  2. 1. Physical Modeling of Brain and Head Kinematics

    Author : Johan Ivarsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; brain injury; skull base; rotational acceleration; physical models; lateral ventricles; head kinematics; padding materials; sulci; free motion headform; brain kinematics;

    Abstract : The development of head injury criteria and countermeasures for head protection requires understanding of how different factors affect brain and head kinematics. In this thesis, 2D physical models of the human head were developed and used to evaluate how various factors affect brain kinematics during angular head kinematics. READ MORE

  4. 2. Three-dimensional assessment of cardiac function; When right is wrong

    Author : Ellen Ostenfeld; Lund Klinisk fysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Key words Three-dimensional echocardiography; cardiac magnetic resonance imaging; cardiac function; volumes; atria; ventricles; pulmonary hypertension; right heart catheterization; right ventricular pressure load.;

    Abstract : Assessment of the right side of the heart is important in patients with heart disease; especially in patient with elevated pressure in the lung circulation. Decreased right ventricular function and elevated pressure in the right atrium are of poor prognostic value. READ MORE

  6. 4. Brain imaging in preterm infants at term equivalent age : value and comparison of MRI and ultrasound

    Author : Sandra Horsch; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Cranial ultrasound (cUS) and magnetic resonance imaging (MRI) are the two most commonly used brain imaging techniques in preterm infants. cUS can be performed at the bedside and detects all major brain abnormalities (haemorrhages, infarctions, cysts, dilatation of the lateral ventricles) that are associated with severe neurodevelopmental disability.

  7. 5. Idiopathic Normal Pressure Hydrocephalus : Cerebrospinal Fluid Tap Test and Magnetic Resonance Imaging as Preoperative Prognostic Investigations

    Author : Johan Virhammar; Elna-Marie Larsson; Katarina Laurell; Kristina Giuliana Cesarini; Magnus Tisell; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; normal pressure hydrocephalus; NPH; cerebrospinal fluid disorders; dementia; MRI; CSF tap test; CBF; ASL; Neurology; Neurologi; Neurosurgery; Neurokirurgi; Radiologi; Radiology;

    Abstract : Idiopathic normal pressure hydrocephalus (iNPH) is a condition with dilated cerebral ventricles but intracranial pressure within normal limits. The symptoms of gait impairment, cognitive decline and urinary incontinence develop gradually. Treatment with shunt insertion results in improvement in eight out of ten patients. READ MORE
