6. Development and evaluation of non-invasive ultrasonic methods for arterial characterization
Sammanfattning : As cardiovascular diseases have been the most common cause of mortality in the western world for decades, the demand for appropriate diagnostic methods is obvious. To facilitate the examination non-invasive methods are preferable since they do not require sensors within the circulation system. LÄS MER
7. The Non-Invasive Brain Biopsy : Implementation and Application of Quantitative Magnetic Resonance Spectroscopy on Healthy and Diseased Human Brain
Sammanfattning : Introduction: In this thesis, one of the major objectives was to implement a method for (absolute) quantitative magnetic resonance spectroscopy (qMRS) of the human brain, intended for clinical use. The implemented method was based on standard spatially selective MRS sequences. LÄS MER
8. Non-Invasive Characterization of Liver Disease : By Multimodal Quantitative Magnetic Resonance
Sammanfattning : 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. LÄS MER
9. Non-invasive Functional Neuroimaging for Localizing Epileptic Brain Activity
Sammanfattning : Surgical therapy has become an important therapeutic alternative for patients with medically intractable epilepsy. Correct and anatomically precise localization of the epileptic focus, preferably with non-invasive methods, is the main goal of the pre-surgical epilepsy diagnosis to decide if resection of brain tissue is possible.

10. Non-Invasive Measures of Heart Failure
Sammanfattning : Heart failure is a clinical syndrome characterized by an inability of the heart to meet the metabolic demands of the body. Approximately 1-2% of the population in the western society has the diagnosis, and the 5-year mortality rate is comparable with the common cancer diagnoses. LÄS MER
