Assessment of ventricular size is essential in clinical management of hydrocephalus and other neurological disorders. At present, ventricular size is assessed using indices derived from the dimensions of the ventricles rather than the actual volumes. In a population of 22 children with congenital hydrocephalus and 22 controls, the authors evaluated the(More)
PURPOSE To examine acute alterations in white matter (WM) diffusion based on diffusion tensor imaging (DTI) in youth with mild traumatic brain injury (mTBI) relative to orthopedic injury (OI) controls. METHODS A prospective cohort study of 23 patients with mTBI and 20 OI controls ages 11-16 years were recruited from the emergency department (ED). DTI was(More)
Increased intracranial pressure and ventriculomegaly in children with hydrocephalus are known to have adverse effects on white matter structure. This study seeks to investigate the impact of hydrocephalus on topological features of brain networks in children. The goal was to investigate structural network connectivity, at both global and regional levels, in(More)
Treatments for pediatric obsessive-compulsive disorder (OCD) could be enhanced if the physiological changes engendered by treatment were known. This study examined neural correlates of a provocation task in youth with OCD, before and after sham-controlled repetitive transcranial magnetic stimulation (rTMS). We hypothesized that rTMS to the right(More)
Neuroimaging research in surgically treated pediatric hydrocephalus patients remains challenging due to the artifact caused by programmable shunt. Our previous study has demonstrated significant alterations in the whole brain white matter structural connectivity based on diffusion tensor imaging (DTI) and graph theoretical analysis in children with(More)
