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

    Author : Anetta Bolejko; Institutionen för hälsovetenskaper; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Kristina Lång; Malmö Diagnostisk radiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

    Author : Tony Svahn; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 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 ;

    Abstract : 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.

  5. 5. Incidence and interval breast cancers in retrospective assessment

    Author : Kerstin Moberg; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Breast neoplasm; mammography screening; computer aided detection; interval breast cancer; incidence breast cancer;

    Abstract : The aims of this thesis were to investigate how different review methods used for radiological classification of breast cancers would affect the proportion judged to be false negative, to investigate how computer aided detection (CAD) would affect screening sensitivity, to study the balance between false positive and false negative results and to investigate patient outcome in relation to review result. In a mass screening programme in Stockholm, commencing in 1989 and performed at five independent screening units, interval cancers (presenting in the time interval between two consecutive screening examinations) from two of the units, 103 women, and incidence cancers (diagnosed at subsequent screening examination) from one of the units, 117 women, diagnosed up until July 1993 were identified.
