Journal of Molecular Structure, 2007 Abstract Proton NMR spin–lattice relaxation times T1 were measured for urea as a function of temperature. An activation energy of 46.3 ± 4.7 kJ/mol was extracted and compared with the range of 38–65 kJ/mol previously reported in the literature as measured by different magnetic resonance techniques.

Characterization of Prostate Microstructure Using Water Diffusion and NMR Relaxation
Frontiers of Physics, 2018 For many pathologies, early structural tissue changes occur at the cellular level, on the scale of micrometers or tens of micrometers. Magnetic resonance imaging (MRI) is a powerful non-invasive imaging tool used for medical diagnosis, but its clinical ...
