic field, and then matching the frequency at which they are precessing with electromagnetic radiation of exactly the same frequency so that energy absorption can occur.

See more of Nuclear Magnetic Resonance (NMR) on Facebook One area in which MRS has shown particular promise is in the diagnosis of congenital metabolic disorders. Given the large number of potential metabolites in the body and the high inter-individual variability in analyte concentrations among patient populations, MRS offers useful data. For example, within the brain, MRS recognizes metabolites such as N-acetyl aspartate, creatine, choline, myoinositol, lactate, glutamate, and glutamine molecules. Figure 1 illustrates the typical spectra seen in a healthy brain.

In addition to its use in discerning congenital metabolic disorders, MRS is very useful in characterizing the metabolism of tumor cells and inflammatory conditions. MRS has been used to detect the presence of brain, breast, and gastrointestinal tumors (Figure 2). Neuropsychiatric applications of MRS in evaluating systemic lupus erythematosus and multiple sclerosis, in targeting brain areas for treating epilepsy, and in predicting risk for Alzheimer’s disease and dementia also have been described in the literature.

Understanding NMR Spectroscopy James Keeler John Wiley & Sons (2006,2007) Nuclear magnetic resonance (NMR) spectroscopy has a storied history. Edward Purcell and Felix Bloch developed the NMR technology in the late 1940s, for which they earned a Nobel prize in physics. The principle underlying this approach is that radio waves excite intramolecular magnetic fields around atomic nuclei, resulting in chemical shifts and changes in resonance frequency. These changes in resonance are akin to how potassium or sodium give off different wavelengths of light when heated in flame emission photometry. nuclear magnetic resonance spectroscopy chưa có trong Cambridge Dictionary.

nuclear magnetic resonance. spectroscopic technique relying on the energy difference between the quantum spin states of electrons when exposed to an external magnetic field In addition to its role in specialized lipoprotein measurements, NMR has been explored for point-of-care testing. Researchers have proposed using magnetic nanoparticles to enhance or amplify the signal, called microNMR, in order to bring NMR to bedsides or clinics. In fact, in 2014 the Food and Drug Administration approved an NMR-based platform called the T2Dx, from T2Biosystems, with one panel for identifying sepsis-causing bacterial infections and another for fungal pathogens in whole blood. These platforms are capable of detecting the organisms within 3-5 hours of test initiation. Researchers are also working on applications for detecting Lyme disease and carbapenem-resistant organisms.

Historically, analysis of inborn errors of metabolism has been based on a targeted approach to diagnostic workflows. Research, though, typically utilizes more untargeted processes in order to take advantage of the deep datasets provided by NMR-based analysis. The evolution or translation of these research findings into clinically actionable data has yet to occur. Tebani and colleagues have used the phrase “the curse of dimensionality” to describe the issue of transforming NMR-based studies’ complex, highly dimensional datasets into the more targeted questions typical in the differential diagnosis of a metabolic disease.

To date, other than assessing lipid metabolism, applications of NMR in metabolic disease testing remain in the whole body/tissue imaging arena. NMR-based testing of blood and other fluids is largely stuck in discovery, translational, or proof-of-concept phases. Several authors have put forth rationales to explain NMR’s lack of uptake, and the common thread appears to be data analysis and informatics limitations. Combined with a paradigm shift moving from targeted to untargeted screening workflows and the issues with harmonization of results, it’s not unreasonable to see why NMR still has not become mainstream. Topics include nuclear spin, nuclear magnetic dipole, nuclear magnetic resonance, NMR spectrometer, ma..
