[Single-voxel proton spectroscopy using a press sequence with a 135 ms echotime: normal values].

The clinical value of MR spectroscopy is now well established and this technique has been added to the current French classification of medical acts (CCAM). This paper presents a set of normal control values for 3 metabolite ratios obtained using a PRESS sequence with a TE of 135 ms at 1.5T: NAA/Cho, NAA/Cr and Cho/CR.

Proton magnetic resonance neurospectroscopy and EEG cartography in corticobasal degeneration: correlations with neuropsychological signs.

Objective: To document the asymmetrical functional brain lesions in corticobasal degeneration (CBD) using proton magnetic resonance neurospectroscopy (MRS) and EEG cartography (EEGq).

Methods: Eight patients with probable CBD were included in the study after full neurological examination and extensive neuropsychological testing, single photon emission computed tomography, anatomical x ray tomodensitometry (TDM), magnetic resonance imaging, and MRS examination.

Results: MR spectra were abnormal in all seven patients in whom the examination could be completed.

Correlative anatomic and CT study of the lumbar lateral recess.

The lumbosacral nerve roots and their relation to the lateral recess in the lumbar region were studied by computed tomography both in anatomic specimens from six cadavers and in vivo in 100 patients with or without disk herniation. The anatomic and tomodensitometric correlations are discussed. The normal morphology and contents of the lumbar spinal canal can be used as a guide to radiologic diagnostic exploration, which in turn can indicate the etiology and extent of lumbar sciatica and the course of treatment.

Tolosa-Hunt syndrome.

Ten cases of painful ophthalmoplegia are reported. In all cases pain marked the onset of the disease; the condition was mostly unilateral. Recurrence and dramatic response to steroid therapy were more constant features than angiographic findings which may be completely normal.

[Pubertal prolactin adenoma. Eight cases (author's transl)].

Among 70 operated patients with a histologically verified prolactin secreting adenoma, 8 cases (7 girls, 1 boy) presented the onset of clinical signs before, during or immediately after puberty. Two different clinical syndromes were detected. In the younger patient group (4 cases), the first clinical signs at the onset of puberty were arrest of both growth and pubertal development.

[Role of computerized axial tomography in neuroradiology. 1st results].

On the basis of their experience, the autors report the results obtained after 1500 examinations in the study of space occupying hemispheric lesions and in the study of cerebral atrophy.

[Study of epilepsy by computer controlled transverse axial tomography of the brain].

The value of computerized azial tomography of the encephalon is considered:--Firstly, in relation to the different electro-clinical varieties of epilepsy (essentially primary, secondary and partial) where it provides information of a high degree of precision concerning the topography, frequency and size of morphological abnormalties of the encephalon.--Secondly, in relation to the various aetiological possibilities (tumour, post-traumatic, post-ischaemic, post-infective, et cetera). This new method is of considerable to specify an aetiology almost unknown up to the present time: post-ischaemic occipital porencephaly secondary to perinatal or infantile occlusion of the posterior cerebral artery.

Post mortem investigation of the vertebrabasilar system.

The shape, origin, termination and number of the main arteries of the vertebrobasilar system have been analysed in 30 anatomic specimens by dissection of the injected vessels and by radiography. Five projections are described for identifying the different regions of the brain stem and cerebellum through the appearance of the arteries. A technique is proposed for obtaining a 'true' a.

[Angiographic study of cerebral convolutions and their area of vascularization].

The authors demonstrate the facility with which the principal fissures and sulci of the brain can be angiographically localized by reference to characteristic loops and bends in the courses of the branches of the anterior, middle, and posterior cerebral arteries. The study is based upon dissections of 150 human brains in which the arteries of interest were selectively injected. A propos to this anatomic-angiographic correlation the authors also describe the vascular territories of each cortical branch and propose a simple procedure for the evaluation of these territories during cerebral angiography.
