The authors review the theoretical basis of determination of cerebral blood flow (CBF) using
dynamic measurements of nondiffusible contrast agents, and demonstrate how parametric …

Background The level of evidence for HIV transmission risk through condomless sex in

The T 1 perfusion model has worked well in brain functional studies where flow changes
are measured. Using selective and nonselective inversion pulses, a new method has been …

… We used l(x s,j )∈{0,1}, where 0 is background and 1 is object (brain). The weight w(x i , x
s,j ) assigned to label l(x s,j ) depends on the similarity of P(x i ) to P(x s,j ) and is computed as:(…

PURPOSE: To investigate additional information provided by maps of relative cerebral
blood flow in functional magnetic resonance (MR) imaging of human hyperacute cerebral …

… We assign the capillary length L and volume V, and assume that the current of oxygen
across the capillary membrane is proportional to the difference between plasma oxygen …

Perfusion‐and diffusion‐weighted magnetic resonance imaging was performed during
spontaneous visual auras in four migraineurs. Alterations in relative cerebral blood flow (16–53% …
