16. Imaging Living Cells with an X-ray Laser
Sammanfattning : Imaging living cells at a resolution higher than the resolution of optical microscopy is a significant challenge. Fluorescence microscopy can achieve a degree of super-resolution via labeling cellular components with a fluorescent dye. LÄS MER
17. Proton Relaxation Properties of a Particulate Iron Oxide MR Contrast Agent in Different Tissue Systems : Implications for Imaging
Sammanfattning : Knowledge of the relationship between in vivo contrast agent concentration and magnetic resonance (MR) signal response is an important requirement in contrast enhanced MR imaging in general and in MR based perfusion imaging in particular. This relationship is a complex function of the properties of the contrast agent as well as the structure of the target tissue. LÄS MER
18. Differentiation of Central Nervous System Tumors: Multiparametric magnetic resonance imaging with histological, genetic, and prognostic correlations
Sammanfattning : .... LÄS MER
19. Optical and laser diagnostics : The versatility of Imaging
Sammanfattning : Optical and laser diagnostics is a field where optical techniques are developed that offer remote, non-intrusive measurements in order to characterise a system. Imaging is a big part of this field and the versatility it offers makes it a great tool in the hands of researchers and in practical applications. LÄS MER
20. Characterization of [18F]flutemetamol binding properties : A β-amyloid PET imaging ligand
Sammanfattning : The criteria for diagnosing Alzheimer’s disease (AD) have recently been revised to include the use of biomarkers for the in vivo presence of β-amyloid, one of the neuropathological hallmarks of AD. Examples of such biomarkers are positron emission tomography (PET) β-amyloid specific ligands, including [18F]flutemetamol. LÄS MER
