1. 1. Psychosocial consequences of false-positive mammography among women attending breast cancer screening. Assessment, prediction, and coping

   Författare :Anetta Bolejko; Institutionen för hälsovetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; women’s health; false-positive screening mammography; breast cancer screening; predictors; coping; Consequences of Screening – Breast Cancer questionnaire; Rasch model; psychometric evaluation;

   Sammanfattning : One side-effect of breast cancer (BC) screening is a false-positive mammogram among healthy women. That is, finding(s) on a screening mammogram that lead to additional breast examinations but where the woman is eventually considered free from BC. There is evidence of short-term psychosocial consequences of false-positive BC screening. LÄS MER

3. 2. Breast tomosynthesis – new perspectives on breast cancer screening

   Författare :Kristina Lång; Malmö Diagnostisk radiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast cancer; Breast tomosynthesis; Mammography; Breast cancer screening; Cancer detection rate; Recall rate; False positive rate; Image perception; Reading time; Lesion visualisation; Detection error;

   Sammanfattning : Abstract: Mammography is currently the established method in breast cancer screening, although the sensitivity is known be affected by overlapping tissue concealing tumours. Breast tomosynthesis takes advantage of multiple exposures at different angles reducing the negative effect of obscuring tissue. LÄS MER

4. 3. Deep learning algorithms for tumor detection in screening mammography

   Författare :Mattie Salim; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Population-wide mammography screening was fully implemented in Sweden in 1997. The implementation has helped to identify breast cancer at earlier stages and thereby lowered mortality by 30-40%. However, it still has its limitations, many studies have shown a discrepancy between radiologist when assessing mammographic examinations. LÄS MER

5. 4. MICROWAVE IMAGING OF BIOLOGICAL TISSUES: applied toward breast tumor detection

   Författare :Tommy Gunnarsson; Ylva Bäcklund; Denny Åberg; Hans Sköld; Mikael Persson; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microwave Imaging; Breast tumor detection; Inverse problems; Mammography; Electronics; Elektronik; Elektronik;

   Sammanfattning : Microwave imaging is an efficient diagnostic modality for non-invasively visualizing dielectric contrasts of non-metallic bodies. An increasing interest of this field has been observed during the last decades. Many application areas in biomedicine have been issued, recently the breast tumor detection application using microwave imaging. LÄS MER

7. 5. Evaluation of image quality and diagnostic accuracy in breast tomosynthesis. Comparison with digital mammography and estimates of radiation risk

   Författare :Tony Svahn; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diagnostic accuracy; breast tomosynthesis BT ; digital mammography DM ; average glandular dose AGD ; receiver operating characteristics ROC ; risk assessment; search-model SM ; proper ROC PROPROC ;

   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.
