16. Endovascular Repair of Abdominal Aortic Aneurysms. Aspects on a Novel Technique
Sammanfattning : A new concept of treating abdominal aortic aneurysms was studied during a three-year period. Instead of open repair, graft insertion was accomplished endovascularly from the groins. The graft was attached by expandable stents to the non-dilated infrarenal aorta, i.e. LÄS MER
17. Abdominal aortic aneurysm inception and evolution - A computational model
Sammanfattning : Abdominal aortic aneurysm (AAA) is characterized by a bulge in the abdominal aorta. AAA development is mostly asymptomatic, but such a bulge may suddenly rupture, which is associated with a high mortality rate. Unfortunately, there is no medication that can prevent AAA from expanding or rupturing. LÄS MER
18. Small-Animal Imaging with Liquid-Metal-Jet X-Ray Sources
Sammanfattning : Small-animal x-ray imaging is an important tool for medical research. The penetration power of x-rays makes it possible to investigate the 3D structure of small animals and other thick biological samples by computed tomography (CT). LÄS MER
19. Optimization of intravenous contrast media at computed tomography
Sammanfattning : The administration of intravenous contrast media (IV CM) is essential for detecting lesions at most computed tomography (CT) examinations. The overall aim of this thesis is to investigate different aspects of IV CM administration that may affect the quality of the CT examination. LÄS MER
20. Large cerebral artery occlusion and recanalisation in stroke patients treated with intravenous thrombolysis : clinical and radiological markers and their clinical relevance
Sammanfattning : Large cerebral artery occlusion accounts for 40-46% of ischemic strokes. These strokes are characterized by extensive neurological deficit, poor functional outcome, and increased mortality (up to 40-80% in the most severe clinical syndromes). LÄS MER
