1. Abdominal Aortic Aneurysm : Molecular Imaging Studies of Pathophysiology
Sammanfattning : The pathological process behind abdominal aortic aneurysm (AAA) formation is poorly understood and difficult to study. The aim of the thesis was to study the pathophysiology of AAA formation with positron emission tomography (PET) technology, a molecular imaging technique, allowing in vivo studies of pathophysiological changes.

3. [11C]Carbon Monoxide and Aryl Triflates in Palladium-Mediated Carbonylation Reactions : Synthetic approaches to [11C]Carbonyl Compounds and [11C]Amines
Sammanfattning : The usefulness of low concentrations (typically 10 to 100 µM) of [11C]carbon monoxide and aryl triflates as substrates in 11C-carbonylation using different nucleophiles in the presence of lithium bromide was investigated. The reactions were performed in a micro autoclave of 200 µL volume and catalysed (mediated) by palladium(0). LÄS MER
4. Markers of inflammation and neurodegeneration in muliple sclerosis
Sammanfattning : The main line of my thesis projects is searching for biomarkers and evidence of optimal correlation with clinical and para-clinical outcome measurements in multiple sclerosis (MS): investigating the biochemical biomarker in blood/plasma (cerebrosterol) and in cerebrospinal fluid (CSF) (oligoclonal bands (OCB)) and the correlation with MRI lesion load (paper 1 and paper IV); investigating the genetic biomarker (CYP46A1) for susceptibility and disability progression in MS (Paper III); comparison of the well-known positron emission tomography (PET) ligand and peripheral benzodiazepine receptor (PBR) antagonist, [11C]PK11195, and a new PET ligand [11C]vinpocetine (tissue receptor biomarker). Both ligands denote areas of active ongoing inflammation in MS (paper II). LÄS MER
5. 11C Molecular Imaging in Focal Epilepsy
Sammanfattning : 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. LÄS MER
