21. Technomedical Visions : Magnetic Resonance Imaging in 1980s Sweden
Abstract : The medical imaging technology called MRI (magnetic resonance imaging) stems from a blind measurement technology which was further developed in research and practice to enable seeing into the inner body. Vision with MRI was open-ended, and it was developed and tamed in a context of fragmented medical perspectives on the body and on technology. READ MORE

22. Advancements in DSC and BOLD perfusion imaging: Acquisition, analysis and clinical application
Abstract : This thesis is focused on perfusion MRI techniques and topics related to image acquisition, analysis and clinical applications. The first half of the thesis is focused on dynamic susceptibility contrast (DSC) MRI, a technique which is based on the contrast enhancements caused by an intravenously administered paramagnetic contrast agent.

23. Quantification of Fat Content and Fatty Acid Composition Using Magnetic Resonance Imaging
Abstract : In obesity and several other disease scenarios, the measurement of fat accumulation in various organs and tissues has become a sought-after technique in clinical diagnostics and research. Especially, quantitative and non-invasive techniques which also provide images of accumulated fat throughout the body would be valuable. READ MORE

24. Volumetric MRI measurements of velocity and flow - Accuracy, visualisation and technical improvements
Abstract : In the last two decades, phase-contrast magnetic resonance imaging (PC-MRI) has evolved from two-dimensional velocity and flow measurements to volumetric, time-resolved depictions of velocity fields (4D PC). The acquisition of time-resolved velocity fields allows flow visualisations that might provide better understanding of the dynamics of the cardiac system. READ MORE

25. Assessment of Renal Physiology Using Functional MRI
Abstract : Kidney injury is a major cause of morbidity and mortality throughout the world, leading to substantial individual suffering and to a heavy financial burden for the society. A large number of common conditions such as diabetes, hypertension, autoimmune diseases and infections are highly associated with kidney injury. READ MORE
