  2. 2. Interpretation of diagnostic information given patient characteristics

    Author : Martin Gellerstedt; Hans Åhlfeldt; Sweden The Sahlgrenska Academy at Göteborg University Institute of Biomedicine; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; reference values; diagnostic theory; diagnostic tests; partitioning; prevalence function;

    Abstract :  The aim with this thesis was to describe, exemplify and develop theory for reference values and diagnostic tests, especially focusing on the variability between individuals. To facilitate interpretation of medical information it is common to establish some kind of limit. There are several different rationales for the choice of such a limit. READ MORE

  4. 4. Fetal Anomalies : Surveillance and Diagnostic Accuracy of Ultrasound and Magnetic Resonance Imaging

    Author : Hashem Amini; Ove Axelsson; Johan Wikström; Pelle Lindqvist; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pregnancy termination; fetal anomalies; antenatal diagnosis; ultrasound; second trimester; fetal MRI; CNS anomalies; pregnancy management; non-CNS anomalies; fetal autopsy; birth defects registry; ascertainment; spina bifida; cleft lip palate; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; Obstetrics and gynaecology; Obstetrik och gynekologi; Obstetrik och gynekologi; Obstetrics and Gynaecology;

    Abstract : The aims were to investigate the accuracy of ultrasound in diagnosis of structural fetal anomalies with special focus on false positive findings (I), to evaluate the additional value of second trimester fetal MRI on pregnancy management (II-III) and to estimate the ascertainment in the Swedish Birth Defects Registry and incidence of spina bifida and cleft lip/palate (IV). Retrospectively, 328 fetal autopsies were identified where pregnancies were terminated due to ultrasonographically diagnosed fetal anomalies. READ MORE

  5. 5. Computer-Assisted Diagnosis for the Interpretation of Bone Scintigraphy. A new approach to improve diagnostic accuracy

    Author : May Sadik; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Diagnostic accuracy; Radionuclide imaging; Bone metastases; Breast cancer; Prostate cancer;

    Abstract : The most common cancers in the western countries are breast cancer in women and prostate cancer in men, and these cancer types, together with lung cancer, often metastasise to the skeleton. Bone scan is used to determine whether metastases are present, and the result of the examination serves as a guide in the choice of treatment strategy. READ MORE
