   Sammanfattning : Throughout the last century, medical imaging has come to revolutionise the way we diagnose disease, and is today an indispensable part of virtually any clinical practice. In cardiovascular care imaging is extensively utilised, and the development of novel techniques promises refined diagnostic abilities: ultrasound elastography allows for constitutive tissue assessment, 4D flow magnetic resonance imaging (MRI) enables full-field flow mapping, and micro-Computed Tomography (CT) permits high-resolution imaging at pre-clinical level.

3. 7. Computerised Microtomography : Non-invasive imaging and analysis of biological samples, with special reference to monitoring development of osteoporosis in small animals

   Författare :Mats Stenström; Gudrun Alm Carlsson; Carl Carlsson; Jim Elliot; Linköpings universitet; []
   Nyckelord :Computed microtomography; CμT; signal-to-noise ratio SNR ; non-invasive monitoring; morphological changes; Gastrectomized Sprague-Dawley; osteoporosis; MEDICINE; MEDICIN;

   Sammanfattning : The use of Computerised microtomography (CμT) in biomedical research is well established, with most applications developed at synchrotron facilities. The possibility to non-invasively monitor morphological changes in biological samples, makes it an attractive technique in biomedicine. LÄS MER

4. 8. Invasive and Non-Invasive Quantification of Cardiac Kinematics

   Författare :Katarina Kindberg; Matts Karlsson; Bjørn Skallerud; Linköpings universitet; []
   Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : The ability to measure and quantify myocardial motion and deformation provides a useful tool to assist in the diagnosis, prognosis and management of heart disease. Myocardial motion can be measured by means of several different types of data acquisition. LÄS MER

5. 9. Non invasive ventilation in people with cystic fibrosis

   Författare :Cecilia Rodriguez Hortal; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Cystic fibrosis (CF) is the most common life shortening autosomal recessive inherited disease affecting Caucasian people. The two main clinical characteristics of CF are progressive pulmonary disease and pancreatic insufficiency. The goal of airway clearance technique (ACT) is to improve ventilation and mucociliary clearance. LÄS MER

7. 10. Patterns of non-invasive imaging of carotid atherosclerosis

   Författare :Pranvera Ibrahimi; Michael Henein; Per Wester; Pompilio Faggiano; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiology; kardiologi;

   Sammanfattning : Atherosclerosis is an inflammatory disease that can be generalized, affecting more than one arterial bed simultaneously, or localized, manifested in one system. Ultrasound based measurements of plaque textural features, such as low grey scale median (GSM), echolucent (hypoechoic) plaque types and juxtaluminal black (hypoechoic) area (JBA) are manifestation of potentially unstable lesions.
