  2. 1. Small-Scale Absorbed Dose Modelling in Selective Internal Radiation Therapy : Microsphere Distribution in Normal Liver Tissue

    Author : Jonas Högberg; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; clusters; dosimetry; heterogeneity; liver; microspheres; radioembolisation; simulations; SIRT; surgery; yttrium-90;

    Abstract : Radioembolisation (RE), with yttrium-90 (90Y) labelled microspheres, is an increasingly common treatment method for unresectable liver tumours. The tolerable mean absorbed dose for normal liver (NL) tissue is higher in RE than in External Beam Radiation Therapy (EBRT); absorbed dose heterogeneity is thought to be one important reason, together with a low absorbed dose rate, but the knowledge of microsphere distributions is limited.

  4. 2. Small-scale dosimetry methods for normal tissues after radioembolization and peptide receptor radiotherapies; a focus on the liver parenchyma and the bone marrow

    Author : Jens Hemmingsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dosimetry; Radioembolization; PRRT; lutetium-177; terbium-161; yttrium-90;

    Abstract : Radionuclide therapies are increasingly used in cancer treatments as they have been proven to be both effective and safe. As biodistributions and uptake vary widely between patients, a standardized approach is bound to leave a fraction of patients overtreated or undertreated. READ MORE
