## Abstract Nuclear Overhauser effect (NOE) enhancements and relaxation times of ^31^P metabolites in human calf were measured in 12 volunteers (4 men and 8 women) at 1.5 T using a dual tuned fourβring birdcage. The NOE enhancements of inorganic phosphate (__P__~1~), phosphocreatine (PCr), Ξ³β, Ξ±β,

β¦ Synopsis
Robust pre-contrast reference T1 values using ShMOLLI in 231 normal human controls aged 11 to 81 years demonstrate little dependence on gender, age or heart rates.

The objective of this study was to implement a clinically relevant multi-slice multi-echo imaging sequence in order to quantify multicomponent T2 relaxation times for normal volunteers at both 1.5 and 3 T. Multi-echo data were fitted using a nonnegative least square algorithm. Twelve echo data with
## Abstract __T__~2~ of cortical gray matter is generally assumed to be longer than that of white matter. It is shown here that this is not the case in the occipital lobe, but that this effect is often obscured at lower resolution and concealed in standard __T__~2~βweighted images. Using a highβres
