2. 1. Waiting time and mortality in coronary artery bypass grafting patients

   Author : Helena Rexius; Göteborgs universitet; []
   Keywords : coronary artery bypass grafting; waiting time; mortality; gender; risk score;

   Abstract : Coronary Artery Bypass Grafting (CABG) has emerged as one of the most common major surgical procedures worldwide. Unfortunately the capacity is still unable to meet the demand in many countries. This leads to waiting times before surgery, prioritisation between patients and ultimately to deaths among the patients on the waiting list.Aims: 1. READ MORE

4. 2. Vessel occlusion and functional outcome after acute stroke : prediction and evaluation

   Author : Charith Cooray; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : In the acute setting of ischaemic stroke, two proven treatments are available: intravenous thrombolysis (iv-tPA) with alteplase and endovascular thrombectomy. The main aim of this thesis was to investigate the associations between symptom severity in the acute setting of ischaemic stroke and 1) the presence of arterial occlusions and 2) long-term functional outcome assessed at 3 months.

5. 3. Cerebral arterial pulsatility imaging using 4D flow MRI : methodological development and applications in brain aging

   Author : Tomas Vikner; Anders Wåhlin; Anders Eklund; Jan Malm; Lars Nyberg; Susanne Schnell; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; 4D flow MRI; medical image analysis; cerebral hemodynamics; arterial pulsatility; DCE MRI; blood-brain barrier; white matter lesions; perivascular spaces; cerebral small vessel disease; hippocampus; cognition; aging; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

   Abstract : 4D flow magnetic resonance imaging (MRI) is increasingly recognizedas a versatile tool to assess arterial and venous hemodynamics. Cerebral arterial pulsatility is typically assessed by analyzing flow waveforms over the cardiac cycle, where flow amplitude is a function of cardiac output, central arterial stiffness, and cerebrovascular resistance and compliance.

6. 4. Assessment of Atherosclerosis by Whole-Body Magnetic Resonance Angiography

   Author : Tomas Hansen; Håkan Ahlström; Lars Lind; Johan Wikström; Lars Johansson; Björn Fagerberg; Uppsala universitet; []
   Keywords : Radiology; Atherosclerosis; Magnetic Resonance Angiography; Epidemiology; Radiologisk forskning;

   Abstract : Atherosclerosis is a serious threat to public health and a major cause of morbidity and mortality. In this doctoral research, the feasibility of using whole-body magnetic resonance angiography (WBMRA) was studied as a principal aim both in patients and in an epidemiological setting. READ MORE

7. 5. Longitudinal Common Carotid Artery Wall Motion - mechanistic, prognostic and translational studies

   Author : Sara Svedlund; Göteborgs universitet; []
   Keywords : carotid artery; longitudinal wall motion; ultrasound; velocity vector imaging; risk factor;

   Abstract : The longitudinal arterial movement of the common carotid artery (CCA) has been less investigated during the past compared to the radial movement. This is probably due to lack of an adequate measuring method. Velocity vector ultrasound imaging (VVI) now enables assessment of the longitudinal movement. READ MORE
