Magnetic resonance (MR) spectroscopy is an analytical method used in chemistry that enables the identification and quantification of metabolites in samples. It differs from conventionalMR imaging in that spectra provide physiologic and chemical information instead of anatomy. MR spectroscopy and MR imaging have their origin in nuclear magnetic resonance (NMR). NMR was first described in 1946 si...
Simultaneous analysis of explosives to identify, determine the purity and eliminate environmental pollution requires rapid, simple and cheap methods. Spectrophotometries method (UV-Vis), high-field proton nuclear magnetic resonance (1H-NMR), Raman spectroscopy and near infrared (NIR) are common methods that are applicable in two ways of direct and indirect in simultaneous analysis. In this poin...
Using noninvasive magnetic resonance imaging techniques to accurately evaluate the grading and cellularity of gliomas is beneficial for improving the patient outcomes. Amide proton transfer imaging is a noninvasive molecular magnetic resonance imaging technique based on chemical exchange saturation transfer mechanism that detects endogenous mobile proteins and peptides in biological tissues. Be...
