Relaxometry of brain: Why white matter appears bright in MRI
The remarkable success of magnetic resonance imaging of adult brain relates to the unusually large ratio of the longitudinal relaxation rates 1 / T1 of white and gray matter, ∼2:1 at physiologicalExpand

Relaxation of water protons in the intra‐ and extracellular regions of blood containing Gd(DTPA)
The magnetic field dependence of the longitudinal relaxation rates 1/T1 (NMRD profiles) of blood and plasma from rabbits before and after injection of Gd(DTPA) are reported as a function of magneticExpand

Synthesis and evaluation of a high relaxivity manganese(II)-based MRI contrast agent.
The manganese(II) ion has many favorable properties that lead to its potential use as an MRI contrast agent: high spin number, long electronic relaxation time, labile water exchange. The present workExpand
