  2. 1. Brain Tumor Imaging and Treatment Effects. Imaging findings and cognitive function in glioblastoma patients

    Author : Anna Rydelius; Lund Neurologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioblastoma; Imaging finding; Quantitative volumetry; Cognitive function; Diffusion tensor imaging DTI ; Treatment effect; Radiotherapy; VMAT; Parametric response maps PRM ; Treatment responce prediction;

    Abstract : AbstractBackground: Glioblastoma is the most common malignant brain tumor. Operation with maximal resection, if feasible, otherwise biopsy followed by radiotherapy and chemotherapy with temozolomide is standard therapy. The prognosis remains poor, with median overall survival being 15 months despite therapy. READ MORE

  4. 2. Theranostics in Neuroendocrine Tumors : Somatostatin Receptor Imaging and Therapy

    Author : Ezgi Ilan; Mark Lubberink; Peter Bernhardt; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 177Lu-DOTATATE; 68Ga-DOTATATE; 68Ga-DOTATOC; PRRT; Theranostics; PET CT; SPECT CT; Neuroendocrine tumors; Somatostatin receptors; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : Neuroendocrine tumors (NETs) are characterized by cellular overexpression of somatostatin receptors (SSTR), which allows for the use of radiolabeled somatostatin analogs (SSA) for both imaging and therapy. Because NETs often are diagnosed at a metastatic stage, curative surgery is not possible. READ MORE

  5. 3. Towards Clinical Implementation of Dynamic Positron Emission Tomography in Neurodegenerative Diseases

    Author : My Jonasson; Mark Lubberink; Lieuwe Appel; Jens Sörensen; Michel Koole; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography; PET; Molecular imaging; Quantification; Kinetic modelling; Parametric images; Alzheimer’s disease; Parkinson’s disease; Radiology; Radiologi;

    Abstract : Alzheimer’s disease (AD) and Parkinson’s disease (PD) are the two most common neurodegenerative disorders worldwide. Positron emission tomography (PET), together with suitable biomarkers, can aid in the clin-ical evaluation as well as in research investigations of these diseases. READ MORE

  6. 4. Quantitative methods for tumor imaging with dynamic PET

    Author : Ida Häggström; Anne Larsson; Mikael Karlsson; Lennart Johansson; Jens Sörensen; Magnus Dahlbom; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Dynamic positron emission tomography; PET; tumor imaging; compartment modeling; Monte Carlo; radiofysik; radiation physics;

    Abstract : There is always a need and drive to improve modern cancer care. Dynamic positron emission tomography (PET) offers the advantage of in vivo functional imaging, combined with the ability to follow the physiological processes over time. READ MORE

  7. 5. Decoding the complex brain : multivariate and multimodal analyses of neuroimaging data

    Author : Alireza Salami; Lars Nyberg; Cheryl Grady; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multivariate analysis; univariate analysis; multimodal imaging; episodic memory; aging; functional magnetic resonance imaging; diffusion tensor imaging; biology; biologi; Psychology; psykologi; datoriserad bildanalys; Computerized Image Analysis;

    Abstract : Functional brain images are extraordinarily rich data sets that reveal distributed brain networks engaged in a wide variety of cognitive operations. It is a substantial challenge both to create models of cognition that mimic behavior and underlying cognitive processes and to choose a suitable analytic method to identify underlying brain networks.
