1. 1. Breast cancer risk assessment and detection in mammograms with artificial intelligence

   Författare :Yue Liu; Kevin Smith; Hossein Azizpour; Fredrik Strand; Anders Eklund; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mammography; AI; Breast cancer risk; Breast cancer detection; Mammografi; AI; Bröstcancerrisk; Upptäckt av bröstcancer; Datalogi; Computer Science;

   Sammanfattning : Breast cancer, the most common type of cancer among women worldwide, necessitates reliable early detection methods. Although mammography serves as a cost-effective screening technique, its limitations in sensitivity emphasize the need for more advanced detection approaches. LÄS MER

3. 2. Improving breast cancer screening with artificial intelligence

   Författare :Victor Dahlblom; Malmö Diagnostisk radiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; breast cancer; artificial intelligence; screening; mammography; breast tomosynthesis; bröstcancer; artificiell intelligens; screening; mammografi; brösttomosyntes;

   Sammanfattning : Introduction: The current standard method for breast cancer screening is digital mammography (DM). Digital breast tomosynthesis (DBT) can detect more cancers but is more resource-demanding, not the least due to a more time-consuming reading, which hinders the implementation in screening. LÄS MER

4. 3. 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

5. 4. Measurement of Tumor Extent and Effects of Breast Compression in Digital Mammography and Breast Tomosynthesis

   Författare :Daniel Förnvik; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; digital mammography; breast tomosynthesis; breast compression; pressure distribution; breast cancer; circulating tumor cell;

   Sammanfattning : Breast cancer is the most common form of cancer affecting women in the western countries. Today x-ray digital mammography (DM) of the breast is commonly used for early detection of breast cancer. However, the sensitivity of mammography is limited, mainly due to the fact that a 3D volume is projected down to a 2D image. LÄS MER

7. 5. Evaluation of absorbed dose and image quality in mammography

   Författare :Bengt Hemdal; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; optically stimulated luminescence; radioluminescence; in vivo dosimetry; dose reduction; dose protocol; average glandular dose; absorbed dose; Breast cancer; mammography; Monte Carlo; image quality; image quality criteria; contrast-detail phantom;

   Sammanfattning : Mammography refers to the X-ray examination of the human breast, and is considered the single most important diagnostic tool in the early detection of breast cancer, which is by far the most common cancer among women. There is good evidence from clinical trials, that mammographic screening can reduce the breast cancer mortality with about 30%. LÄS MER
