1. 11. Quantitative evaluation of liver function using gadoxetic acid-enhanced MRI

   Författare :Qiang Wang; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Before liver resection, a reliable and accurate assessment of the liver function is essential to ensure a safe surgery and avoid unfavorable complications such as post-hepatectomy liver failure (PHLF). Gadoxetic acid enhanced magnetic resonance imaging (MRI) is a routinely used imaging modality for tumor detection and characterization. LÄS MER

3. 12. Magnetic resonance imaging for the assessment of liver function

   Författare :Henrik Nilsson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :DHCE-MRI;

   Sammanfattning : This thesis presents dynamic hepatocyte-specific contrast-enhanced magnetic resonance imaging (DHCE-MRI) as a new method for total and segmental liver function assessment. The method is based on the hepatocyte-specific properties of Gd- EOB-DTPA, which is actively taken up into functioning hepatocytes. LÄS MER

4. 13. Perfusion MRI of the brain after radiotherapy in patients with glioblastoma – potential and problems

   Författare :Markus Fahlström; Elna-Marie Larsson; Tufve Nyholm; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : Perfusion Magnetic Resonance Imaging (MRI) is a useful tool in diagnostic evaluation and treatment response assessment in patients with glioblastoma. The standard treatment regimen includes surgical resection, radiotherapy and adjuvant chemotherapy. However, prognosis is poor; relative 5-year survival is 3–5%. LÄS MER

5. 14. Dynamic magnetic resonance imaging of the breast : imaging features for diagnosis and prognosis of breast cancer

   Författare :Botond K Szabo; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Breast neoplasm; magnetic resonance imaging; prognostic factors; survival analysis; image segmentation; artificial neural networks;

   Sammanfattning : The general aim of the present thesis was to identify and study dynamic contrast-enhanced magnetic resonance imaging (CE-MRI) features that contribute to the diagnosis and may help in predicting prognosis in breast cancer. Study I studied the kinetic and morphological MR features and their diagnostic power were studied in a total of 92 women with 109 histopathologically verified breast lesions. LÄS MER

7. 15. Magnetic resonance imaging in breast diagnosis

   Författare :Maria Kristoffersen Wiberg; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :MRI; breast; triple diagnosis; FNAB; size; scintimammography.;

   Sammanfattning : MRI of the breast has, since the introduction of gadolinium contrast agents, been increasingly used in breast investigations. MRI has been found to have a high sensitivity but a low specificity in cancer detection. The aim of this thesis was to study and establish the role of MRI in the clinical diagnosis of breast lesions.
