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

    University dissertation from Umeå : Strålningsvetenskaper

    Author : Anna Ljungkvist; Umeå universitet.; [2003]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; tumor microenvironment; double hypoxic marker method; proliferation; hypoxia; hypoxic half-life; Radiologisk forskning; MEDICINE Physiology and pharmacology Radiological research; MEDICIN Fysiologi och farmakologi 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

    University dissertation from Umeå : Umeå universitet

    Author : Patrik Brynolfsson; Umeå universitet.; [2017]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quantitative imaging; tumor imaging; dynamic contrast-enhanced MRI; diffusion weighted MRI; texture analysis; radiofysik; radiofysik;

    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

    University dissertation from Umeå : Umeå Universitet

    Author : Ida Häggström; Umeå universitet.; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Dynamic positron emission tomography; PET; tumor imaging; compartment modeling; Monte Carlo; radiofysik; radiofysik;

    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

    University dissertation from Stockholm : KTH

    Author : Mikaela Friedman; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Affibody; affinity maturation; phage display selection; EGFR; molecular imaging; protein engineering; tumor targeting; TECHNOLOGY Bioengineering; TEKNIKVETENSKAP 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

    University dissertation from Institutionen för datavetenskap och elektronik

    Author : Tommy Gunnarsson; Mälardalens högskola.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microwave Imaging; Breast tumor detection; Inverse problems; Mammography; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik 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
