  3. 3. Superparamagnetic iron oxide nanoparticles (SPIONs) as a multimodality imaging probe for sentinel nodes : Design and Preclinical Evaluation

    Detta är en avhandling från Lund University, Faculty of Science, Department of Medical Radiation Physics

    Författare :Renata Madru; Lund University.; Lunds universitet.; Lund University.; Lunds universitet.; [2018-04]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; iron oxide; nanoparticles; SPIONs; PET-MRI; SPECT-MRI; SPECT-MRI- optical imaging; sentinel lymph node; SNL;

    Sammanfattning : Breast cancer and malignant melanoma disseminate through the lymphatic system and the first metastases arise in one or two regional, sentinel lymph nodes (SLNs) draining the primary tumour site. Therefore, identification and characterization of the SLNs is of major importance for cancer staging and for choice of therapy in patients. LÄS MER
