PURPOSE To prospectively compare gadolinium-enhanced magnetic resonance (MR) angiography and computed tomographic (CT) angiography with digital subtraction angiography (DSA) for use in detecting atheromatous stenosis and plaque morphology at the carotid bifurcation. MATERIALS AND METHODS Forty-four carotid arteries (in 22 patients) were analyzed by using(More)
OBJECTIVES To compare methods of measuring fetal pulmonary volume and to establish nomograms of fetal pulmonary volume according to gestational age for the accurate diagnosis of pulmonary hypoplasia. METHODS Three methods of measuring fetal pulmonary volume in 39 normal fetuses were compared: two-dimensional (2D) ultrasound measurement assuming that the(More)
A dot-filling test was used to assess hand performance in two populations of French children. In the first experiment, the effect of sex, age and handedness on hand performance was examined (1742 children). Age was related to the degree of laterality, but girls were less lateralized than boys. The second experiment (200 children) showed that the surprising(More)
PURPOSE To determine whether measurements of the volume of the hippocampal formation obtained from a three-dimensional acquisition not perpendicular to the hippocampus are statistically different from those obtained from a perpendicular acquisition. METHODS Both hippocampi were studied in 10 healthy volunteers with two three-dimensional acquisitions,(More)
OBJECTIVES Our purpose was to evaluate perinatal mortality in twins and to investigate factors associated with this mortality. STUDY DESIGN A prospective study on the perinatal mortality was performed in the department of Seine-Saint-Denis. Out of all the perinatal deaths, we have retrospectively isolated those arising from twin pregnancies. RESULTS(More)
This paper reports a selection of completed or ongoing studies that have evaluated or applied the Strengths and Difficulties Questionnaire (SDQ) in five countries of Southern Europe: Italy, Spain, Portugal, Croatia, and France. In Italy, the SDQ has been used to study its concurrent validity with other norm-based instruments (Child Behavior Checklist—CBCL(More)
There has been considerable interest in cognitive deficits associated with Alzheimer's disease (AD) and relationships between these impairments and specific cortical atrophies. Two previous studies [Neuropsychologia 28 (1990) 1197; Dementia 3 (1992) 350] have found that AD patients exhibit significant impairments in the attentional ID/ED set-shifting tasks(More)
Neuroimaging studies investigating the neural correlates of verbal fluency (VF) focused on sex differences without taking into account behavioural variation. Nevertheless, group differences in this verbal ability might account for neurocognitive differences elicited between men and women. The aim of this study was to test sex and performance level effects(More)
The aim of this research was to study the relationship between explicit memory and hippocampal volume. Seventy healthy adults were administered one implicit memory test and one explicit memory (EM) test and underwent magnetic resonance imaging. The major finding was a negative correlation between the EM test and the right hippocampus/brain volume ratio (t =(More)
MICHEL DUYME CNRS Analyses from an a priori full cross-fostering study (Capron & Duyme, 1989, 1991), investigating the IQs of 38 children whose average age was 168 (SE = 3.28) months, indicated a link between the socioeconomic status @ES) of both biological and adoptive parents and Full, Verbal, and Performance IQs of the WISC-R scale. Here detailed(More)
