BACKGROUND Digital breast tomosynthesis (DBT) is a promising new technology. Some experimental clinical studies have shown positive results, but the future role and indications of this new technique, whether in a screening or clinical setting, need to be evaluated. PURPOSE To compare digital mammography and DBT in a side-by-side feature analysis for(More)
BACKGROUND Although a number of studies have evaluated the associations between use of postmenopausal hormone therapy (HT) and mammographic density, few have assessed the effects of the medications containing estradiol (E2) plus norethisterone acetate (NETA). In particular, there are few data on the effects of the low-dose E2/NETA regimen. METHODS We(More)
Breast cancers diagnosed between screening examinations among women who attend a breast cancer screening program are defined as interval cancers. The Norwegian Breast Cancer Screening Program started as a pilot project in 1996, and data from the first 2-year interval are available. Our study quantifies interval cancers in the pilot project and explores(More)
PURPOSE To retrospectively investigate whether different review designs have an influence on the estimate of missed interval cancer in a population-based breast cancer screening program. MATERIALS AND METHODS The Norwegian Breast Cancer Screening Program invites women aged 50-69 years to undergo biennial screening mammography. The current study was part(More)
OBJECTIVE To describe the distribution and prognostic tumour characteristics of interval breast cancers diagnosed in four periods after index screen (1-6, 7-12, 13-18 and 19+ months) in a population-based screening programme inviting women aged 50-69 years to biennial screening. SETTING The Norwegian Breast Cancer Screening Programme (NBCSP) Methods: In(More)
According to preset criteria, 1,194 women at risk for inherited breast carcinoma were selected and subjected to examination. Six hundred and three women were examined once, 591 were followed for a mean of 1.8 years. Twenty infiltrating cancers (median age 49 years) and 16 precancers (median age 44 years) were found, demonstrating that breast carcinoma(More)
Clinically healthy Norwegian elkhounds were tested for glucosuria by urine dipstick analysis and the results were compared with a group of dogs of other breeds during 15 dog shows. Fifty-two of 187 Norwegian elkhounds (27.3 per cent) and 15 of 202 dogs of other breeds (7.4 per cent) were glucosuric during the dog shows; the difference was statistically(More)
Hepatic abscesses represent the most common non-enteric complication of amebic infection, and occur in 1-25% of the patients. We describe two male patients, 44 and 47 years old, who presented hepatic abscesses after travelling in endemic regions. We stress the importance of accurate and early diagnosis. Ultrasonography and computed tomography were of major(More)
