  1. 11. Deep Learning for the prediction of RASER-MRI profiles

    University essay from Linköpings universitet/Medie- och Informationsteknik

    Author : Filip Arvidsson; Jonas Bertilson; [2023]
    Keywords : MRI; NMR; AI; Deep Learning; RASER-MRI; Media Technology; KIT; LIU; CNN; Autoencoder; Djupinlärning; Medieteknik; Magnetröntgen;

    Abstract : Magnetic resonance imaging (MRI) is a critical diagnostic tool in medical practice, enabling non-invasive visualization of anatomy and physiological processes. Nonetheless, MRI has inherent spatial resolution limitations, which may limit its diagnostic capabilities. READ MORE

  3. 12. Phase Unwrapping MRI Flow Measurements

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Mio Liljeblad; [2023]
    Keywords : phase unwrapping; computer vision; cine MRI; NMR; flow measurements; velocity encoding; venc; energy minimization; magnetic resonance; cardiac MRI; sinotubuar junction; pulmonary artery; ascending descending aorta; laplacian algorithm; iterative graph cuts; IGC; sequential tree-reweighted message passing; TRW-S; velocity to noise ratio; VNR; retrospective wrapping; energy formulation;

    Abstract : Magnetic resonance images (MRI) are acquired by sampling the current of induced electromotiveforce (EMF). EMF is induced due to flux of the net magnetic field from coherent nuclear spins with intrinsic magnetic dipole moments. READ MORE

  4. 13. Psilocybin Induced Psychedelic Experiences : their Neural Mechanisms and Efficacy for Treating Depressive Disorders

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Linda Lindecrantz; Nicklas Villman; [2023]
    Keywords : psilocybin; depression; fMRI; systematic review; DMN;

    Abstract : The aim of this systematic review is to present the current literature on the therapeutic potential of the classic psychedelic compound psilocybin for depressive disorders and the neurocognitive mechanisms involved recorded with functional magnetic resonance imaging (fMRI). A comprehensive literature search was conducted in the electronic databases Web of Science, Scopus and Medline EBSCO using a Boolean search string containing the keywords psilocybin, depression, fMRI, MRI and PET.

  5. 14. What happens in the brain during adolescence? : A systematic review of gray and white matter changes during adolescence

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Ema Milcendeau; Martina Hana; [2023]
    Keywords : Adolescence; brain development; longitudinal studies; gray and white matter changes; SIPN model; triadic model; synaptic pruning; myelination;

    Abstract : During adolescence, the brain undergoes significant reorganization due to myelination and synaptic pruning. These changes are associated with risk-taking behaviors and the development of social relationships. Recent advancements in adolescent brain development can potentially enhance strategies for preventing and treating mental health disorders. READ MORE

  6. 15. Deep Learning Based Detection, Quantification, and Subdivision of White Matter Hyperintensities in Brain MRI

    University essay from Uppsala universitet/Avdelningen Vi3

    Author : Inna Fryckstedt; [2023]
    Keywords : white matter hyperintensities; white matter lesions; deep learning; machine learning; DL; ML; MRI; iNPH;

    Abstract : White matter hyperintensities (WMH) are commonly found as bright regions in brain MRI images in older individuals. They are associated with various neurological and vascular diseases, such as stroke, dementia, and cardiovascular disorders. READ MORE
