Journal ArticleDOI
Quantitative Brain Magnetic Resonance Imaging in Attention-Deficit Hyperactivity Disorder
F X Castellanos,Jay N. Giedd,W L Marsh,Susan D. Hamburger,A C Vaituzis,Daniel P. Dickstein,S E Sarfatti,Yolanda C. Vauss,John Snell,Nicholas Lange,Debra Kaysen,Amy L. Krain,G F Ritchie,Jagath C. Rajapakse,Judith L. Rapoport +14 more
TL;DR: This first comprehensive morphometric analysis is consistent with hypothesized dysfunction of right-sided prefrontal-striatal systems in ADHD.
Journal ArticleDOI
Cerebellum in attention-deficit hyperactivity disorder: a morphometric MRI study.
P. C. Berquin,Jay N. Giedd,L. K. Jacobsen,Susan D. Hamburger,Amy L. Krain,Judith L. Rapoport,F X Castellanos +6 more
TL;DR: A cerebello-thalamo-prefrontal circuit dysfunction may subserve the motor control, inhibition, and executive function deficits encountered in ADHD.
Journal ArticleDOI
Quantitative Morphology of the Cerebellum and Fourth Ventricle in Childhood-Onset Schizophrenia
Leslie K. Jacobsen,Jay N. Giedd,Patrick C. Berquin,Amy L. Krain,Susan D. Hamburger,Sanjiv Kumra,Judith L. Rapoport +6 more
TL;DR: Findings are consistent with observations of small vermal size in adult schizophrenia and provide further support for abnormal cerebellar function in childhood- and adult-onset schizophrenia.
Journal ArticleDOI
A technique for single-channel MR brain tissue segmentation: Application to a pediatric sample
Jagath C. Rajapakse,Jay N. Giedd,Charles DeCarli,John Snell,Alan C. McLaughlin,Yolanda C. Vauss,Amy L. Krain,Susan D. Hamburger,Judith L. Rapoport +8 more
TL;DR: Segmentation of MR brain scans of 105 healthy children and adolescents showed that although the total brain volume was stable over age 4-18, white matter increased and gray matter decreased significantly, and white matter volume increased the most in superior and posterior regions and laterality effects were seen in hemisphere tissue volumes.
Journal ArticleDOI
Cerebral magnetic resonance image segmentation using data fusion.
Jagath C. Rajapakse,Charles DeCarli,Alan C. McLaughlin,Jay N. Giedd,Amy L. Krain,Susan D. Hamburger,Judith L. Rapoport +6 more
TL;DR: This simple, reliable, and valid method can be employed in clinical research for quantification of gray and white matter and CSF volumes in MR head scans.
