Neuronal activity causes local changes in cerebral blood flow, blood volume, and blood
oxygenation. Magnetic resonance imaging (MRI) techniques sensitive to changes in cerebral …

We describe a standard set of quantity names and symbols related to the estimation of kinetic
parameters from dynamic contrast‐enhanced T 1 ‐weighted magnetic resonance imaging …

Knowledge of regional cerebral hemodynamics has widespread application for both
physiological research and clinical assessment because of the well-established interrelation …

… As pointed out by Weisskoff et al. (12), the distinction between this MTT and the first moment
of the concentration time curve obtained from imaging of intravascular bolus passages is, …

Image distortion due to field gradient eddy currents can create image artifacts in diffusion‐weighted
MR images. These images, acquired by measuring the attenuation of NMR signal …

We investigated brain circuitry mediating cocaine- induced euphoria and craving using
functional MRI (fMRI). During double-blind cocaine (0.6 mg/kg) and saline infusions in cocaine-…

Methods are presented to map complex fiber architectures in tissues by imaging the 3D
spectra of tissue water diffusion with MR. First, theoretical considerations show why and under …

MRI was extended to the measurement of changes in oxidative metabolism in the normal
human during functionally induced changes in cellular activity. A noninvasive MRI method that …

… SE and GE phases were estimated as described by Weisskoff et al. (13). In addition, ASE
phases were estimated every 10 ms by combining +,(t) accumulated at 5 ms intervals with …

PURPOSE: To assess the utility of magnetic resonance (MR) cerebral blood volume (CBV)
maps in the evaluation of gliomas. MATERIALS AND METHODS: CBV maps from 19 patients …
