    Sammanfattning : Prostate cancer is a large and increasing medical problem both in Sweden and in the rest of the developed world, with about 300.000 new cases diagnosed world wide annually. Despite the high incidence of this disease, little is known about the aetiology of prostate cancer. LÄS MER

  5. 4. Tissue Doppler in Spectral and Color ModeMethodological ConsiderationsNon-invasive Estimation of Left Ventricular Filling Pressures using the E/Em index

    Författare :Aristomenis Manouras; Lars Åke Brodin; Michael Henein; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue Doppler; Cardiology; Kardiologi;

    Sammanfattning : Aims: Tissue Doppler (TD) in spectral mode (spectral TD) and color TD are the two modalities available today in tissue velocity echocardiography (TVE). Measurements of left ventricular (LV) myocardial velocities and displacement may yield different results depending on the employed sonographic modality and the subjective adjustments during data analysis.

  7. 5. Quantitative Imaging-Biomarker in Prostate Cancer. Validation of Automated Bone Scan Index in the Context of Radiographic Disease Progression in Metastatic Castration Resistant Prostate Cancer

    Författare :Aseem Undvall Anand; Malmö Urologisk cancerforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Background: Metastatic castration resistant prostate cancer (mCRPC) is a bone dominant lethal disease. Progression in bone scan of mCRPC disease is assessed with the Prostate Cancer Working Group (PCWG) two and three criteria, which relies on the appearance of two or more new lesions. LÄS MER
