Quantitation of renal perfusion using arterial spin labeling with FAIR-UFLARE.
TL;DR: Considering the relatively high resolution of 2x2x10 mm3, the ability to quantify perfusion, and the lack of ionizing radiation and contrast media, this technique should prove useful in diagnosing renal pathologies that are associated with reductions in tissue perfusion.

Spatially Resolved Transverse Relaxation Times T2 of Human Articular Cartilage – an in vitro and in vivo MRI Study
TL;DR: It is demonstrated that T 2 maps of articular cartilage can be acquired in vivo with good precision and may have potential for noninvasive assessment of material properties of cartilage, e.g. to study degenerative changes with aging and disease.

TL;DR: The Raman spectra of the OH-stretching region of liquid H2O and 10% HDO have been obtained between -50 and +100°C at pressures up to 240 MPa, extending into the deeply supercooled region as discussed by the authors .
Detection of changes in cartilage water content using MRI T2-mapping in vivo
TL;DR: Small, physiologic changes in the water content of patellar cartilage and the concomitant change in proteoglycan and collagen density following exercise can be detected using MRI.
