  2. 2. Diagnosing pneumonia in primary care : Aspects of the value of clinical and laboratory findings and the use of chest X-ray

    Författare :Anna Moberg; Magnus Falk; Jakob Paues; Sven Göran Fransson; Ronny Gunnarsson; Linköpings universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : It is important to identify patients with pneumonia because it is potentially a serious disease, often of bacterial origin, that should be treated with antibiotics. It is equally important to identify those with acute bronchitis, a self-limiting disease, that should not be treated with antibiotics. LÄS MER

  3. 3. Tomosynthesis in pulmonary cystic fibrosis

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

    Sammanfattning : 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. LÄS MER

  4. 4. Quantifying the quality of medical x-ray images. An evaluation based on normal anatomy for lumbar spine and chest radiography

    Författare :Anders Tingberg; Malmö Medicinsk strålningsfysik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; normal anatomy; free response forced error FFE ; receiver operating characteristics ROC ; visual grading analysis VGA ; European image criteria; quantifying clinical image quality; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : Optimisation in diagnostic radiology requires accurate methods for determination of patient absorbed dose and clinical image quality. Simple methods for evaluation of clinical image quality are at present scarce and this project aims at developing such methods. LÄS MER

  5. 5. Development of methods for evaluation and optimization of chest tomosynthesis

    Författare :Angelica Svalkvist; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    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.
