    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; scoliosis; spinal fusion; brace treatment; radiography; magnetic resonance imaging; osteoarthritis; spirometry; outcome studies; quality of life;

    Abstract : Introduction: The long term outcome of treatment for adolescent idiopathic scoliosis (AIS), with brace or surgery, has previously not been fully established.Aims: To evaluate the outcome in terms of radiological appearance, degenerative changes, pulmonary function and different aspects of health related quality of life at least twenty years after completed treatment.

  4. 2. Tomosynthesis in pulmonary cystic fibrosis

    Author : Kristina Vult von Steyern; Lund Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cystic fibrosis; Lung; Radiation dose; Radiography; Scoring methods; Tomography; spiral computed; X-ray computed;

    Abstract : The aims of this thesis were to investigate whether chest tomosynthesis might be used in pulmonary cystic fibrosis, to design and validate a tomosynthesis scoring system, and to determine the effective dose from chest tomosynthesis in children. In a prospective study starting in 2008 clinical chest radiography or computed tomography (CT) were supplemented with a tomosynthesis examination of the lungs. READ MORE

  5. 3. Effects of high load on the growing spine. Experimental studies anda long-term follow-up of top athletes

    Author : Olof Lundin; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Athletes; adolescence; back pain; compression load; disc degeneration; intervertebral disc; radiography; spine; porcine spine; nucleus pulposus; vertebral endplate;

    Abstract : A high prevalence of radiological abnormalities of the spine has been reported in some physically demanding sports. The significance and aetiology of these radiological abnormalities are still a matter of controversy and the long-term effects are not known. READ MORE

  6. 4. Characterisation and application of a laser-based hard x-ray source

    Author : Matthias Grätz; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray spectroscopy; radiography; medical imaging; differential imaging; time-gated imaging; scatter reduction; Monte Carlo simulation; Atomic and molecular physics; computed tomography; Fysicumarkivet A:1998:Grätz; laser-produced plasma; Atom- och molekylärfysik; X-ray sources;

    Abstract : Hard X-rays are generated by focusing 110 fs laser pulses with intensities of about 1017 W·cm-2 onto solid metal targets. Characteristic properties of this X-ray source are the small source size, the short pulse duration and the high peak flux. READ MORE
