1. 11. New workflow method for ultrasound examinations

   Författare :Carina Stenman; Örjan Smedby; Staffan Wirell; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Background: Growing demand for ultrasound examinations and higher quality requirements motivate searching for routines combining the diagnostic accuracy of radiologist-performed examinations with the economical advantages of sonographerperformed examinations. One possible approach is to use strictly standardized examination protocols and documentation made by cine-loops that will give the radiologist access to all relevant information after the examination.

   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.

4. 13. Skin fibrosis, internal organ involvement and auto antibodies in systemic sclerosis: longitudinal development and impact on survival

   Författare :Roger Hesselstrand; Reumatologi och molekylär skelettbiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; muscle system; rheumatology locomotion; Skelett; muskelsystem; reumatologi; Skeleton; proteoglycan; pulmonary hypertension; organ involvement; auto antibodies; survival; systemic sclerosis; prognosis;

   Sammanfattning : Systemic sclerosis (SSc) is a connective tissue disease with a highly variable prognosis. Since new treatment strategies are emerging, there is a need for prognostic markers in order to help allocate patients to the optimal treatment. LÄS MER

5. 14. Mixture Effects of Environmental Contaminants

   Författare :Erik Lampa; Monica Lind; Jonas Björk; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mixtures; Environmental Contaminants; Atherosclerosis; Metabolic Syndrome; Boosting; Epidemiology;

   Sammanfattning : Chemical exposure in humans rarely consists of a single chemical. The everyday exposure is characterized by thousands of chemicals mainly present at low levels. Despite that fact, risk assessment of chemicals is carried out on a chemical-by-chemical basis although there is a consensus that this view is too simplistic. LÄS MER

7. 15. The use of ultrasound in the prediction of endometrial cancer in women with postmenopausal bleeding

   Författare :Gina Opolskiene; gynekologisk och prenatal ultraljudsdiagnostik Obstetrisk; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; endometrial neoplasms; ultrasonography; postmenopause; Doppler ultrasound;

   Sammanfattning : The aim of the work presented in this thesis was to identify the ultrasound methods and ultrasound features that are most useful for the prediction of endometrial cancer in patients with postmenopausal bleeding and sonographic endometrial thickness 4.5 mm or more. LÄS MER
