Patients showing typical Chiari malformation type 1 (CM1) signs and symptoms frequently
undergo cranial and cervical MRI. In some patients, MRI documents> 5 mm of cerebellar …

Flow imaging with cardiac-gated phase-contrast MR has applications in the management of
neurologic disorders. Together with computational fluid dynamics, phase-contrast MR has …

BACKGROUND AND PURPOSE: Ependymoblastoma is a malignant embryonal tumor that
develops in early childhood and has a dismal prognosis. Categorized by the World Health …

Object The effect of craniovertebral decompression surgery on CSF flow dynamics in
patients with Chiari malformation Type I (CM-I) has been incompletely characterized. The …

OBJECTIVE The mesodermal derangement in Chiari Type I malformation (CMI) has been
postulated to encompass the cervical spine. The objectives of this study were to assess the …

Objective To describe tonsillar blackout sign (TBS) on three-dimensional (3D)-SPACE,
evaluate its performance in identifying Chiari malformation (CM1) as diagnostic marker, and …

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 …

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 …

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 …
