  1. 1. Assessment of skeletal structure by MR relaxometry

    Författare :Torkel B Brismar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :magnetic resonance imaging; bone and bones; osteoporosis;

    Sammanfattning : Introduction: More than 40 per cent of all women older than 50 years will suffer from a hip, wrist or vertebral fracture. Most of these fractures are related to bone fragility, osteoporosis. If the disease is diagnosed and treated at an early stage the risk of fracture can be decreased. LÄS MER

  3. 2. Radiological measurements in total hip arthroplasty

    Författare :Bariq Al-Amiry; Arkan Sayed-Noor; Torkel Brismar; Seppo Koskinen; Mats Geijer; Umeå universitet; []
    Nyckelord :Total hip arthroplasty; leg length discrepancy; femoral offset; WOMAC; quality of life; radiographicmeasurements; Kellgren-Lawrence; duration; acetabular cup; inclination; anteversion; BMI;

    Sammanfattning : Every year, about 1 million patients worldwide and 20000 patients in Sweden undergo total hip arthroplasty (THA). This type of operation is considered a successful, safe and cost-effective procedure to regain mobility and restore hip joint function in patients suffering from severe hip joint disease or trauma.

  4. 3. Magnetic Resonance Imaging of the Hepatobiliary System Using Hepatocyte-Specific Contrast Media

    Författare :Nils Dahlström; Örjan Smedby; Torkel Brismar; Anders Ynnerman; Lennart Blomqvist; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Diagnostic radiology; Diagnostisk radiologi;

    Sammanfattning : There are two Gadolinium-based liver-specific contrast media for Magnetic Resonance Imaging on the market, Gd-BOPTA (MultiHance®, Bracco Imaging, Milan, Italy) and Gd-EOB-DTPA (Primovist®, Bayer Schering Pharma, Berlin, Germany). The aim of this study in two parts was to evaluate the dynamics of biliary, parenchymal and vascular enhancement using these contrast media in healthy subjects. LÄS MER

  5. 4. Quantitative Evaluation of Contrast Agent Dynamics in Liver MRI

    Författare :Nils Dahlström; Örjan Smedby; Torkel Brismar; Anders Ynnerman; Carsten Thomsen; Linköpings universitet; []
    Nyckelord :Liver; spleen; hepatobiliary system; liver function; MRI; DCE-MRI; Gd-EOBDTPA; Gd-BOPTA; pharmacokinetic; hepatocyte; relaxivity.; MEDICINE; MEDICIN;

    Sammanfattning : The studies presented here evaluate the biliary, parenchymal and vascular enhancement effects of two T1-shortening liver-specific contrast agents, Gd-BOPTA and Gd-EOB-DTPA, in Magnetic Resonance Imaging (MRI) of healthy subjects and of patients.Ten healthy volunteers were examined with both contrast agents in a 1.

  7. 5. Image Analysis for Trabecular Bone Properties on Cone-Beam CT Data

    Författare :Eva Klintström; Örjan Smedby; Rodrigo Moren; Torkel Brismar; Dan Mellström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Trabecular bone structure as well as bone mineral density (BMD) have impact on the biomechanical competence of bone. In osteoporosis-related fractures, there have been shown to exist disconnections in the trabecular network as well as low bone mineral density. Imaging of bone parameters is therefore of importance in detecting osteoporosis. LÄS MER
