    Sammanfattning : Computed tomography urography (CTU) is today the imaging method used to investigate patients with suspected urinary tract malignancy, replacing the old imaging method intravenous pyelography (IVP) about a decade ago. The downside of this shift was that the effective radiation dose to the examined patient was eight times higher for CTU compared to IVP. LÄS MER

    Sammanfattning : Stress has emerged as one of the most important factors to consider in psychiatric diagnoses and has become a common reason for long-term sick leave (LTSL). Roughly 50% of LTSL due to psychiatric diseases are thought to be associated with work-related stress. LÄS MER

    Sammanfattning : 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. LÄS MER

  5. 5. MRI at 3 T of brain functions and fibre tracts adjacent to intracranial tumors

    Detta är en avhandling från Diagnostisk radiologi, Lunds Universitet

    Författare :Danielle van Westen; [2006]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; radiology; tomography; Clinical physics; Medicin människa och djur ; Medicine human and vertebrates ; somatosensory cortex; diffusion magnetic resonance imaging; neoplasms; Functional Magnetic Resonance Imaging;

    Sammanfattning : The aims of the studies were: to evaluate the spatial resolution of fMRI at 3 T by studying fingersomatotopy in area 3 b of the primary sensory area (Paper 1); to investigate the potential of fMRI at 3T as a clinical tool for preoperative evaluation of patients with intracranial tumors (Paper 2); to investigate the effect of glioma resection on the spatial extent of fMRI activation as compared to the normal within-subject variability (Paper 3); to determine whether the apparent diffusion coefficient (ADC) and fractional anisotropy (FA) can distinguish tumor-infiltrated edema of gliomas from pure edema of meningiomas and metastases (Paper 4). Results: Strict somatotopic organisation in the primary sensory cortex was shown in the group average; at the subject level the thumb was located laterally, anteriorly and inferiorly to the little finger in 94 % of subjects (Paper 1).
