1. 26. Computer Assisted Coronary CT Angiography Analysis : Disease-centered Software Development

   Författare :Chunliang Wang; Örjan Smedby; Anders Persson; Hans Frimmel; Markus Müller; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coronary CTA; vessel segmenation; centerline tracking; visualization; Radiology; Radiologi; Image analysis; Bildanalys; Cardiology; Kardiologi;

   Sammanfattning : The substantial advances of coronary CTA have resulted in a boost of use of this new technique in the last several years, which brings a big challenge to radiologists by the increasing number of exams and the large amount of data for each patient. The main goal of this study was to develop a computer tool to facilitate coronary CTA analysis by combining knowledge of medicine and image processing. LÄS MER

3. 27. Cardiac hypertrophy : transcription patterns, hypertrophic progression and extracellular signalling

   Författare :Nina Gennebäck; Stellan Mörner; Anders Waldenström; Urban Hellman; Ali J Marian; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac hypertrophy; HCM; gene expression; OPLS-DA; multivariate dataanalysis; cardiomyocytes; exosomes; microvesicles; Medicine; medicin;

   Sammanfattning : Background: The aim of this thesis was to study transcription patterns and extracellular signalling of the hypertrophic heart to better understand the mechanisms initiating, controlling and maintaining cardiac hypertrophy.Cardiac hypertrophy is a risk factor for cardiovascular morbidity and mortality.

4. 28. Work-related cardiovascular disease

   Författare :Helena Eriksson; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Occupational noise; shift work; job strain; seafarer; cardiovascular disease;

   Sammanfattning : The overall aim of this thesis was to study occupational risk factors for cardiovascular disease, particularly, occupational noise, job strain and shift work. Incidence of cardiovascular disease was analysed in a general population sample, the Primary Prevention Study, in relation to exposure to noise and job strain. LÄS MER

5. 29. On the use of computed tomography in cardiac imaging

   Författare :Jakob De Geer; Anders Persson; Jan Engvall; Michael Sandborg; Örjan Smedby; Åse Johnsson; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : BackgroundCardiac Computed Tomography Angiography (CCTA) is becoming increasingly useful in the work‐up of coronary artery disease (CAD). Several potential methods for increasing the diagnostic yield of cardiac CT are available. LÄS MER

7. 30. Polymer-shelled Ultrasound Contrast Agents : Characterization and Application

   Författare :Dmitry Grishenkov; Leif Kari; Lars-Åke Brodin; Michel Versluis; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ultrasound; contrast agents; microbubbles; polymer; perfusion; Acoustics; Akustik; Material physics with surface physics; Materialfysik med ytfysik; Cardiovascular medicine; Kardiovaskulär medicin; Cardiology; Kardiologi;

   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.
