The interpretation of conventional spin-echo and gradient-echo MR images of intracranial
vascular lesions can be complex and ambiguous owing to variable effects on image …

Spin-echo phase images have been shown to be sensitive to blood flow and have been
used to differentiate slow flow from thrombus, with an apparent advantage in comparison …

The authors describe their use of phase-contrast MRA to depict vascular anatomy and to
define the direction of blood flow. Documentation of flow reversal can provide information …

To investigate the role of the gradient-echo (GRE) technique in clinical intracranial magnetic
resonance (MR) imaging, 63 patients with a variety of vascular intracranial lesions were …

The authors assessed the clinical utility of a magnetic resonance angiography technique in
the evaluation of intracranial circulation. Eighteen patients with a low likelihood of …

Twenty patients with known or suspected intracranial vascular lesions were evaluated with
gradient recalled MR (GRASS) imaging, and the results were compared with those obtained …

Twenty-seven patients with 14 aneurysms and 17 vascular malformations were each
examined with both time-of-flight (TF) and phase-contrast (PC) magnetic resonance …

Gradient-recalled acquisition in the steady state (GRASS) MR images, obtained in four
patients with angiographic evidence of successful occlusion of cerebral arteriovenous …

The authors assessed regional cerebral blood flow dynamics with magnetic resonance (MR)
imaging enhanced with gadolinium diethylenetriaminepentaacetic acid (DTPA). After bolus …

Magnetic resonance (MR) angiography constitutes a group of evolving MR imaging
techniques that can be used to directly image flow in arteries, veins, and cerebrospinal fluid …
