  1. 1. Magnetic resonance imaging of rectal tumours

    Författare :Lennart Blomqvist; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Rectum; Neoplasms; Magnetic Resonance Imaging;

    Sammanfattning : Cross sectional imaging techniques introduced during the last two decades have been increasingly used in the evaluation of patients with pelvic tumours. The extent of tumour - the tumour stage - at the time of diagnosis constitutes a guideline for both the immediate treatment and the follow-up of the patient. LÄS MER

  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. MRI Contrast Enhancement and Cell Labeling using Gd2O3 Nanoparticles

    Författare :Anna Hedlund; Maria Engström; Kajsa Uvdal; Örjan Smedby; Lennart Blomqvist; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : There is an increasing interest for nanomaterials in bio-medical applications and in this work, nanoparticles of gadolinium oxide (Gd2O3 ) have been investigated as a novel contrast agent for magnetic resonance imaging (MRI). Relaxation properties have been studied in aqueous solutions as well as in cell culture medium and the nanoparticles have been explored as cell labeling agents. LÄS MER

  7. 5. Whole-Body MRI including Diffusion-Weighted Imaging in Oncology

    Författare :Firas Mosavi; Håkan Ahlström; Lennart Blomqvist; Uppsala universitet; []
    Nyckelord :Diffusion-weighted imaging; Whole-body MRI; NaF PET CT; FDG PE CT; apparent diffusion coefficient;

    Sammanfattning : Cancer is one of the major causes of worldwide mortality. Imaging plays a vital role in the staging, follow-up, and evaluation of therapeutic response in cancer patients. Whole-body (WB) magnetic resonance imaging (MRI), as a non-ionizing imaging technique, is a promising procedure to assess tumor spreading in a single examination. LÄS MER
