  1. 1. Simulation supported training in oral radiology methods and impact on interpretative skill

    Detta är en avhandling från Umeå : Odontologi

    Författare :Tore Nilsson; Jan Ahlqvist; Martin Rydmark; [2007]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virtual reality; simulation; simulator; radiology; radiography; learning; skill acquisition; visual-spatial ability; parallax; MEDICINE Physiology and pharmacology Radiological research Radiology; MEDICIN Fysiologi och farmakologi Radiologisk forskning Radiologi; odontologi; Odontology;

    Sammanfattning : Simulation is an important tool when training is hazardous, time consuming, or expensive. Simulation can also be used to enhance reality by adding features normally not available in the real world. LÄS MER

  2. 2. Quantification of Arterial Wall with MRI and Image Processing

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Mari Hänni; Torbjörn Andersson; [2002]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; image processing; Magnetic resonance imaging; animal model; arterial wall; Radiologisk forskning; atherosclerosis; MEDICINE Physiology and pharmacology Radiological research; MEDICIN Fysiologi och farmakologi Radiologisk forskning; Diagnostisk radiologi; Diagnostic Radiology;

    Sammanfattning : Quantification of atherosclerosis in vivo in animal models is of great importance when treatments against atherosclerosis are evaluated. In the studies presented in this thesis a non-invasive method combining MRI and image processing is evaluated. LÄS MER

  3. 3. Imaging the tumor microenvironment the dynamics and modification of hypoxia

    Detta är en avhandling från Umeå : Strålningsvetenskaper

    Författare :Anna Ljungkvist; Peggy L. Olive; [2003]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; tumor microenvironment; double hypoxic marker method; proliferation; hypoxia; hypoxic half-life; Radiologisk forskning; MEDICINE Physiology and pharmacology Radiological research; MEDICIN Fysiologi och farmakologi Radiologisk forskning; diagnostisk radiologi; Diagnostic Radiology;

    Sammanfattning : The tumor vasculature is poor and heterogeneous which may result in inadequate oxygenation and changed energy status. In addition the balance between cell proliferation and the rate of cell death is disturbed, which results in tumor growth. LÄS MER

  4. 4. Transjugular intrahepatic portosystemic shunt in the treatment of symptomatic portal hypertension

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Kerstin Rosenqvist; Rickard Nyman; Charlotte Ebeling Barbier; Fredrik Rorsman; Lars-Gunnar Eriksson; Lars Lönn; [2017]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Portal hypertension; TIPS; transjugular; portal venous thrombosis; mesenteric venous thrombosis; liver cirrhosis; interventional radiology; Radiology; Radiologi;

    Sammanfattning : Portal hypertension (PHT) is a condition with serious complications, such as variceal bleeding, refractory ascites and bowel ischemia. The cause of PHT may be pre-, intra- or post-hepatic. Initial treatment is pressure-reducing drugs and the treatment of acute symptoms. LÄS MER

  5. 5. Nuclear magnetic resonance and microcirculation: The influence of pulsatile brain-tissue motion on measurements of intravoxel incoherent motion and assessment of haemodynamics using exo- and endogenous tracers

    Detta är en avhandling från Radiation Physics, Lund

    Författare :Ronnie Wirestam; [1997]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diagnostic radiology; cortical activation; diffusion; tumor; tumour; ischemic stroke; ischaemic stroke; tracer kinetics; bolus tracking; phase mapping; brain motion; intracranial dynamics; blood flow; haemodynamics; vascularity; MRS; perfusion; MRI; magnetic resonance; Clinical physics; radiology; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : In this project, the potential of magnetic resonance (MR) imaging and spectroscopy in studies of microcirculation and haemodynamics was evaluated. The spatial and temporal characteristics of human pulsatile brain-tissue movements in healthy individuals, relevant for the understanding of the cerebrospinal-fluid (CSF) circulation and the pathogenesis of hydrocephalus, were thoroughly investigated.
