  1. 1. CT Colonography: implementation and technical developments

    Författare :Valeria A Fisichella; Göteborgs universitet; []
    Nyckelord :X-ray Computed Tomography; Computed Tomographic Colonography; Computer-Assisted Image Processing; Three-Dimensional Imaging; Colonoscopy; Colon; Rectum; Colorectal Neoplasms; Computer-Assisted Diagnosis; Ionizing Radiation;

    Sammanfattning : Background: Computed tomographic colonography (CTC) is a minimally invasive imaging method for the detection of colorectal neoplasms. Uncertainty about its diagnostic performance, optimal visualization method, long learning curve and radiation exposure are among problems with CTC, affecting its implementation in routine health care.

  4. 3. Aspects on diverticular disease

    Författare :Fredrik Hjern; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Diverticular disease; diverticulitis; risk factors; antibiotics; CT colonography; colonoscopy; genital fistula; medical and surgical treatment;

    Sammanfattning : Objective: The aims of this thesis were to evaluate the influence of ethnicity and other sociodemographic factors on the rate of diverticular disease (DD) (Paper I), to compare findings specific for DD and acceptance of CT Colonography (CTC) and conventional Colonoscopy (CC) in patients examined after diverticulitis (AD) (Paper II), to evaluate the value of antibiotics in conservative treatment of patients with mild AD (Paper III) and to study patients with diverticular fistulas to the female genital tract (Paper IV). Methods: In paper I, Swedish national registers with information about health and socio-demographic indicators were used to study ethnicity and other socio-demographic factors and the risk of hospital admission due to DD in a national cohort (4.

  5. 4. Detection and staging of colonic lesions using computed tomography and magnetic resonance imaging

    Författare :Erik Rollvén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In Sweden, more than 6000 new patients were diagnosed with colorectal cancer in 2015 of which over 4000 patients had colon cancer and 1800 died from the disease. It is the second most common cancer after breast- and prostate cancer. In the last decade, significant improvement in the treatment of both rectal and colon cancer have been achieved. LÄS MER
