2. 1. Evaluation of Intracranial Arteriovenous Malformations with Magnetic Resonance Imaging

   Author : Maria Correia de Verdier; Johan Wikström; Elisabeth Ronne-Engström; Ljubisa Borota; Johan Wassélius; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arteriovenous malformation; brain; proton-radiation therapy; magnetic resonance imaging; phase-contrast MRI; Radiology; Radiologi;

   Abstract : Intracranial arteriovenous malformations (AVMs) are characterized by feeding arteries, a tangle of abnormal vessels (nidus) and draining veins. Radiological evaluation methods are used in diagnosing AVMs, treatment planning, post-treatment evaluation and monitoring stability. READ MORE

5. 3. Implementation of MRI gel dosimetry in radiation therapy

   Author : Sven Bäck; Malmö Medicinsk strålningsfysik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; uncertainty; detector; dosimeter; ferrous ions; gel dosimetry; magnetic resonance imaging; monomers; polymerisation; proton; treatment planning verification; radiation therapy; cancerology; Cytologi; onkologi; cancer;

   Abstract : Gel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. READ MORE

6. 4. Preeclampsia and the Brain : Epidemiological and Magnetic Resonance Studies

   Author : Maria Nelander; Johan Wikström; Anna-Karin Wikström; Inger Sundström Poromaa; Gerda Zeeman; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; preeclampsia; eclampsia; seizure; MRI; MRS; IVIM; dementia; cardiovascular disease; magnesium; cerebral organic osmolytes; perfusion; Obstetrik och gynekologi; Obstetrics and Gynaecology;

   Abstract : Preeclampsia is a pregnancy specific syndrome that causes substantial maternal and fetal morbidity and mortality. One major contributor to maternal deaths is eclampsia, i.e. when seizures arise in the context of preeclampsia. READ MORE

7. 5. Quantitative Magnetic Resonance Imaging of the Brain : Applications for Tissue Segmentation and Multiple Sclerosis

   Author : Janne West; Peter Lundberg; Anne-Marie Landtblom; Marcel Jan Bertus Warntjes; Örjan Smedby; Olof Dahlqvist Leinhard; Per Thunberg; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Magnetic resonance imaging (MRI) is a sensitive technique for assessing white matter (WM) lesions in multiple sclerosis (MS), but there is a low correlation between MRI findings and clinical disability. Because of this, other pathological changes are of interest, including changes in normal appearing white matter (NAWM) and diffusely abnormal white matter (DAWM). READ MORE
