2. 1. Geometric distortions in MRI based radiotherapy and PET/MRI

   Author : Josef Lundman; Tufve Nyholm; Anne Larsson; Jörgen Olofsson; Marco Riboldi; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Magnetic resonance imaging; MRI; PET MR; PET MRI; medical imaging; radiotherapy; geometrical distortions; MR-only; MRI-only; radiofysik; radiation physics;

   Abstract : Magnetic resonance imaging (MRI) offers high soft-tissue contrast compared to computed tomography (CT). This contrast is helpful in many cases, not least for delineating tumours for radiotherapy treatment, and has led to increasing use in radiotherapy treatment planning (RTP). READ MORE

4. 2. Modern multimodal methods in brain MRI

   Author : David Abramian; Anders Eklund; Evren Özarslan; Ida Blystad; Hamid Behjat; Jesper Andersson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Functional MRI; Diffusion MRI; Graph signal processing; Deep learning;

   Abstract : Magnetic resonance imaging (MRI) is one of the pillars of modern medical imaging, providing a non-invasive means to generate 3D images of the body with high soft-tissue contrast. Furthermore, the possibilities afforded by the design of MRI sequences enable the signal to be sensitized to a multitude of physiological tissue properties, resulting in a wide variety of distinct MRI modalities for clinical and research use.

5. 3. Myocardial Scars on MRI : Their Prevalence and Possible Impact

   Author : Charlotte Ebeling Barbier; Håkan Ahlström; Tomas Bjerner; Lars Johansson; Lars Lind; Kirsi Lauerma; Uppsala universitet; []
   Keywords : Radiology; magnetic resonance imaging; myocardial infarction; epidemiology; myocardial infarction; epidemiology; Radiologisk forskning;

   Abstract : Myocardial infarction (MI) causes high morbidity and mortality worldwide and for effective prevention and treatment MIs have to be adequately detected.The existence of clinically unrecognized MIs (UMIs) has been known for the past hundred years, but an ultimate tool for their detection has not yet been found.

6. 4. Quality assurance for magnetic resonance imaging (MRI) in radiotherapy

   Author : Mary Adjeiwaah; Tufve Nyholm; Anders Garpebring; Joakim Jonsson; Sofie Ceberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; MRI; radiotherapy; RT; geometric distortions; magnetic susceptibility; B0 maps; quality assurance; radiofysik; radiation physics;

   Abstract : The use of Magnetic Resonance Imaging (MRI) in the radiotherapy (RT) treatment planning workflow is increasing. MRI offers superior soft-tissue contrast compared to Computed Tomography (CT) and therefore improves the accuracy in target volume definitions. READ MORE

7. 5. Does spinal alignment influence car occupant responses? -The influence of variation in whole spinal alignment patterns on vertebral kinematics under rear impact conditions-

   Author : Fusako Sato Sakayachi; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; neck injury; rear impact; whiplash; occupant; female; cervical vertebral kinematics; MRI; Multi-Dimensional Scaling; automotive seated posture; spinal alignment;

   Abstract : The susceptibility of women to Whiplash Associated Disorders (WADs) has been the focus of numerous epidemiologic studies. Summarising the epidemiologic WAD studies, women were found to be subject to up to three times higher risk of sustaining WADs than men. READ MORE
