1. 11. Quantitative Magnetic Resonance Imaging of the Brain : Applications for Tissue Segmentation and Multiple Sclerosis

   Författare :Janne West; Peter Lundberg; Anne-Marie Landtblom; Marcel Jan Bertus Warntjes; Örjan Smedby; Olof Dahlqvist Leinhard; Per Thunberg; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Magnetic resonance imaging (MRI) is a sensitive technique for assessing white matter (WM) lesions in multiple sclerosis (MS), but there is a low correlation between MRI findings and clinical disability. Because of this, other pathological changes are of interest, including changes in normal appearing white matter (NAWM) and diffusely abnormal white matter (DAWM). LÄS MER

3. 12. Physical Aspects of Thermotherapy - A study of heat transport with a view to treatment optimisation

   Författare :Johan Olsrud; Sektion V; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance; non-invasive; temperature; coagulation; prostatic; menorrhagia; liver tumour; finite element method FEM ; thermal conductivity; intracavitary; interstitial; laser; Thermotherapy; hyperthermia; MRI; Medicine human and vertebrates ; Medicin människa och djur ; Physics; Fysik; Fysicumarkivet A:1998:Olsrud;

   Sammanfattning : Local treatment with the aim to destruct tissue by heating (thermotherapy) may in some cases be an alternative or complement to surgical methods, and has gained increased interest during the last decade. The major advantage of these, often minimally-invasive methods, is that the disease can be controlled with reduced treatment trauma and complications. LÄS MER

4. 13. Hemodynamic assessment in patients with congenital heart disease using magnetic resonance imaging

   Författare :Pia Sjöberg; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Around 1000 children are born with a heart disease in Sweden every year and today most of these children survive and reach adult age. There are around 2.3 million grownups with congenital heart disease in Europe today, a number that is expected to continue to increase. LÄS MER

5. 14. Resilient Appliance Therapy of Temporomandibular Disorders. Subdiagnoses, Sense of Coherence and Treatment Outcome

   Författare :Håkan Nilsson; Malmö högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stomatognathic physiology; TMD-pain; resilient appliance treatment;

   Sammanfattning : Temporomandibulär dysfunktion (TMD) med käk- och/eller ansiktssmärta,med eller utan nedsatt käkfunktion, är vanligt förekommandetillstånd i befolkningen. Tandpressning och gnissling,som kan vara utlösta på grund av hög psykosocial stress, utgör tillsammanseller parallellt med bland annat käktrauma, orsaksfaktorersom kan ge upphov till TMD-symtom som smärta.

7. 15. Development and application of rule- and learning-based approaches within the scope of neuroimaging : Tensor voting, tractography and machine learning

   Författare :Daniel Jörgens; Rodrigo Moreno; Örjan Smedby; Chunliang Wang; Jesper Andersson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tensor voting; tractography; deep learning; tractogram filtering; diffusion magnetic resonance imaging; tensorröstning; traktografi; djupinlärning; traktogramfiltrering; diffusions-MRT; Tillämpad medicinsk teknik; Applied Medical Technology;

   Sammanfattning : The opportunity to non-invasively probe the structure and function of different parts of the human body makes medical imaging an indispensable tool in clinical diagnostics and related fields of research. Especially neuroscientists rely on modalities like structural or functional Magnetic Resonance Imaging, Computed Tomography or Positron Emission Tomography to study the human brain in vivo. LÄS MER
