  2. 16. Studies of cerebral blood flow and cerebrospinal fluid in childhood acute lymphoblastic leukemia

    Author : Gustaf Österlundh; Göteborgs universitet; []
    Keywords : childhood acute lymphoblastic leukemia; methotrexate; neurotoxicity; cerebral blood flow; single photon emission computed tomography; cerebrospinal fluid; neuron-specific enolase; glia fibrillary acidic protein; neurofilament; ascorbyl radical;

    Abstract : Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy and more than 80% of the patients are cured today. Treatment might cause side effects and central nervous system (CNS) irradiation has been replaced by systemic high-dose methotrexate (MTX) and intrathecal (IT) MTX due to the risk of late effects.

  4. 17. Social Phobia. From Epidemiology to Brain Function

    Author : Tomas Furmark; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Anxiety; brain; epidemiology; fear; neuroimaging; neurotransmitters; positron emission tomography; prevalence; serotonin; social phobia; subtypes; treatment; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : Social phobia is a disabling anxiety disorder characterized by an excessive fear of negative evaluation in social situations. The present thesis explored the epidemiology and neurobiology of the disorder. By means of a mailed questionnaire, the point prevalence of social phobia in the Swedish general population was estimated at 15.6%. READ MORE

  5. 18. Autism spectrum disorder in adults : biological dimensions

    Author : Irina Manouilenko; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Autism Spectrum Disorder (ASD) is a group of neurodevelopmental conditions characterized by difficulties in social interaction, communication and the presence of repetitive or stereotyped behaviors. Previous studies have demonstrated structural and functional abnormalities in different brain regions in ASD. READ MORE

  6. 19. Advances in brain SPECT : methodological and human investigations

    Author : Marco Pagani; Karolinska Institutet; Karolinska Institutet; []
    Keywords : SPECT; 99Tcm-HMPAO; Computerised Brain Atlas; rC13F; Control Subjects; Alzheimer s Disease; Frontal Lobe Dementia;

    Abstract : The aim of this work was to optimise and validate a new approach for examination of die regional cerebral blood flow (rCBF) using Single Photon Emission Computed Tomography (SPECT) for application in clinical research and patient care. It also involved the implementation of a software system for evaluation and analysis of rCBF. READ MORE

  7. 20. Evaluation of attenuation and scatter corrections in lung and brain SPECT

    Author : Agnetha Gustafsson; Bertil Axelsson; Göteborgs universitet Avdelningen för radiofysik Department of Radiations Physics; []
    Keywords : SPECT; attenuation; scatter; detectability; Monte Carlo simulation; MEDICINE; MEDICIN;

    Abstract : Single Photon Emission Computed Tomography (SPECT) is used to image functional processes in the human body. The image process is affected by physical effects such as attenuation, scatter, spatial resolution and statistical noise. READ MORE
