Analysis of the brain-stem white-matter tracts with diffusion tensor imaging
The authors have reviewed the diffusion tensor imaging (DTI) of the brain stem in 19 subjects, consisting of 15 normal volunteers and four multi-system atrophy patients. The study was performed with 1.5 T MRI ...

MRI of the intracranial corticospinal tracts in amyotrophic and primary lateral sclerosis
Our aim was to investigate the corticospinal tracts (CST) in motor neurone disease, using MRI, and to correlate findings with clinical data. We studied 31 patients with amyotrophic (ALS) and eight with primar...

Contrast-enhanced magnetisation transfer MRI in metastatic lesions of the brain
Our purpose was to compare prospectively the sensitivity of contrast-enhanced magnetisation transfer (MT) MRI and gradient-echo (GE) T1-weighted images in metastatic disease of the brain. We studied 52 patien...

MRI of intracranial chordomas. Extent of tumour and contrast enhancement: criteria for differential diagnosis
We present six proven cases of chordoma of the clivus studied by CT and MRI, with special attention to the extent of the tumour and to the signal intensity after intravenous gadolinium. MRI is the best techni...

Theoretical situation of brain white matter tracts evaluated by three-dimensional MRI
An accurate knowledge of cerebral anatomy is important in order to evaluate the precise location of a cerebral lesion. Cortical structures are identified by knowledge of the adjacent gyri and sulci; however, w...

Epidural arteriovenous fistula with perimedullary venous drainage: case report
We report an epidural arteriovenous fistula (without dural involyment) whose venous drainage was via perimedullary reflux, treated by embolisation.

Cortical region of interest definition on SPECT brain images using X-ray CT registration
We present a method for brain single photon emission computed tomography (SPECT) analysis based on individual registration of anatomical (CT) and functional (133Xe regional cerebral blood flow) images and on the ...

Spontaneous dissection of both extracranial internal carotid arteries
Neurological examination and Doppler sonography of a 50-year-old patient were suggestive of a spontaneous dissection of the left internal carotid artery (left-sided headaches, amaurosis fugax, Horner's syndrom...

Magnetic resonance imaging of the brain stem
Magnetic resonance imaging of 30 normal volunteers' posterior fossae was performed on a CGR Magniscan machine with a magnetic field strength of 0,5 Tesla. We chose the inversion recovery signal with a Tr of 2,...

MR imaging of epidermoid cysts
After a short review of literature, MRI assessments of four cases of epidermoid cysts (EC) are reported. EC, (characterized in computed tomography by hypo or iso-density areas nonenhanced by contrast), are cha...

Neuroradiological study of hemangiopericytomas
The authors report four cases of hemangiopericytoma. The preoperative diagnosis is strongly suggested by the use of selective angiography and post-iodine CT scan which provide images often rather similar to hi...

Anatomical basis of the microsurgical approach to the pineal gland
The microanatomic study of the pineal region was made from 18 cadaver brains. The purpose of this paper is to describe the surgical anatomy needed to approach this area, which is deeply located and in the midl...

Cerebral Contusions — Correlations Between C. T., Angiography, and the Vascular Anatomy of the Brain and Skull Base
87 patients with cerebral contusion were examined by computed tomography (CT). The images were then correlated with the vascular anatomy of the brain or of the large vessels in the base. Sixty-seven of the 87 ...
