Abstract Intravoxel Incoherent Motion (IVIM) refers to translational movements which within a
given voxel and during the measurement time present a distribution of speeds in orientation …

Mapping tissue microstructure with MRI holds great promise as a noninvasive window into
tissue organization at the cellular level. Having originated within the realm of diffusion NMR …

Simultaneous multislice imaging (SMS) using parallel image reconstruction has rapidly
advanced to become a major imaging technique. The primary benefit is an acceleration in …

Resting-state functional magnetic resonance imaging (rfMRI) allows one to study functional
connectivity in the brain by acquiring fMRI data while subjects lie inactive in the MRI …

Layer-dependent fMRI allows measurements of information flow in cortical circuits, as
afferent and efferent connections terminate in different cortical layers. However, it is …

Functional magnetic resonance imaging (fMRI) is a class of imaging methods developed to
demonstrate regional, time-varying changes in brain metabolism. 1–3 These metabolic …

A biomechanical model is presented for the dynamic changes in deoxyhemoglobin content
during brain activation. The model incorporates the conflicting effects of dynamic changes in …

Recently, several implementations of arterial spin labeling (ASL) techniques have been
developed for producing MRI images sensitive to local tissue perfusion. For quantitation of …

Intersubject variability and subtle differences in experimental design can lead to variable
results in studies of cognitive processes such as reading. To accurately identify the neural …

Neural activity in the brain is accompanied by changes in cerebral blood flow (CBF) and
blood oxygenation that are detectable with functional magnetic resonance imaging (fMRI) …
