2. 1. Multimodal Imaging of Anisotropic Hierarchical Materials

   Author : Adrian Rodriguez Palomo; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Biomaterials; Hierarchical Materials; Multimodal Imaging; Birefringence; X-Ray Scattering;

   Abstract : The thesis is focused on studying the nanostructure of natural and synthetic hierarchical materials with biological applications, using X-ray scattering imaging and birefringence microscopy. The term "hierarchical materials" is used for structures composed of sub-units organised in different length scales that create the building blocks for the next level. READ MORE

4. 2. Decoding the complex brain : multivariate and multimodal analyses of neuroimaging data

   Author : Alireza Salami; Lars Nyberg; Cheryl Grady; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multivariate analysis; univariate analysis; multimodal imaging; episodic memory; aging; functional magnetic resonance imaging; diffusion tensor imaging; biology; biologi; Psychology; psykologi; datoriserad bildanalys; Computerized Image Analysis;

   Abstract : Functional brain images are extraordinarily rich data sets that reveal distributed brain networks engaged in a wide variety of cognitive operations. It is a substantial challenge both to create models of cognition that mimic behavior and underlying cognitive processes and to choose a suitable analytic method to identify underlying brain networks.

   Abstract : Diagnostic ultrasound (US) is safer, quicker and cheaper than other diagnostic imaging modalities. Over the past two decades, the applications of US imaging has been widened due to the development of injectable, compressible and encapsulated microbubbles (MBs) that provide an opportunity to improve conventional echocardiographic imaging, blood flow assessment and molecular imaging.

6. 4. Multimodal Chemical Imaging of Amyloid Plaque Pathology in Alzheimer’s Disease

   Author : Wojciech Michno; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alzheimer’s disease; beta-amyloid; electron microscopy; imaging mass spectrometry; lipids; luminescent conjugated oligothiophenes; matrix-assisted laser desorption ionization mass spectrometry MALDI-MS ; molecular imaging; nanoscale secondary ion mass spectrometry NanoSIMS ; neurodegeneration; peptides;

   Abstract : Alzheimer’s disease (AD) is the most common form of dementia. AD has been linked to the aggregation of amyloid beta (Aβ) peptides into extracellular deposits, Aβ plaques. These are also found in cognitively unimpaired amyloid-positive (CU-AP) individuals, but these Aβ plaques are primarily diffuse in structure. READ MORE

7. 5. Non-Invasive Characterization of Liver Disease : By Multimodal Quantitative Magnetic Resonance

   Author : Markus Karlsson; Peter Lundberg; Gunnar Cedersund; Nils Dahlström; Stergios Kechagias; Steven Sourbron; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : There is a large and unmet need for diagnostic tool that can be used to characterize chronic liver diseases (CLD). In the earlier stages of CLD, much of the diagnostics involves performing biopsies, which are evaluated by a histopathologist for the presence of e.g. fat, iron, inflammation, and fibrosis. READ MORE
