OBJECTIVE This study, part of a continuing effort to understand the pathophysiology of the brain in early-onset anorexia nervosa, attempts to validate findings from an earlier study of regional cerebral blood flow and to correlate any abnormalities in blood flow with eating disorder psychopathology. METHOD Fifteen newly referred children and adolescents(More)
The reported abnormalities of brain function in anorexia nervosa (AN) include impairment of neural circuits involving cortical (orbito-frontal, somatosensory and parietal) and sub-cortical (amygdala, hippocampus, thalamus, hypothalamus and striatum) structures. The insular cortex serves an integrative function for all the structures relevant to the features(More)
The purpose of this guideline is to offer to the nuclear medicine team a framework, which could prove helpful in daily practice. This guideline contains information related to the procedure and indications of measurement of glomerular filtration rate using blood samples in children. The present document is inspired by the report of the Radionuclides in(More)
Special consideration needs to be given to children who undergo dynamic renography. The Paediatric Committee of the European Association of Nuclear Medicine has updated the previous guidelines. Details are provided on how to manage the child, the equipment, and the acquisition and processing protocols. The pitfalls, difficulties and controversies that are(More)
OBJECT Arterial spin labelling (ASL) can be used to measure renal perfusion non-invasively. The aim of this study was to determine the repeatability of this technique in healthy kidneys to vindicate its use in clinic. MATERIALS AND METHODS Two groups of healthy volunteers were imaged two different days to assess intra- and inter-session repeatability.(More)
PURPOSE This study assessed test-retest reliability and repeatability of diffusion tensor imaging (DTI) in the kidneys. MATERIALS AND METHODS Seven healthy volunteers (age range, 19-31 years), were imaged three consecutive times on the same day (short-term reliability) and the same imaging protocol was repeated after a month (long-term reliability).(More)
Previous neuroimaging studies in early-onset anorexia nervosa provide evidence of limbic system dysfunction. The current study adds support to the possibility by revealing a significant association between unilateral reduction of blood flow in the temporal region and impaired visuospatial ability, impaired visual memory, and enhanced speed of information(More)
These guidelines on the use of radioiodinated (99m)Tc-MIBG scintigraphy in children, which summarise the views of the Paediatric Committee of the European Association of Nuclear Medicine, provide a framework which may prove helpful to nuclear medicine teams in daily practice. They have been influenced by the conclusions of the "Consensus Guidelines for MIBG(More)
PURPOSE The aim of this study was to investigate the maximum height, area under the curve (AUC) and full width at half maximum (FWHM) of the aortic input function (AIF) in renal dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) studies. We evaluated the significance of choice of size for regions of interest (ROI) in the aorta, reproducibility(More)

Radioisotope brain imaging has focused mainly on regional cerebral blood flow (rCBF). However the use of ligands which go to specific receptor sites is being introduced in paediatrics, mainly psychiatry. rCBF is potentially available in many institutions, especially with the availability of multi-headed gamma cameras. The use of this technique in(More)
