Topography of the cortical motor hand area: prospective study with functional MR imaging and direct motor mapping at surgery.
PURPOSE To localize the cortical motor hand area with functional magnetic resonance (MR) imaging and electrical stimulation at surgery and to detect changes due to central lesions. MATERIALS AND… Expand
Investigation of facial motor pathways by electrical and magnetic stimulation: sites and mechanisms of excitation.
A refined technique is described for non invasive examination of the facial motor pathways by stimulation of the extra- and intracranial segment of the facial nerve and the facial motor cortex.… Expand
Detailed magnetic resonance imaging anatomy of the cisternal segment of the abducent nerve: Dorello's canal and neurovascular relationships and landmarks.
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-state (3-D… Expand
Management of obstructive hydrocephalus secondary to posterior fossa tumors by steroids and subcutaneous ventricular catheter reservoir.
In 61 patients (38 adults and 23 children) with surgically treatable tumors of the posterior fossa and obstructive hydrocephalus the following treatment for hydrocephalus was employed: a high dose of… Expand
Mapping of motor cortex gyral sites non-invasively by transcranial magnetic stimulation in normal subjects and patients.
Transcranial stimulation offers the opportunity to replace a standard clinical method of invasive brain cortical mapping. A figure '8' magnetic coil with a 1-3-cm area of stimulation is combined with… Expand
Safe surgery of lesions near the motor cortex using intra-operative mapping techniques: a report on 50 patients
SummaryIn 50 patients lesions located in or adjacent to the motor strip were microsurgically removed with the help of intra-operative electrophysiological mapping of the sensorimotor cortex. Mapping… Expand
Accuracy of high resolution computed tomography in direct diagnosis of cerebral aneurysms
SummaryWith high resolution computed tomography (CT) of the skull, performing rapid series of 1.5 mm slices during an intravenous bolus injection of contrast medium, an angiography-like image… Expand
Heschl's gyrus - Anatomic description and methods of identification on magnetic resonance imaging
Purpose: To describe the number, anatomic shape, and location of Heschl's gyrus, to evaluate its relation to hemispheric asymmetries, and to define criteria for identifying it with magnetic resonance… Expand

The authors evaluated the anatomical location of the central sulcus (CS) in 24 cerebral hemispheres (eight in which tumors were located centrally, 16 in controls) using: 1) classic anatomical… Expand
Visualization of cranial nerves I–XII: value of 3D CISS and T2-weighted FSE sequences
Abstract. The aim of this study was to evaluate the sensitivity of the three-dimensional constructive interference of steady state (3D CISS) sequence (slice thickness 0.7 mm) and that of the… Expand
