Rapid MR relaxometry using deep learning: An overview of current techniques and emerging trends
NMR in Biomedicine, 2020 Quantitative mapping of MR tissue parameters such as the spin‐lattice relaxation time (T1), the spin‐spin relaxation time (T2), and the spin‐lattice relaxation in the rotating frame (T1ρ), referred to as MR relaxometry in general, has demonstrated ...

Mucosal‐Associated Invariant T Cells in Rheumatic Diseases
Arthritis &Rheumatology, EarlyView.Mucosal‐associated invariant T (MAIT) cells are innate‐like T cells defined by their semi‐invariant T cell receptor and restriction by the major histocompatibility complex class I–related molecule (MR1). These cells are primarily activated by microbial‐derived metabolites presented by MR1 or by cytokines.

Journal of Magnetic Resonance Imaging, EarlyView.ABSTRACT Background MRI contrast agents enhance lesion characterization by altering tissue relaxation properties. However, quantitative assessment of contrast enhancement is limited by variability in contrast administration parameters, and lack of efficient and precise contrast concentration independent relaxivity (r1, r2) measurement techniques.

Characterisation of porous solids using small-angle scattering and NMR cryoporometry [PDF]
, 2004 The characteristics of several porous systems have been studied by the use of small-angle neutron scattering [SANS] and nuclear magnetic resonance [NMR] techniques. The measurements reveal different characteristics for sol-gel silicas, activated carbons
