Nuclear magnetic resonance spectroscopy is widely used to determine the structure of organic molecules in solution and study molecular physics and crystals as well as non-crystalline materials. NMR is also routinely used in advanced medical imaging techniques, such as in magnetic resonance imaging (MRI).

What is magnetic resonance spectroscopy and its relationship to signal production?

Introduction. Magnetic resonance spectroscopy (MRS) is an analytical tool that detects radio frequency electromagnetic signals that are produced by the atomic nuclei within molecules. It can be used to obtain in situ concentration measures for certain chemicals in complex samples, such as the living brain.

What is MR testing?

Magnetic resonance (MR) enterography is an imaging test which produces detailed pictures of your small intestine. It may help your doctor diagnose inflammation, bleeding, obstructions and other problems. It is noninvasive and does not use ionizing radiation.
