1. 11. Advancements of 2D speckle tracking of arterial wall movements

   Författare :John Albinsson; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultraljud; block-matching; vävnadsrörelser; longitudinal movement;

   Sammanfattning : Cardiovascular diseases are the leading cause of death worldwide. In order to improve the diagnostics and facilitate early interventions of cardiovascular diseases, knowledge about the physiology of the vascular system in both healthy subjects and in subjects with vascular disease is needed.

3. 12. Arterial wall stiffness in man. On gender differences and abnormalities in insulin dependent diabetes mellitus and alpha1-antitrypsin deficiency

   Författare :Åsa Rydén Ahlgren; Malmö Klinisk fysiologi och nuklearmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sex characteristics.; abdominal aortic aneurysm; arterial stiffness; alpha1-antitrypsin deficiency; ultrasonography; Insulin dependent diabetes mellitus; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

   Sammanfattning : The mechanical properties of major arteries may reflect early manifestations of vascular disease and are also of interest because they are important for cardiac work. Using echo-tracking sonography and blood pressure measurements, arterial stiffness and diameters were investigated in healthy individuals as well as in patients with insulin dependent diabetes mellitus (IDDM) or alpha1-antitrypsin deficiency (alpha1-AT deficiency).

4. 13. Turbulence Descriptors in Arterial Flows : Patient-Specific Computational Hemodynamics

   Författare :Magnus Andersson; Matts Karlsson; Jonas Lantz; Tino Ebbers; Kristian Valen-Sendstad; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : At this very moment, there are literally millions of people who suffer from various types of cardiovascular diseases (CVDs), many of whom will experience reduced quality of life or premature lift expectancy. The detailed underlying pathogenic processes behind many of these disorders are not well understood, but were abnormal dynamics of the blood flow (hemodynamics) are believed to play an important role, especially atypical flow-mediated frictional forces on the intraluminal wall (i.

5. 14. Aspects on arterial dimensions with special reference to aneurysmal disease

   Författare :Thomas Sandgren; Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; orthopaedics; Surgery; Arteria poplitea; Arteria femoralis; Aneurysm; Arterial dimensions; traumatology; Kirurgi; ortopedi; traumatologi;

   Sammanfattning : The incidence of abdominal aortic aneurysms (AAA) is increasing. The risk of rupture is related to diameter. However, rupture may occur also in small AAA. To evaluate the size of an aneurysm when related to the predicted normal aortic diameter might be a better predictor of risk. LÄS MER

7. 15. Development and evaluation of non-invasive ultrasonic methods for arterial characterization

   Författare :Anders Eriksson; Avdelningen för Biomedicinsk teknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Instrumentation technology; TDI; Tissue Doppler imaging; Arterial characterization; Non-invasive; Flow generation; PWV; Pulse wave velocity; Mät- och instrumenteringsteknik; Ultrasound; Vascular impedance;

   Sammanfattning : As cardiovascular diseases have been the most common cause of mortality in the western world for decades, the demand for appropriate diagnostic methods is obvious. To facilitate the examination non-invasive methods are preferable since they do not require sensors within the circulation system. LÄS MER
