  2. 1. Cerebral blood flow distribution, collateral function and pulsatility in healthy and in patients with symptomatic carotid stenosis  : a magnetic resonance imaging approach

    Author : Laleh Zarrinkoob; Jan Malm; Anders Eklund; Khalid Ambarki; Sepideh Amin-Hanjani; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aging; Arterial pulsatility; Carotid stenosis; Cerebral arteries; Cerebral blood flow; Cerebral collateral blood flow; Circle of Willis; Phase contrast magnetic resonance imaging;

    Abstract : Background: For the detection and treatment of early cerebral vascular disease it is of paramount importance to first understand the normal physiology of the cerebral vasculature, and subsequently, to understand how and when pathology can develop from that. This is especially important as the population above 65 years of age is increasing and aging itself is an established risk factor for the development of cerebral vascular disease. READ MORE

  4. 2. In Vivo Evaluation of Skeletal Muscle Morphological and Mechanical Properties using Medical Imaging

    Abstract : Skeletal muscles are soft tissues that play an important role in maintaining body posture and enabling movements through force generation. The force-generating capacity is associated with the morphological and mechanical properties of the muscle. READ MORE

  5. 3. 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

  6. 4. Magnetic Resonance Imaging in Parkinsons's disease and related disoders

    Author : Yulia Surova; Lund Neurologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mr Imaging; DTI; Parkinson s disease; Progressive supranuclear palsy; Multiple system atrophy;

    Abstract : Objectives: To identify diagnostic and prognostic biomarkers in the cerebral white (WM) and the deep grey matter (GM) in patients with Parkinson’s disease (PD) and atypical parkinsonian syndromes (APS) using magnetic resonance imaging (MRI). Methods: Patients with a clinical diagnosis of PD, multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) were included in the study. READ MORE

  7. 5. The Temporomandibular Joint in Juvenile Idiopathic Arthritis : Psychosocial, clinical, imaging and parotid saliva biomarkers

    Author : Alexandra Dimitrijevic Carlsson; Per Alstergren; Kerstin Wahlund; Carin Starkhammar Johansson; Martina. Frodlund; Bijar Ghafouri; Robin Kahn; Malmö universitet; []

    Abstract : Juvenile idiopathic arthritis (JIA) is the most common rheumatic disease in children. The disease can affect the temporomandibular joint (TMJ) and cause orofacial growth disturbances, pain, and jaw dysfunction. TMJ arthritis is often asymptomatic and therefore a challenging joint to diagnose. READ MORE
