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

    Detta är en avhandling från Umeå : Strålningsvetenskaper

    Författare :Anna Ljungkvist; Peggy L. Olive; [2003]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Patrik Brynolfsson; Anders Garpebring; Tufve Nyholm; Eirik Malinen; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quantitative imaging; tumor imaging; dynamic contrast-enhanced MRI; diffusion weighted MRI; texture analysis; radiofysik; radiation physics;

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Stockholm : KTH

    Författare :Mikaela Friedman; Stefan Ståhl; Fredrik Nilsson; James S. Huston; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Affibody; affinity maturation; phage display selection; EGFR; molecular imaging; protein engineering; tumor targeting; TECHNOLOGY Bioengineering; TEKNIKVETENSKAP Bioteknik;

    Sammanfattning : 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.

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

    Detta är en avhandling från Institutionen för datavetenskap och elektronik

    Författare :Tommy Gunnarsson; Ylva Bäcklund; Denny Åberg; Hans Sköld; Mikael Persson; [2007]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 5. Preclinical Molecular Imaging using Multi-Isotope Digital Autoradiography - Techniques and Applications

    Detta är en avhandling från Institutionen för datavetenskap och elektronik

    Författare :Anders Örbom; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autoradiography; Radioimmunotherapy; Antibodies; Molecular Imaging; Multi-Radionuclide Imaging; Silicon-strip detector;

    Sammanfattning : Molecular imaging, both in vivo and ex vivo, is playing an increasingly important role in preclinical medical research. When using radionuclide-labeled tracers, e.g. in the development of radiopharmaceuticals for diagnostic imaging or for radionuclide therapy, quantitative in vivo imaging can be performed using emission tomography.
