1. Restructuring the socially anxious brain : Using magnetic resonance imaging to advance our understanding of effective cognitive behaviour therapy for social anxiety disorder
Sammanfattning : Social anxiety disorder (SAD) is a common psychiatric disorder associated with considerable suffering. Cognitive behaviour therapy (CBT) has been shown to be effective but a significant proportion does not respond or relapses, stressing the need of augmenting treatment. LÄS MER
2. Methods for the analysis and characterization of brain morphology from MRI images
Sammanfattning : Brain magnetic resonance imaging (MRI) is an imaging modality that produces detailed images of the brain without using any ionizing radiation. From a structural MRI scan, it is possible to extract morphological properties of different brain regions, such as their volume and shape. LÄS MER
3. Development and application of rule- and learning-based approaches within the scope of neuroimaging : Tensor voting, tractography and machine learning
Sammanfattning : The opportunity to non-invasively probe the structure and function of different parts of the human body makes medical imaging an indispensable tool in clinical diagnostics and related fields of research. Especially neuroscientists rely on modalities like structural or functional Magnetic Resonance Imaging, Computed Tomography or Positron Emission Tomography to study the human brain in vivo. LÄS MER
4. Gadodiamide injection for Enhancement of MRI in the CNS. Applications, dose, field and time dependence
Sammanfattning : Aims of the study The aims of this study using Gadodiamide injection were to investigate: · Whether Gadodiamide injection was comparable to Gd-DTPA for the enhancement of CNS lesions. · The contrast effect at different field strengths. · The effective time-window for the enhancement of blood-brain barrier damage.

5. Gradient echo-based quantitative MRI of human brain at 7T : Mapping of T1, MT saturation and local flip angle
Sammanfattning : Quantitative MRI (qMRI) refers to the process of deriving maps of MR contrast parameters, such as relaxation times, from conventional images. If the qMRI maps have a high degree of precision and a low degree of bias, they can be compared longitudinally, across subjects, and (ideally) between measurement protocols and research sites. LÄS MER
