21. Polymer-shelled Ultrasound Contrast Agents : Characterization and Application
Sammanfattning : Ultrasound-based imaging technique is probably the most used approach for rapid investigationand monitoring of anatomical and physiological conditions of internal organs and tissues.Ultrasound-based techniques do not require the use of ionizing radiation making the tests anexceptionally safe and painless.

22. Ultrasound and atherosclerosis. Evaluation of methods, risk factors and intervention
Sammanfattning : The importance of studying cardiovascular disease before the process leads to hard end-points has been recognised, and methods to quantify early atherosclerosis have been taken in use in many research centres around the world. An ultrasound method with a computer assisted image analysing system was developed in co-operation with the Wallenberg Laboratory for Cardiovascular Research and Chalmers University of Technology in Gothenburg, Sweden.

23. Ultrasound screening for fetal anomalies
Sammanfattning : We studied the prenatal detection rate of various malformations during a study period of 16 years in a population in southern Sweden consisting of 141 240 deliveries. The overall detection rate was 28.4% and the false positive diagnoses were very few. LÄS MER
24. Nano-Engineered Contrast Agents : Toward Multimodal Imaging and Acoustophoresis
Sammanfattning : Diagnostic ultrasound (US) is safer, quicker and cheaper than other diagnostic imaging modalities. Over the past two decades, the applications of US imaging has been widened due to the development of injectable, compressible and encapsulated microbubbles (MBs) that provide an opportunity to improve conventional echocardiographic imaging, blood flow assessment and molecular imaging.

25. Vascular ultrasound for the assessment of carotid atherosclerosis
Sammanfattning : Background: Atherosclerotic cardiovascular disease (CVD) is a common cause for mortality globally, and is expected to remain the single leading cause of death as the global population ages and as life expectancy increases.Cardiovascular screening models have been developed, and continue to be developed, to identify individuals at high-risk of CVD.
