2. 1. Dynamic Programming for Ultrasound Image Analysis of Atherosclerosis

   Author : Peter Holdfeldt; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; atherosclerotic plaque; ultrasound; classification; dynamic programming; carotid artery; image analysis; edge detection; graph cuts;

   Abstract : Cardiovascular diseases, due to atherosclerosis, are among the most common causes of death in the industrialized world. Atherosclerotic plaque composition as well as arterial diameter and wall thickness can be used to predict the risk of cardiovascular disease. These risk factors can be assessed non-invasively by ultrasound. READ MORE

4. 2. Ultrasound screening for fetal anomalies

   Author : Annamari Nikkilä; Lund Obstetrik och gynekologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; sexuality; Obstetrik; andrology; congenital malformations; ultrasound; gynekologi; andrologi; reproduktion; sexualitet; reproduction; gynaecology; Obstetrics; fetal diagnosis;

   Abstract : 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. READ MORE

5. 3. Ultrasound measurements of subclinical carotid atherosclerosis : methodological and clinical studies

   Author : Emma Nyman; Christer Grönlund; Ulf Näslund; Isabel Gonçalves; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atherosclerosis; ultrasound; carotid artery; carotid intima media thickness; carotid plaque; reproducibility; intervention; echogenicity; cardiovascular disease; hjärt- och kärlforskning;

   Abstract : Ultrasound measurements of subclinical carotid atherosclerosis have been evaluated as an additional parameter in risk evaluation of cardiovascular diseases (CVD). The overall aim of this thesis was to increase knowledge regarding ultrasound measurements of subclinical carotid atherosclerosis. READ MORE

6. 4. Ultrasound as predictor of perinatal outcome

   Author : Gisela Ghosh; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Doppler; Ultrasound; fetus; amniotic fluid index; nuchal cord; uterine artery; umbilical vein; fetal growth restriction; umbilical artery; pulsation; pregnancy;

   Abstract : The aim of the work described in this thesis was to evaluate the value of ultrasound examinations of the amniotic fluid, umbilical cord and blood flow velocity waveform of the fetal and placental vessels as predictors of the perinatal outcome. In the first study, the amniotic fluid index (AFI) measured on admission to the labour ward was evaluated in low-risk pregnancies. READ MORE

7. 5. Magnetomotive ultrasound for nanomedicine : a mechanistic approach to detection, evaluation and safety assessment

   Author : Sandra Sjöstrand; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetomotive; ultrasound; finite element analysis; cancer diagnosis; HT-29; Caco-2;

   Abstract : Cancer is one of the leading causes of death worldwide, but reliable diagnosis and staging can contribute to optimal treatment planning, and is a crucial factor in reducing mortality and maintaining quality of life. Soft tissue mechanical properties are promising indicators of cancer that can be assessed non-invasively using functional imaging. READ MORE
