   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
