1. CT Colonography: implementation and technical developments
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.

3. Aspects on diverticular disease
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.
