2. 21. Fast Methods for Vascular Segmentation Based on Approximate Skeleton Detection

   Author : Kristína Lidayová; Hans Frimmel; Ewert Bengtsson; Örjan Smedby; Alejandro F. Frangi; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical image analysis; automatic skeleton extraction; vascular segmentation; coverage segmentation; convolutional neural network classifier; CT angiography; Computerized Image Processing; Datoriserad bildbehandling;

   Abstract : Modern medical imaging techniques have revolutionized health care over the last decades, providing clinicians with high-resolution 3D images of the inside of the patient's body without the need for invasive procedures. Detailed images of the vascular anatomy can be captured by angiography, providing a valuable source of information when deciding whether a vascular intervention is needed, for planning treatment, and for analyzing the success of therapy.

4. 22. Tomographic methods in endovascular aortoiliac treatment

   Author : Per Törnqvist; Vaskulära sjukdomar - kliniska studier; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Endovascular treatment had developed rapidly and the procedures have increased in complexity. The demand of imaging excellence is imperative to perform these interventions. However both pre and postoperative investigations are performed by the use of advanced three-dimensional imaging, while the treatment itself relies on two-dimensional imaging. READ MORE

5. 23. Abdominal aortic aneurysm inception and evolution - A computational model

   Author : Andrii Grytsan; T. Christian Gasser; Martin Kroon; Frans N. van de Vosse; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aorta; Aneurysm; AAA; Blood Flow; Wall Shear Stress; Growth and Remodeling; Mixture Model; Growth Kinematics; Fluid-Solid-Growth; Aorta; Aneurysm; AAA; Blodflöde; Vägg Skjuvspänning; Tillväxt och Strukturförändring; Blandning Modell; Tillväxt Kinematik; Engineering Mechanics; Teknisk mekanik;

   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

6. 24. Noninvasive evaluation of the effects of coronary artery bypass grafting on myocardial function

   Author : Anders Hedman; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Coronary artery bypass grafting; C-reactive protein; dobutamine stress test; Doppler tissue imaging; echocardiography; exercise test; interleukin-6; myocardial peifusion scintigraphy.;

   Abstract : Coronary bypass grafting (CABG) is an effective treatment of patients with coronary artery disease and leads to an improvement in both cardiac symptoms and long-term survival. The effects of CA13G on global left ventricular systolic and diastolic function at rest and during stress, and the long-term effects on right ventricular function and their significance and relation to early graft occlusion and residual myocardial ischemia have however not been fully elucidated.

7. 25. Vasomotor Symptoms, Cardiovascular Risk and the Role of Physical Activity in Midlife Women

   Author : Sigrid Nilsson; Anna-Clara Spetz Holm; Wei Li; Karin Leander; Sofia Sederholm Lawesson; Peter Nilsson; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Background: The menopausal transition is, for most women, accompanied by hot flushes and night sweats (i.e., vasomotor symptoms, VMS). READ MORE
