Recent progress in functional neuroimaging research has provided the opportunity to probe at the brain's intrinsic functional architecture. Synchronized spontaneous neuronal activity is present in the form of resting-state networks in the brain even in the absence of external stimuli. The objective of this study was to investigate the presence of(More)
Primary brain tumors with prominent desmoplasia include the gliofibroma, desmoplastic infantile ganglioglioma (DIG), pleomorphic xanthoastrocytoma (PXA), and desmoplastic cerebral astrocytoma. In the present report, we describe unusual pathological appearances in two successive resections of a left temporal tumor in a patient with complex partial seizures.(More)
Ten patients with findings at computed tomography (CT) suggesting intracranial supratentorial glioma were investigated to compare the diagnostic efficacy of this technique with that of positron emission tomography (PET) using 11C-methionine and examinations with magnetic resonance (MR). The findings were related to histopathologic examination of serial(More)
Five patients with glioma were examined with positron emission tomography using ([11C]methyl)-L-methionine. The study was repeated while the patient was being infused with branched chain amino acids (BCAA), 250 mumol/min. The accumulation rates of methionine in tumor tissue and in normal brain tissue were compared without and with the infusion of amino(More)
OBJECTIVE To examine associations between brain white matter abnormalities, including diffuse excessive high signal intensities, detected on neonatal magnetic resonance imaging (MRI) with neurodevelopmental outcome at age 30 months. STUDY DESIGN This was a prospective, population-based study of infants born at <27 weeks gestation (n=117) undergoing(More)
AIM To investigate cerebral white matter (WM) abnormalities (J Pediatr 2003; 143: 171) and diffuse and excessive high signal intensities (DEHSI), (J Pediatr 1999; 135: 351) in a cohort of extremely preterm infants born in Stockholm during a 3-year period, using magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI). METHODS MRI at(More)
Neonatal herpes simplex virus infection with involvement of the central nervous system is a serious disease with high morbidity, even with acyclovir therapy. The disability includes cerebral palsy and different aspects of cognitive dysfunction which are of utmost importance for the child's future habilitation. We conducted a descriptive cohort study to(More)
PURPOSE To describe a child with Muscle-Eye-Brain disease (MEB), one of three types of congenital muscular dystrophy associated with ocular abnormalities. METHODS Case report. RESULTS The child showed severe visual impairment due to progressive myopia and retinal degeneration, a pachygyria-type of migration disorder of the brain with a nodular cortical(More)
Disruption of the blood brain barrier or rather blood tumour barrier in cerebral tumours was studied with CT after intravenous injection of contrast medium and with PET after intravenous administration of 68-Ga-EDTA. Histology from stereotactic biopsies or open surgery is compared with the radiologic findings and advantages of the respective methods are(More)
Sixteen patients with supratentorial tumors were examined with positron emission tomography (PET) using [( 11C]methyl)-L-methionine, [11C]D-glucose, and [68Ga]EDTA as well as CT. There were nine astrocytomas (grade II), three oligoastrocytomas (grade II), two anaplastic astrocytomas (grade III), and two meningiomas. Six patients with low-grade astrocytomas(More)
