2. 1. 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

   Abstract : Background: Second trimester ultrasound examination among pregnant women in Sweden is almost universal. The detection of a fetal malformation on ultrasound puts health care providers and pregnant women in a difficult and precarious situation. READ MORE

5. 3. 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

6. 4. Fetal Anomalies : Surveillance and Diagnostic Accuracy of Ultrasound and Magnetic Resonance Imaging

   Author : Hashem Amini; Ove Axelsson; Johan Wikström; Pelle Lindqvist; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pregnancy termination; fetal anomalies; antenatal diagnosis; ultrasound; second trimester; fetal MRI; CNS anomalies; pregnancy management; non-CNS anomalies; fetal autopsy; birth defects registry; ascertainment; spina bifida; cleft lip palate; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; Obstetrics and gynaecology; Obstetrik och gynekologi; Obstetrik och gynekologi; Obstetrics and Gynaecology;

   Abstract : The aims were to investigate the accuracy of ultrasound in diagnosis of structural fetal anomalies with special focus on false positive findings (I), to evaluate the additional value of second trimester fetal MRI on pregnancy management (II-III) and to estimate the ascertainment in the Swedish Birth Defects Registry and incidence of spina bifida and cleft lip/palate (IV). Retrospectively, 328 fetal autopsies were identified where pregnancies were terminated due to ultrasonographically diagnosed fetal anomalies. READ MORE

7. 5. On the Use of Ultrasound Phase Data for Arterial Characterization

   Author : Tobias Erlöv; Avdelningen för Biomedicinsk teknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Atherosclerosis; Ultrasound; Carotid Artery; Plaque Characterization; Scatter Size; Longitudinal Movement; Intima-Media Thickness;

   Abstract : Atherosclerosis is one of the major causes of death in the world. It is an inflammatory disease in the arteries which causes a gradual increase in arterial wall thickness and stiffness. Eventually a plaque could be formed, protruding into the artery and partially occluding the blood flow. READ MORE
