    Abstract : A few abnormal cells found in a small piece of prostate tissue are most consequential for a man’s future. The prevalence of prostate cancer (PCa) is increasing globally. READ MORE

  2. 12. Magnetic Resonance Imaging in Legg-Calvé-Perthes Disease

    University dissertation from Department of Radiology, Lund University

    Author : Peter Hochbergs; [1998]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Clinical physics; Histology; Metaphysis; Synovitis; Necrosis; Osteotomy; Arthrography; Magnetic Resonance Imaging; Legg-Calvé-Perthes Disease; Pediatrics; Hip; medicinsk instrumentering; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology;

    Abstract : The aims of this study were: to compare the cartilaginous outline of the femoral head obtained on arthrograms with those on MR images and to correlate it to the bony head outlines on conventional radiograps; to study early, postoperative cartilaginous and bony remodeling of the femoral head, after proximal femoral varus derotation extension osteotomy, with MR imaging and conventional radiography; to describe signal abnormalities on MR images in the femoral epiphysis, their location, extent and restitution over time; to evaluate the degree and persistence of synovitis in the hip joint by MR imaging; to analyze the metaphyseal histology and to correlate it to the signal intensity on the MR images in the corresponding biopsy region. Results and conclusions: MR imaging and arthrography define the shape of the femoral head cartilage equally well. READ MORE

  3. 13. Double-contrast MRI for the staging of rectal carcinoma: Technical aspects and clinical experience

    University dissertation from Department of Radiology, Lund University

    Author : Nils-Olof Wallengren; [2001]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; Double contrast; MR imaging; Preoperative staging; Rectal carcinoma; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Abstract : Aim of the study Today´s methods for the staging of rectal carcinoma: ultrasonography with transrectal probe, CT, MRI or MRI with a rectal coil, all have limitations. The aim was therefore to develop a new, double-contrast MRI method for evaluation of rectal carcinoma. READ MORE

  4. 14. Gadodiamide injection for Enhancement of MRI in the CNS. Applications, dose, field and time dependence

    University dissertation from Department of Radiology, Lund University
