MRI T2 relaxometry and quantification of iron in central grey matter structures in patients suffering from multiple sclerosis

The aim of this work is to present new MRI techniques in MS diagnostics, which among others include quantitative processing of conventional MR scans. We focused especially on MRI T2 relaxometry. T2 relaxometry is non-invasive method...

1H NMR relaxometry study of a rod-like chiral liquid crystal in its isotropic, cholesteric, TGBA*, and TGBC* phases

Molecular dynamics of the new lactate derivative exhibiting TGBA, TGBC1 and TGBC2 mesophases was studied by 1H NMR relaxometry. This investigation of a chiral liquid crystal showing such rich variety of frustrated mesophases was done for the...
