1. 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
2. Methodological aspects of quantitative cardiac molecular imaging
Sammanfattning : The objective of this research was to facilitate the use of quantitative cardiac molecular imaging by developing and validating methods and applications. More specifically:we determined the optimal tracer kinetic model for analysis of 11C-PIB and evaluated the performance of two simpler measures, retention index (RI) and standardized uptake value (SUV), in the quantification of cardiac 11C-PIB uptake in amyloidosis.

3. On potentials and limitations of perfusion MRI in neurological disorders
Sammanfattning : Cerebral perfusion outlines several parameters which describe the status of cerebral haemodynamics. Numerous neurological diseases affect cerebral perfusion, thus the importance of diagnostic measurements. LÄS MER
4. Positron Emission Tomography (PET) Studies in Anxiety Disorders
Sammanfattning : Anxiety disorders are very common and the primary feature is abnormal or inappropriate anxiety. Fear and anxiety is often mediated by the amygdala, a brain structure rich in substance P (SP) and neurokinin 1 (NK1) receptors. LÄS MER
5. PET in Heart Failure - Methods and Applications
Sammanfattning : Positron Emission Tomography (PET) permits regional myocardial perfusion, fibrosis and oxidative metabolism to be non-invasively quantified with radioactive tracers such as [15O]-water and [1-11C]-acetate. PET is an established research tool in congestive heart failure (CHF), a major cause of morbidity and mortality. LÄS MER
