  2. 1. Array based genetic profiling of bone and soft tissue tumors

    Author : Karolin Hansén Nord; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : In this thesis, genetic alterations in bone and soft tissue tumors have been investigated with the purpose of identifying regions of importance for tumor development, diagnosis and prognosis. This has primarily been performed by array comparative genomic hybridization analysis and gene expression profiling of cytogenetically analyzed tumors. READ MORE

  4. 2. CYTOGENETIC AND MOLECULAR GENETIC CHARACTERIZATION OF LIPOMAS

    Author : Hammurabi Bartuma; Avdelningen för klinisk genetik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; soft tissue tumors; adipocytic tumors; conventional lipomas; spindle cell lipoma; HMGA2; cytogenetic; molecular genetic; SNP array; GGE;

    Abstract : The focus of this thesis was to study cytogenetic and molecular genetic aberrations in lipomas. For this purpose, chromosome banding analysis, fluorescence in situ hybridization (FISH), as well as high resolution single nucleotide polymorphism (SNP)–arrays were used to identify recurrent chromosomal aberrations in lipomas.

  5. 3. Clinical and Biological Patterns in Soft Tissue Sarcoma

    Author : Emelie Styring; Lund Ortopedi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiosarcoma; radiation-associated sarcoma; irradiated; RET; KIT; MYC.;

    Abstract : Soft tissue sarcomas (STSs) are rare malignant tumors, of which 3/4 are high-grade and 1/3 metastasize. For optimal management, STSs should be treated at multidisciplinary sarcoma centers. READ MORE

  6. 4. Magnetic resonance imaging with ultrashort echo time as a substitute for X-ray computed tomography

    Author : Adam Johansson; Tufve Nyholm; Karlsson Mikael; James Balter; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; magnetic resonance imaging; computed tomography substitute; ultrashort echo time; parallel imaging; radial imaging; radiofysik; radiation physics;

    Abstract : Radiotherapy dose calculations have evolved from simple factor based methods performed with pen and paper, into computationally intensive simulations based on Monte Carlo theory and energy deposition kernel convolution.Similarly, in the field of positron emission tomography (PET), attenuation correction, which was originally omitted entirely, is now a crucial component of any PET reconstruction algorithm.
