1. 6. Development of methods for evaluation and optimization of chest tomosynthesis

   Författare :Angelica Svalkvist; Göteborgs universitet; []
   Nyckelord :Chest tomosynthesis; Evaluation; Optimization; Simulation; Image Quality; Dosimetry; Dose reduction; Nodule simulation; Validation;

   Sammanfattning : Tomosynthesis is a low-dose technique that has attracted increasing interest from the medical imaging community during the past decade. Tomosynthesis refers to the technique of acquiring a number of projection radiographs using extremely low exposure over a limited angular range, and using these radiographs to reconstruct slices of the imaged object.

3. 7. Equity and equality : case detection of tuberculosis among women and men in Vietnam

   Författare :Anna Thorson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Tuberculosis; case detection; gender; DOTS; health-seeking behaviour; doctor s delay; equity; chest x-ray; Vietnam;

   Sammanfattning : Background: The global Tuberculosis (TB) control strategy recommended by the WHO, DOTS, is based on identification of sputum smear-positive pulmonary TB cases by self-referral to health services. The target set by the WHO is to detect 70% of all sputum smear-positive TB cases. LÄS MER

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

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

   Sammanfattning : 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). LÄS MER

5. 9. Clinical aspects on central venous cannulation

   Författare :Andreas Pikwer; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Central venous catheters are mainly being used for reliable infusion of fluids and potentially irritant drugs, for haemodialysis, and for assessment of right atrial or central venous pressure (RAP/CVP). Current guidelines state that central venous catheterization should be followed-up by immediate anterior-posterior chest X-ray to confirm appropriate positioning and to detect iatrogenic pneumothorax.

7. 10. Treatment of pneumothorax : Aspects on diagnosis, treatment technique and pain relief during drainage treatment

   Författare :Olle Engdahl; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Pneumothorax is the term used for all conditions where air is present in the pleural cavity outside the confinement of the lung. Active treatment of pneumothorax often consists of the introduction of a pleural drain and the application of a continuous vacuum to keep the collapsing lung expanded until the lesion has healed.
