  1. 1. Quantitative methods for tumor imaging with dynamic PET

    University dissertation from Umeå : Umeå Universitet

    Author : Ida Häggström; Umeå universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Dynamic positron emission tomography; PET; tumor imaging; compartment modeling; Monte Carlo; radiofysik; radiofysik;

    Abstract : There is always a need and drive to improve modern cancer care. Dynamic positron emission tomography (PET) offers the advantage of in vivo functional imaging, combined with the ability to follow the physiological processes over time. READ MORE

  2. 2. Blood-Brain Barrier Transport Investigation of Active Efflux using Positron Emission Tomography and Modelling Studies

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Stina Syvänen; Uppsala universitet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical biosciences; pharmacokinetics; P-glycoprotein; blood-brain barrier; modelling; PET; active efflux; species differences; [11C]verapamil; drug development; Farmaceutisk biovetenskap;

    Abstract : This thesis examines the transport of exogenous molecules across the blood-brain barrier (BBB), focusing on active efflux, using positron emission tomography (PET), computer simulation and modelling. P-glycoprotein (P-gp) inhibition was studied using [11C]verapamil and [11C]hydroxyurea was investigated as a new marker for active efflux transport. READ MORE

  3. 3. Regional Lung Kinetics of Ventilator-Induced Lung Injury and Protective-Ventilation Strategies Studied by Dynamic Positron Emission Tomography

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : João Batista Borges; Uppsala universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; [18F]fluoro-2-deoxy-D-glucose; positron emission tomography; acute pulmonary inflammation; acute respiratory distress syndrome; mechanical ventilation; ventilator-induced lung injury;

    Abstract : Mechanical ventilation in itself can harm the lung and cause ventilator-induced lung injury (VILI), which can induce or aggravate acute respiratory distress syndrome (ARDS). Much debate remains over pivotal concepts regarding the pathophysiology of VILI, especially about the precise contribution, kinetics, and primary role of potential VILI mechanisms. READ MORE

  4. 4. Amyloid imaging in Alzheimer´s disease and mild cognitive impairment by Positron Emission Tomography

    University dissertation from Stockholm : Karolinska Institutet, Department of Neurobiology, Care Sciences and Society

    Author : Anton Forsberg; Karolinska Institutet.; Karolinska Institutet.; [2008]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Effectiveness of future treatment strategies in Alzheimer s disease (AD) will rely on early detection of disease and the possibility to clearly evaluate their effects. The findings presented in this thesis concerns both early in vivo detection of amyloid deposition in the brains of patients at risk of developing AD and the longitudinal changes of pathological and functional parameters in patients with AD.

  5. 5. 11C Molecular Imaging in Focal Epilepsy

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Torsten Danfors; Uppsala universitet.; Uppsala universitet.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; positron emission tomography; methionine; NK1; substance p; flumazenil; deprenyl; pk11195; phosphoimager; autoradiography; TBI; traumatic brain injury; iron chloride; ferrous chloride; Neurology; Neurologi; Radiology; Radiologi;

    Abstract : Epilepsy is a common neurological disease affecting 6 million people in Europe. Early prevention and accurate diagnosis and treatment are of importance to obtain seizure freedom. In this thesis new applications of carbon-11-labelled tracers in PET and autoradiographic studies were explored in focal epilepsy. READ MORE
