16. Preclinical Molecular Imaging using Multi-Isotope Digital Autoradiography - Techniques and Applications
Sammanfattning : Molecular imaging, both in vivo and ex vivo, is playing an increasingly important role in preclinical medical research. When using radionuclide-labeled tracers, e.g. in the development of radiopharmaceuticals for diagnostic imaging or for radionuclide therapy, quantitative in vivo imaging can be performed using emission tomography.

17. Diffusion tensor magnetic resonance imaging of the brain : Tractography analysis with application in healthy individuals and patients
Sammanfattning : In study 1, thirty-eight healthy controls were used for optimization of the method. Fifteen patients with progressive supranuclear palsy and an equal number of age-matched healthy controls underwent diffusion tensor MRI and were then investigated and compared groupwise. LÄS MER
18. Quantitative methods for tumor imaging with dynamic PET
Sammanfattning : 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. LÄS MER
19. Contributions to quantitative dynamic contrast-enhanced MRI
Sammanfattning : Background: Dynamic contrast-enhanced MRI (DCE-MRI) has the potential to produce images of physiological quantities such as blood flow, blood vessel volume fraction, and blood vessel permeability. Such information is highly valuable, e.g., in oncology. LÄS MER
20. New perspectives on imaging of urinary tract infections in infants
Sammanfattning : Background: Urinary tract infection (UTI) is a common disease in infants that may lead to renal damage with an increased risk of long term complications. The diagnostic imaging aims to identify risk factors as underlying urinary tract abnormalities and renal involvement of the infection for prevention of long term adverse outcome. LÄS MER
