2. 1. Orthopaedic measurements with computed radiography. Methodological development, accuracy, and radiation dose with special reference to the weight-bearing lower extremity and the dislocating patella

   Author : Jan Sanfridsson; Lund Ortopedi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; digital.; computer-assisted; Picture Archiving and Communication Systems; computed radiography; radiography; effective dose; radiation dosage; measurements; biomechanics; dislocating patella; musculoskeletal; patellofemoral joint; Knee joint; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

   Abstract : The overall aim of this study was to develop and evaluate a measurement system for computed radiography (CR) and Picture Archiving and Communication Systems (PACS), permitting measurements of long distances and angles in and between related images. The developed measurement system, which was based on the QUESTOR Precision Radiography (QPR) system, was applied to the weight-bearing knee with special reference to the dislocating patella.

4. 2. Radiological methods in rheumatoid arthritis and osteoarthritis

   Author : Tomas Söderman; Adel Shalabi; Anders Sundin; Suzanne Werner; Marie-Louise Wretling; Seppo Koskinen; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis; Cervical spine; Radiography; Computed tomography; Magnetic resonance imaging; ACL reconstruction; Knee laxity; Long-term evaluation; Osteoarthritis; KOOS; SF-36; Tegners Activity Scale; IKDC; Quality of life; Radiology; Radiologi;

   Abstract : The dissertation's theme is the critical role of radiology when evaluating two different groups of patients. Firstly, patients with rheumatoid arthritis (RA) of the cervical spine were studied to evaluate upper spine instability with dynamic computed tomography (CT). READ MORE

5. 3. Chest Tomosynthesis for Detection and Surveillance of Pulmonary Pathology. Studies on Cystic Fibrosis and Solid Pulmonary Nodules

   Author : Carin Meltzer; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; digital tomosynthesis; cystic fibrosis; solid lung nodules;

   Abstract : Introduction: Digital tomosynthesis (DTS) is a relatively new imaging modality in thoracic imaging. The technique is based on the equipment of conventional radiography, upgraded with a moving tube that enables separation of structures that are superimposed on chest x-ray (CXR). READ MORE

6. 4. Scaphoid fractures : Studies on diagnosis and treatment

   Author : Bertil Vinnars; Bengt Gerdin; Lars Adolfsson; Uppsala universitet; []
   Keywords : Surgery; Scaphoid Bone; Wrist Joint; Wrist Injuries; Fracture Healing; Cost of Illness; Health Care Costs; Outcome Assessment Health Care ; Arthroplasty; Radiography; Health status; Kirurgi;

   Abstract : Scaphoid fracture is most common in young individuals of working age. Without adequate diagnosis and treatment, long-term results are poor. Operative treatment is being recommended increasingly often instead of a long time in cast, although there is no evidence-based support for its superiority. READ MORE

7. 5. Maxillofacial cone beam computed tomography (CBCT) : aspetcs on optimisation

   Author : Ayman Al-Okshi; Malmö högskola; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CBCT; OPTIMISATION; DOSAGE;

   Abstract : Inom odontologisk såväl som inom medicinsk radiologi sker en snabb utveckling av nya tekniker. Nya metoder för att kunna diagnosticera och följa sjukdomsförlopp över tid introduceras. Cone-Beam Computed Tomography (CBCT) är en sådan ny teknik, som introducerades inom odontologin under sent 1990-tal. READ MORE
