Image quality and dose in computerized tomography: evaluation of four CT scanners.

Spatial resolution, statistical noise, and patient dose are important parameters for the evaluation of the performances of computerized tomography (CT) scanners. These parameters are combined to develop some "synthetic indices," and to be able to describe intrinsic properties of a CT scanner (the maximum obtainable spatial resolution and dose efficiency). This type of analysis has been applied to the evaluation of four CT scanners, three of third, and one of fourth generation.

[Learning disturbances in developmental ages. Consideration of some clinical cases studied with a neuropsychiatric approach].

The psychoanalytic and neuropsychiatric literature on learning disturbances has been reviewed. Relations between learning disturbances, psycho-affective, cognitive and neurological development are examined. Particular attention is paid to Klein's theory of intellectual inhibition and the integrative approach described by Rothstein. Four clinical cases, which seem to exemplify the infantile neuropsychiatric integrative approach are then presented. Finally, stress is laid on the pathogenetic interrelations between psychopathological and organic aspects of the children considered and the similarities between learning disturbances and pseudo mental deficiency.
