11. Head and Neck Cancer: Studies on microvessel density, radiation response and FDG PET
Sammanfattning : Treatment options of head and neck squamous cell carcinoma (HNSCC) usually include combinations of radiotherapy and surgery, and in some cases addition of chemotherapy. In locally advanced cases cure rates are low. Current prognostic factors cannot foresee the outcome for the individual patient. LÄS MER
12. Superparamagnetic iron oxide nanoparticles (SPIONs) as a multimodality imaging probe for sentinel nodes : Design and Preclinical Evaluation
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
13. On potentials and limitations of perfusion MRI in neurological disorders
Sammanfattning : Cerebral perfusion outlines several parameters which describe the status of cerebral haemodynamics. Numerous neurological diseases affect cerebral perfusion, thus the importance of diagnostic measurements. LÄS MER
14. Quality assurance for magnetic resonance imaging (MRI) in radiotherapy
Sammanfattning : Magnetic resonance imaging (MRI) utilizes the magnetic properties of tissues to generate image-forming signals. MRI has exquisite soft-tissue contrast and since tumors are mainly soft-tissues, it offers improved delineation of the target volume and nearby organs at risk. LÄS MER
15. Catecholaminergic neurotransmission in heart and brain : development of tracers for positron emission tomography
Sammanfattning : The catecholamines norepinephrine and its biosynthetic precursor dopamine are two principal neurotransmitters in the human central nervous system (CNS). Moreover, norepinephrine is a major transmitter substance in the peripheral, autonomic nervous system. LÄS MER
