2. 1. 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

4. 2. Laser-Matter Interactions at Extreme Irradiance: X-ray Generation and Relativistic Channelling

   Author : Anders Sjögren; Atomfysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; relativistic self-focusing; particle acceleration; x-ray generation; radiography; Laserteknik; Laser technology; laser-produced plasma; light scattering; Fysicumarkivet A:2002:Sjögren;

   Abstract : This thesis summarizes experimental work in which the powerful Ti:sapphire lasers at the High Power Laser Facility at the Lund Laser Centre have been employed to investigate laser-produced X-rays and relativistic channelling. These lasers produce short pulses, of the order of 50 fs, with energies ranging from 1 mJ to 1 J. READ MORE

5. 3. Scaphoid Fractures - epidemiology, diagnosis and treatment

   Author : Peter Jörgsholm; Malmö Handkirurgi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Scaphoid fracture; carpal fracture; paediatric; radiography; CT; MRI; arthroscopy; scapholunate ligament injury; radial comminution; surgical treatment; conservative treatment; fracture union;

   Abstract : Abstract The scaphoid is the most commonly fractured carpal bone. The diagnosis is difficult and untreated the long-term results are poor. Approximately 10% do not unite even if they are treated properly. The aim of this thesis was to study scaphoid fracture epidemiology, diagnosis and treatment. READ MORE

6. 4. Epidemiology of osteoarthritis in Sweden. Register and cohort studies on prevalence and mortality

   Author : Aleksandra Turkiewicz; Lund Ortopedi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Epidemiology; Osteoarthritis; Knee; Hip; Radiography; Mortality; Registers; Missing data;

   Abstract : Osteoarthritis (OA) is the most common form of arthritis and often causes pain and functional impairment. Despite its high burden on society, knowledge about the occurrence of OA and its associated mortality is sparse. READ MORE

7. 5. Radiographic follow-up analysis of Br?nemark? dental implants

   Author : Solweig Sundén Pikner; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cluster effect; Dental implants; Dependency; Diagnostic accuracy; Long-term follow-up; Marginal bone level; Observer variation; Osseointegration; Prediction;

   Abstract : Radiography plays an important role in clinical routine practice and in research projects evaluating dental implants, among them Br?nemark? System. Presence of a peri-implant radiolucency has been used in studies as a criterion for implant failure without knowledge of its diagnostic accuracy. READ MORE
