BACKGROUND: Cervical spinal canal tapering may increase CSF velocities and pressures.
One report suggests that the cervical spinal canal tapers more steeply in patients with Chiari …

BACKGROUND AND PURPOSE: Upper cervical spinal canal dimension may have a role in
abnormal CSF dynamics in patients with Chiari I malformation. We attempted to measure …

BACKGROUND AND PURPOSE: The cause of syringomyelia in patients with Chiari I
remains uncertain. Cervical spine anatomy modifies CSF velocities, flow patterns, and …

BACKGROUND AND PURPOSE: Steeper tapering of the cervical spinal canal as
documented in recent studies is thought to have a role in the pathophysiology of Chiari …

Purpose The relationship between syringomyelia and presyrinx, characterized by edema in
the spinal cord, has not been firmly established. Patients with syringomyelia have abnormal …

Background When the neck is flexed in patients with Chiari I malformation, herniated tonsils
descend, impacting the spinal canal, and the clivus-canal angle changes and compresses …

Study Design. Conventional and phase-contrast magnetic resonance (MR) imaging were
used to evaluate the morphology and cerebrospinal fluid (CSF) flow dynamics at …

Introduction The cervical spine in Chiari I patient with syringomyelia has significantly
different anteroposterior diameters than it does in Chiari I patients without syringomyelia. We …

Chiari I patients have increased CSF velocities in the foramen magnum due hypothetically to
increased pressure gradients or reduced flow resistance. We calculated flow resistance in …

BACKGROUND AND PURPOSE: Phase-contrast MR imaging (PCMR) has only partially
characterized cyclic CSF flow and pressure, which, hypothetically, have a role in the …
