2. 6. Preoperative MRI and PET in suspected low-grade gliomas : Radiological, neuropathological and clinical intersections

   Author : Anna Falk Delgado; Elna-Marie Larsson; Anja Smits; Jens Sörensen; John Hald; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Low-grade glioma; MRI; PET; FA; MD; Perfusion; Diffusion; Neuropathology; Oligodendroglioma; Astrocytoma; PET; tractography; DTI; DTT; Radiologi; Radiology;

   Abstract : Background: Gliomas are neuroepithelial tumours classified by cell type and grade. In adults, low-grade gliomas are comprised mainly of astrocytomas and oligodendrogliomas grade II. READ MORE

4. 7. 177Lu-DOTA-octreotate Radionuclide Therapy of Neuroendocrine Tumours : Dosimetry-Based Therapy Planning and Outcome

   Author : Ulrike Garske-Román; Barbro Eriksson; Anders Sundin; Jens Sörensen; Dik Kwekkeboom; Uppsala universitet; []
   Keywords : ;

   Abstract : Peptide receptor radionuclide therapy for the internal radiation of neuroendocrine tumours expressing somatostatin receptors has made great advances and offers promising results. 177Lu-DOTA-octreotate is one of the most widely used radiopeptides, but kidneys and bone marrow are organs at risk.

5. 8. Characterization of [18F]flutemetamol binding properties : A β-amyloid PET imaging ligand

   Author : Kerstin Heurling; Mark Lubberink; Jens Sörensen; Julie Price; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Positron emission tomography PET ; molecular imaging; amyloid; tracer validation; Radiology; Radiologi;

   Abstract : The criteria for diagnosing Alzheimer’s disease (AD) have recently been revised to include the use of biomarkers for the in vivo presence of β-amyloid, one of the neuropathological hallmarks of AD. Examples of such biomarkers are positron emission tomography (PET) β-amyloid specific ligands, including [18F]flutemetamol. READ MORE

6. 9. 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. 10. 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
