1. 1. 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.

3. 2. Comparison of stereotactic fine needle aspiration biopsy and core needle biopsy in breast lesions

   Författare :Karin Leifland; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Purpose: The purpose of this study was to evaluate the diagnostic value of two biopsy methods by comparing stereotactic fine needle aspiration biopsy (S-FNAB) with stereotactic core needle biopsy (S-CNB). The biopsies were performed by the same radiologist, in the same breast lesion on the same occasion, in order to establish which method that best can be recommended in different kind of mammographically detected lesions.

4. 3. Imaging of soft tissue tumors

   Författare :Hildur Einarsdóttir; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The aim of this project on soft tissue tumors, was to evaluate existing imaging methods and test new Magnetic Resonance Imaging (MRI) sequences for diagnosis and assessment of cytotoxic therapy and to relate the imaging studies to cytology to explore the limitations of each procedure. Patients and method: The studies were based on patients with a soft tissue lesion diagnosed and treated at the Orthopedic Tumor Service at the Karolinska Hospital 1990-2003. LÄS MER

5. 4. Metastatic bone disease

   Författare :Rikard Wedin; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :cytology; epidemiology; metastatic bone disease; pathologic fracture; prognosis; radiotherapy; skeletal metastasis; surgical therapy; survival; MIB; p53; ER; PgR;

   Sammanfattning : Aim: To evaluate epidemiology, prognosis and diagnostics in metastatic bone disease and identify risk factors for failure after operation for pathologic fracture. Patients: The study was based on patients treated for skeletal metastases, myeloma or lymphoma between 1986 and 1998 at the Oncology Service, Department of Orthopedics, Karolinska Hospital and on patients diagnosed with symptomatic skeletal metastases 1989-1994 in the Stockholm Region.

7. 5. Assessment of diagnostic and prognostic factors in pancreatic duct carcinoma

   Författare :Stefan Linder; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Pancreatic neoplasms; cytology; diagnosis; prognosis; DNA ploidy; morphometry; immunohistochemistry; Ki-67 antigen; p53 protein; ECM proteins; adhesion molecules.;

   Sammanfattning : The diagnosis pancreatic carcinoma is suggested by a combination of clinical and radiological signs. The differential diagnosis vs. chronic pancreatitis may, however, be difficult. Morphological verification of malignancy is therefore necessary before initiating non-surgical therapy. LÄS MER
