Diffusional kurtosis imaging: The quantification of non-gaussian water diffusion by means of magnetic resonance imaging
TL;DR: From the study of six healthy adult subjects, the excess diffusional kurtosis is found to be significantly higher in white matter than in gray matter, reflecting the structural differences between these two types of cerebral tissues.

TL;DR: This review provides a summary statement of recommended implementations of arterial spin labeling (ASL) for clinical applications and describes the major considerations and trade‐offs in implementing an ASL protocol and provides specific recommendations for a standard approach.
Determining the longitudinal relaxation time (T1) of blood at 3.0 Tesla
TL;DR: It was found that 1/T1 in s−1 was linearly dependent on hematocrit (Hct) within a normal range of 0.38–0.46 and when a head coil transmit/receive setup was used, radiation damping caused a slight reduction of the measured T1 values.

TL;DR: Comparison of the hemodynamic responses of VASO‐fMRI, cerebral blood flow (CBF)‐based fMRI, and blood oxygenation level‐dependent (BOLD) fMRI indicates both arteriolar and venular temporal characteristics in VASo.

TL;DR: Cognitive gains were manifested in the exercise group's improved immediate and delayed memory performance from T1 to T3 which also showed a significant positive association with increases in both left and right hippocampal CBF identified earlier in the time course at T2.
