BACKGROUND AND PURPOSE: The insula is important for gustatory sensation, motor speech
control, vestibular function, and sympathetic control of cardiovascular tone. The purpose …

BACKGROUND AND PURPOSE: Postural headache most often occurs after lumbar puncture
as post–lumbar puncture headache (PLPH) or, rarely, spontaneously as spontaneous …

Object. The purpose of this study was to determine the diagnostic accuracy of high-field (1.5-tesla)
magnetic resonance (MR) imaging in the assessment of hyperacute (< 12 hours after …

Superior oblique myokymia is a rare movement disorder thought to be caused by vascular
compression of the trochlear nerve. Direct display of such neurovascular compression by …

PURPOSE: To assess the anatomic features and vascular relationships of the proximal
portion of the cisternal segment of the trochlear nerve. MATERIALS AND METHODS: In 30 …

Object. The goal of this study was to identify reliably the cisternal segment of the abducent
nerve by using the three-dimensional Fourier transform constructive interference in steady-…

Object. The trigeminal nerve conducts both sensory and motor impulses. Separate superior
and inferior motor roots typically emerge from the pons just anterosuperomedial to the entry …

BACKGROUND AND PURPOSE: Visualization of the trigeminal system is important for imaging
diagnosis but technically challenging. We assessed how well the trigeminal ganglion, its …

We investigated the usefulness of echo-planar imaging (EPI) as well as T2 * -weighted and
diffusion-weighted MRI (DWI) to identify hyperacute hemorrhage (within 24 h after ictus) in …

Object. The thin hypoglossal nerve can be very difficult to distinguish on magnetic resonance
(MR) images. The authors used a combination of sequences to increase the reliability of …
