2. 1. Volume imaging of the abdomen : three-dimensional visualisation of tubular structures in the body with CT and MRI

   Author : Anders Persson; Örjan Smedby; Håkan Ahlström; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : The overwhelming amount of image-based information in modem medicine makes it crucial to develop methods to handle and analyze images and make them comprehensible for users. The aim of this thesis was to study the radiological practice of three-dimensional (3D) visualization of tubular structures in the body with CT and MRI. READ MORE

4. 2. Aspects on Imaging and Endovascular Treatment of Aortic Dissection and Aneurysm

   Author : Mats-Ola Eriksson; Rickard Nyman; Anders Wanhainen; Johnny Steuer; Mårten Falkenberg; Uppsala universitet; []
   Keywords : Aneurysms; aorta; stents; ultrasound; colour Doppler; vascular; interventional; aortic dissection; complicated; TEVAR; EVAR; re-intervention; survival; thrombosis; false lumen; aortic remodelling; Radiology; Radiologi;

   Abstract : Aortic aneurysm and dissections are potentially life threatening conditions. The advent of endovascular aortic repair (EVAR) and thoracic endovascular aortic repair (TEVAR) has reduced perioperative mortality and morbidity and are now established therapy methods for treatment of aortic disease.

   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; tomography; radiology; Clinical physics; Contrast media complications; Cost analysis; MR velocity mapping; Artefacts; MR imaging safety; MR angiography; MR imaging; Endovascular repair; Stent-graft; aortic; Aneurysm;

   Abstract : The aim of this study was to evaluate MRI with contrast enhanced MR angiography (MRI/CE MRA) as imaging method before and after endovascular repair of abdominal aortic aneurysms (AAA). A 1.5 T scanner was used for all examinations. In this prospective study 26 consecutive patients were included. READ MORE

6. 4. Abdominal aortic aneurysm inception and evolution - A computational model

   Author : Andrii Grytsan; T. Christian Gasser; Martin Kroon; Frans N. van de Vosse; KTH; []

   Abstract : 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. READ MORE

7. 5. Optimization of intravenous contrast media at computed tomography

   Author : Anders Svensson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : 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. READ MORE
