    Notes: Thin film diffusion couples (Pd-Cu, individual layer thicknesses: 50 nm) have beenprepared by DC-magnetron sputtering on silicon substrates coated with amorphous inter-layers(Si3N4 on top of SiO2). The microstructural development, phase formation and the stress evolutionduring diffusion annealing have been investigated employing Auger-electron spectroscopy incombination with sputter depth profiling, ex-situ and, in particular, in-situ X-ray diffractionmeasurements. Upon annealing at relatively low temperatures (175°C to 250°C) for durations up to100 hours, considerable diffusional intermixing occurs. Interdiffusion is accompanied by thesequential formation of a new phase (Cu3Pd). The detected stress changes are discussed in terms ofpossible mechanisms of stress generation

    Description / Table of Contents: Résumé La latéralisation de la partie postérieure du lobe temporal et du lobe pariétal inférieur chez l'enfant a été étudiée en TDM sur 276 cas et comparée avec celle de l'adulte dans 371 cas. Les images TDM des ramifications médullaires de la substance blanche cérébrale furent analysées. Chez l'enfant en dessous de 5 ans d'âge, le planum temporale gauche est plus postérieur que le droit dans 56 % des cas; le droit est plus postérieur dans 21 %. L'asymétrie du gyrus temporal moyen est similaire à celle du planum temporal. La plicature (gyration) du lobule pariétal inférieur est massive et importante du côté gauche dans 63 % et dans 8 % du côté droit, chiffre à peu près identique à ceux de l'adulte. Le degré de visualisation du sillon intrapariétal est inférieur à celui de l'adulte mais la meilleure visualisation du côté gauche est un phénomène commun quel que soit l'âge incriminé. Ces altérations droitegauche semblent être le substrat morphologique des processus de localisation de la fonction auditive dans ces zones d'association.
    Notes: Summary Lateralization of the posterior temporal lobe and inferior parietal lobule in childhood was studied on CT of 276 cases and compared with those in adulthood of 371 cases. CT images were analized based on the morphological features of medullary branches of the cerebral white matter. In children below 5 years of age, the left planum temporale was already more posteriorly located than the right in 56%, while the right was more so in 21%. The asymmetry of the middle temporal gyrus was similar to those of the planum temporale. The folding of the inferior parietal lobule was extensive and intricate on the left side in 63% and on the right side in 8% of children, almost identical to those in the adult. The visualization rates of the intraparietal sulcus were lower compared to those of the adult, but the higher visualization of the left side was a common tendency regardless of age. These alterations in left-right asymmetry seemed to be a morphologic substratum indicating the processes of localization of auditory function to those association areas.

    Description / Table of Contents: Résumé L'auteur insiste sur la distribution entre les branches médianes et les autres artères opacifiées par angiographie vertébrale. Cette distinction permet dans une certaine mesure de reconnaître la nature d'une masse expansive de la fosse postérieure.
    Abstract: Zusammenfassung Bei der Vertebralis-Arteriographie ist es ein besonderes Problem, die Mittellinie des Kleinhirns zu bestimmen und festzustellen, ob ein raumfordernder Prozeß von einer Kleinhirnhemisphäre oder von der Mittellinie ausgeht. Die Unterscheidung zwischen den medialen Ästen von Kleinhirngefäßen und anderen Arterien ist besonders wichtig, da dadurch die Art eines raumfordernden Prozesses im Bereich der hinteren Schädelgrube festgestellt werden kann.
    Notes: Summary The distinction between medial branches of the cerebellum and other arteries opacified in vertebral arteriography should be of clinical importance, because this distinction can be regarded to indicate in some measure the nature of a mass in the posterior fossa.

    Basiparallel cut by pneumoencephalotomography and cerebellar atrophy (1978)

    Notes: Summary The basiparallel cut is a nearly horizontal slice of the posterior fossa used in air study and the structures are observed on a plane parallel to the clivus. Total shrinkage of the cerebellum, with or without fourth ventricle dilatation, was found in cases of olivopontocerebellar atrophy, some intoxications, and a few senile subjects. Some atrophy of paleocerebellar portions was seen in Holmes-type degeneration. Another pattern was symmetric shrinkage of neocerebellar lobules and relatively specific for the cases of ‘multiple system atrophy’ such as progressive supranuclear palsy, striatonigral degeneration, Marie's ataxia, etc. Loss of the superior cerebellar peduncle was clearly demonstrated in this view.

    MRI findings in the mild type of mucopolysaccharidosis II (Hunter's syndrome) (1990)

    Notes: Summary Neuroradiological findings in a 44-year-old male with the typical mild type of Hunter's disease are reported. Cranial MRI revealed patchy areas of increased and decreased signals in T1- and T2-weighted images in the thalamus and the basal ganglia giving rise to a honey comb-like appearance as a whole. The deep white matter showed high signals in the T2-weighted image. To our knowledge, the honey comb-like appearance has never been reported in this disorder. Deposition of mucopolysaccharides and/or glycolipids and increase in fluid content seem to be responsible for these changes.

    Serial neuroradiological studies in focal cerebritis (1994)

    Notes: Abstract We report serial neuroradiological studies in a patient with focal cerebritis in the head of the left caudate nucleus. On the day after the onset of symptoms, CT showed an ill-defined low density lesion. The lack of contrast enhancement appeared to be the most important finding for differentiating focal cerebritis from an encapsulated brain abscess or a tumour. MRI two days later revealed the centre of the lesion to be of slightly low intensity on T1-weighted inversion recovery (IR) images and very low intensity on T2-weighted spin echo images, which appeared to correspond to the early cerebritis stage of experimentally induced cerebritis and brain abscess. Ten days after the onset of symptoms, CT revealed a thin ring of enhancement in the head of the caudate nucleus, and a similar small ring was seen in the hypothalamus 16 days after the onset, corresponding to the late cerebritis stage. MRI nine days later revealed ill-defined high signal lesions within the involved area on the T1-weighted IR images. To our knowledge, this is the first published MRI documentation of the early cerebritis stage developing into an encapsulated brain abscess. The mechanisms underlying of these radiographic changes are discussed.
