What is the difference between NMR and MRI?

Although NMR and MRI may both use radiation to measure, but they refer to quite different concepts. The two scientific acronyms are defined below, along with an examination of their different applications.

What is the definition of NMR?

Nuclear magnetic resonance, or NMR, is a process whereby nuclei are stimulated with radio-frequency photons and subjected to an external magnetic field, which causes them to produce electromagnetic signals. Then, the nuclei re-emit these photons at a certain frequency that reveals the molecule’s particular structure.

The spectroscopic method was created by chemists to detect unidentified molecules, but since then it’s expanded into a wide variety of scientific domains for a variety of purposes.

Using NMR

High-performance NMR spectrometer are currently being used for various applications including chemical analysis as well as to chemically analyse meat samples and determine the species of origin. Norwich’s Quadram Institute Bioscience have used this technique to examine the high-resolution spectrum of fat or oil extracted from a beef sample and have use information to profile the makeup of fatty acids.

According to recently published research “Different meat species exhibit various fatty acid profiles, and these profiles can be utilised to identify the meat species being examined. Due to origin, feeding technique and meat cut, there is naturally occurring diversity across samples of the same meat species in practise. In order to categorise the fatty acid profiles and enable automatic distinction, a chemometrics approach has been devised.

Chemical researchers can learn a lot using the analytical tool known as nuclear magnetic resonance (NMR) spectroscopy. NMR spectrometers can examine the identification, structure, concentration and behaviour of molecules without harming the samples, in contrast to other analytical instruments

What is the definition of MRI?

The initials MRI, which stand for magnetic resonance imaging, is more commonly known to most individuals. A magnetic field and computer-generated radio waves are used in the sophisticated medical imaging procedure to produce precise images of inside organs. The quick and non-invasive process enables medical experts to create intricate images of bodily areas that contain water.

When subjected to radio waves and the magnetic field produced by the MRI scanner, water molecules release electromagnetic waves that play a crucial part in the process. The MRI equipment records these electromagnetic waves and uses them to produce detailed images.

What are the similarities and differences?

NMR and MRI share a common foundation in that they both rely on radiation data to identify unidentified molecules. The method was initially developed during the Cold War, a time when the phrase ‘nuclear’ was unpopular. The phrase was changed to magnetic resonance imaging to make it more approachable for those using it.

MRI generates information based on radiation intensity, whereas NMR generates information based on radiation frequencies. The purpose of NMR spectroscopy is to ascertain the precise chemical composition of materials, whereas the aim of MRI imaging is to produce precise images of the body.
