6. Evaluation of image quality and diagnostic accuracy in breast tomosynthesis. Comparison with digital mammography and estimates of radiation risk
Sammanfattning : Recent advances in the digital detector technology have paved the way for modalities such as two-dimensional digital mammography (DM) and three-dimensional breast tomosynthesis (BT). In this work, experimental studies were conducted to investigate the influence of reducing the average glandular dose (AGD) on detection of simulated lesions in DM and to compare the diagnostic accuracy of BT and DM.

7. Calcified carotid artery atheromas in panoramic radiographs : diagnostic reliability and association to cardiovascular disease, diabetes and periodontitis
Sammanfattning : Objective: Incidental findings of Calcified Carotid Artery Atheromas (CCAA) on Panoramic Radiographs (PRs) of the jaws can be a risk marker for cardiovascular disease. The objectives for the thesis were to investigate the association between CCAA and 1) Myocardial Infarction (MI), 2) periodontitis, 3) diabetes and 4) estimated cardiovascular risk. LÄS MER
8. Tuberculosis and HIV : evaluation of new tests for diagnostic accuracy, cost-effectiveness and effect on treatment of tuberculosis in Smear-Negative HIV-positive patients in Uganda
Sammanfattning : Background: Despite tremendous progress in the control of the global tuberculosis (TB) epidemic during the past decade, it is still a major health problem even today. The burden of TB is particularly severe in sub-Sahara Africa where TB and HIV co-infection is common, especially in those who are smear-negative. LÄS MER
9. Diagnostic Accuracy of Tuned Aperture Computed Tomography (TACT®)
Sammanfattning : The diagnostic accuracy of Tuned Aperture Computed Tomography (TACT) was evaluated for a variety of diagnostic tasks. Drawbacks of 2D radiography, lack of accessibility and high cost associated with advanced imaging modalities prompted these studies. LÄS MER
10. Colonic Diverticulitis : Diagnostic and Therapeutic Aspects
Sammanfattning : The overall aims of this thesis were to evaluate diagnostic and therapeutic aspects of colonic diverticulitis. In the first study, a systematic review of the literature was performed to evaluate radiological diagnostics for patients with acute left-sided diverticulitis. LÄS MER
