  1. 1. Deriving biomarkers from computed tomography using deep learning

    Författare :Meera Srikrishna; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; CT; MRI; convoluted neural networks; deep learning; Dementia; Alzheimer s disease; Normal pressure hydrocephalus; brain segmentation;

    Sammanfattning : X-ray computed tomography (CT) and magnetic resonance imaging (MRI) are widely used structural neuroimaging modalities. For brain atrophy assessment and volumetric quantification using automated methods, MRI is the preferred modality due to its superior soft tissue contrast. LÄS MER

  3. 2. Magnetic Resonance Imaging in Parkinsons's disease and related disoders

    Författare :Yulia Surova; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mr Imaging; DTI; Parkinson s disease; Progressive supranuclear palsy; Multiple system atrophy;

    Sammanfattning : Objectives: To identify diagnostic and prognostic biomarkers in the cerebral white (WM) and the deep grey matter (GM) in patients with Parkinson’s disease (PD) and atypical parkinsonian syndromes (APS) using magnetic resonance imaging (MRI). Methods: Patients with a clinical diagnosis of PD, multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) were included in the study. LÄS MER

  4. 3. Refractory angina pectoris. Patient characteristics, safety and long-term effects of spinal cord stimulation

    Författare :Paulin Andréll; Göteborgs universitet; []
    Nyckelord :Angina pectoris; Deep white matter disease; Epidemiology; Health care costs; Morbidity; Mortality; Quality of life; Spinal cord stimulation;

    Sammanfattning : Refractory angina pectoris has been defined as severe angina pectoris due to coronary artery disease which cannot be controlled by conventional pharmacological or surgical therapy. The epidemiology of this condition is virtually unknown. During the last decades, additional treatment options have been developed for this condition. LÄS MER

  5. 4. Magnetic resonance imaging in dementia : a study of brain white matter changes

    Författare :Lena Bronge; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Non-specific white matter changes (WMC) in the brain are common findings in the elderly population. Although they are frequently seen in non-demented persons, WMC seem to be more common in demented patients.The significance of these changes, as well as their pathophysiological background is incompletely understood.

  7. 5. Cerebral microbleeds and cognitive impairment

    Författare :Sara Shams; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: With increasingly ageing populations comes an increased prevalence of cognitive impairment and dementia. The pathophysiology behind dementia is still unknown, and there is no cure. LÄS MER
