    Quantitative fMRI

    Blood oxygenation level-dependent (BOLD) functional magnetic resonance imaging (MRI) has proven to be a powerful and sensitive tool for noninvasively detecting neural activity changes in the brain. However, th...

    Involvement of striate and extrastriate visual cortical areas in spatial attention

    We investigated the cortical mechanisms of visual-spatial attention while subjects discriminated patterned targets within distractor arrays. Functional magnetic resonance imaging (fMRI) was used to map the bou...

    Biophysical Bases of Elasticity Imaging

    Elasticity imaging is based on two processes. The first is the evaluation of the mechanical response of a stressed tissue using imaging modalities, e.g. ultrasound, magnetic resonance imaging (MRI), computed t...

    Relationships Between Viscosity Factors and Cerebral Blood Flow and Porous Bed Viscometry in Normals and Stroke Prone Subjects

    The main determinants of whole blood viscosity are hematocrit and fibrinogen. This communication discusses the relationship between these factors and cerebral blood flow (CBF) and porous bed viscometry (PBV). ...
