  1. 1. Imaging the tumor microenvironment : the dynamics and modification of hypoxia

    Author : Anna Ljungkvist; Peggy L. Olive; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; tumor microenvironment; double hypoxic marker method; proliferation; hypoxia; hypoxic half-life; Radiologisk forskning; Radiological research; Radiologisk forskning; diagnostisk radiologi; Diagnostic Radiology;

    Abstract : The tumor vasculature is poor and heterogeneous which may result in inadequate oxygenation and changed energy status. In addition the balance between cell proliferation and the rate of cell death is disturbed, which results in tumor growth. READ MORE

  2. 2. Applications of statistical methods in quantitative magnetic resonance imaging

    Author : Patrik Brynolfsson; Anders Garpebring; Tufve Nyholm; Eirik Malinen; Umeå universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quantitative imaging; tumor imaging; dynamic contrast-enhanced MRI; diffusion weighted MRI; texture analysis; radiofysik; radiation physics;

    Abstract : Magnetic resonance imaging, MRI, offers a vast range of imaging methods that can be employed in the characterization of tumors. MRI is generally used in a qualitative way, where radiologists interpret the images for e.g. diagnosis, follow ups, or assessment of treatment response. READ MORE

  3. 3. Quantitative methods for tumor imaging with dynamic PET

    Author : Ida Häggström; Anne Larsson; Mikael Karlsson; Lennart Johansson; Jens Sörensen; Magnus Dahlbom; Umeå universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Dynamic positron emission tomography; PET; tumor imaging; compartment modeling; Monte Carlo; radiofysik; radiation physics;

    Abstract : There is always a need and drive to improve modern cancer care. Dynamic positron emission tomography (PET) offers the advantage of in vivo functional imaging, combined with the ability to follow the physiological processes over time. READ MORE

  4. 4. Affibody molecules targeting the epidermal growth factor receptor for tumor imaging applications

    Author : Mikaela Friedman; Stefan Ståhl; Fredrik Nilsson; James S. Huston; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Affibody; affinity maturation; phage display selection; EGFR; molecular imaging; protein engineering; tumor targeting; Bioengineering; Bioteknik;

    Abstract : Tumor targeting and molecular imaging of protein markers specific for or overexpressed in tumors can add useful information in deciding upon treatment and assessing the response to treatment for a cancer patient. The epidermal growth factor receptor (EGFR) is one such tumor-associated receptor, which expression is abnormal or upregulated in various cancers and associated with a poor patient prognosis.

  5. 5. 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
