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

    Author : Kristina Lång; Malmö Diagnostisk radiologi; []
    Keywords : 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

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

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

    Abstract : 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. READ MORE

  5. 3. Improving breast cancer screening with artificial intelligence

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

    Abstract : 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.

  6. 4. HER2-receptor quantification in breast cancer patients by imaging with ABY-025 Affibody and PET

    Author : Ali Alhuseinalkhudhur; Henrik Lindman; Jens Sörensen; Mark Lubberink; Irina Velikyan; Rimma Axelsson; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; Breast cancer; HER2; Affibody; ABY-025; Molecular imaging; Kinetic modelling; Brain metastasis;

    Abstract : Breast cancer is the most common malignancy in women worldwide. Human epidermal growth factor receptor type 2 (HER2) is overexpressed in up to 20% of breast cancer cases and is considered an important prognostic factor and a therapeutic target. READ MORE

  7. 5. The Role of Projected Anatomy, Random Noise, and Spatial Resolution on Clinical Image Quality in Digital Mammography

    Author : Mark Ruschin; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 3D breast imaging; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; hybrid images; dose reduction; spatial resolution; pixel size; Breast cancer; digital mammography; radiologi; tomografi; medicinsk instrumentering; breast tomosynthesis;

    Abstract : Due to the recent advances in digital detector technology, there is an increasing trend in the use of digital mammography (DM) as a concurrent modality with screen-film mammography (SFM). In order to fully realize its potential, the components of a DM system should be optimized with respect to clinical image quality in order for clinicians to make accurate diagnoses. READ MORE
