1. Differentiation of Central Nervous System Tumors: Multiparametric magnetic resonance imaging with histological, genetic, and prognostic correlations
Sammanfattning : .... LÄS MER
2. Multiparametric MRI for evaluation of tumour treatment response : Studies of 177Lu-octreotate therapy of neuroendocrine tumour
Sammanfattning : Clinical assessment of tumour response to treatment largely relies on estimates of tumour size by, e.g., measuring the largest tumour diameters on magnetic resonance (MR) or computed tomography (CT) images, weeks or months after treatment. LÄS MER
3. Applications of statistical methods in quantitative magnetic resonance imaging
Sammanfattning : Magnetic resonance imaging, MRI, offers a vast range of imaging methods that can be employed in the characterization of tumors. MRI is generally used in a qualitative way, where radiologists interpret the images for e.g. diagnosis, follow ups, or assessment of treatment response. LÄS MER
4. The effect of mechanical ventilation on the abdominal organs
Sammanfattning : During mechanical ventilation (MV), the interplay between abdomen and thorax has been studied unilaterally focusing on the effect that an increased abdominal pressure would have on the thorax. Only a small cluster of studies offered a different perspective showing a lower inflammation and a better lymphatic clearance of edema in abdominal organs when spontaneous breathing was applied compared to MV.

5. Assessment of Myocardial Perfusion with Magnetic Resonance Imaging and an Intravascular Contrast Agent
Sammanfattning : The intravascular contrast agent NC100150 Injection (Clariscan™) was tested for its ability to induce signal intensity changes in myocardium, both in steady state and during first pass, and thereby demarcating non-perfused myocardium from perfused. Steady state: Ex vivo in pigs and when using 4 mg Fe/kg bodyweight (b.w. LÄS MER
