11. [18F]Flutemetamol PET image processing, visualization and quantification targeting clinical routine
Sammanfattning : Alzheimer’s disease (AD) is the leading cause of dementia and is alone responsible for 60-70% of all cases of dementia. Though sharing clinical symptoms with other types of dementia, the hallmarks of AD are the abundance of extracellular depositions of β-amyloid (Aβ) plaques, intracellular neurofibrillary tangles of hyper phosphorylated tau proteins and synaptic depletion.

12. Evaluation of Regularized Image Reconstruction for Clinical Positron Emission Tomography
Sammanfattning : Positron emission tomography (PET) combined with computed tomography (CT) is a widely used noninvasive molecular imaging modality with a broad range of clinical applications in oncology, neurology, and cardiology. Producing imperative image quality and accurate quantification are important driving forces behind the technological advances within PET image reconstruction and system development. LÄS MER
13. Quantitative cardiac 15O-water PET : Assessment of left-ventricular function, remodeling, and impact of patient motion
Sammanfattning : International guidelines advocate the use of noninvasive cardiac imaging as the initial diagnostic test for coronary artery disease, the global leading cause of death according to the world health organization. Within the wide spectrum of cardiac imaging, 15O-water PET is the gold standard for noninvasive quantification of myocardial blood flow (MBF). LÄS MER
14. PET in Prostate Cancer – Detection, Tumour Biology and Prognosis
Sammanfattning : Prostate cancer (PCa) is the most common non-cutaneous malignancy in men and the leading cause of cancer-related deaths in Sweden. Despite the major advances, the current diagnostic modalities fall short of standards, specifically, precise localization required for effective management of the PCa. LÄS MER
15. Dosimetry of Radionuclide Therapy with 177Lu-octreotate
Sammanfattning : In radionuclide therapy it is still common to administer standard activities or to scale administered activity with blunt parameters such as body weight or surface area. This is not ideal because, due to considerable variation in kinetics, large safety margins have to be applied to avoid radiation damage to healthy organs, which causes under-treatment of many patients.
