  1. 1. Preprocessing for intravoxel incoherent motion analysis in the brain - Signal drift correction

    University essay from

    Author : Amina Warsame; [2023-04-17]
    Keywords : Medical physics; Diffusion magnetic resonance imaging; dMRI; Intravoxel incoherent motion; IVIM;

    Abstract : Diffusion magnetic resonance imaging (dMRI) is a diagnostic imaging technique that is sensitized to the movement of water molecules in tissues. Intravoxel incoherent motion (IVIM) analysis can be used to estimate blood flow in capillaries from weakly diffusion-weighted data. READ MORE

  3. 2. Optimization of b-value Acquisition and Parameter Estimation of Intravoxel Incoherent Motion Measurements

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Ivan Rashid; [2023]
    Keywords : Medicine and Health Sciences;

    Abstract : Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. READ MORE

  4. 3. Deep Neural Networks for Noise Reduction and Bias Removal in MR Diffusion Signal

    University essay from

    Author : Beqir Berisha; [2022-03-22]
    Keywords : Medical physics; Deep Neural network; Prostate cancer; noise; Diffusion-weighted imaging; Rician bias correction;

    Abstract : The purpose of this study is to assess the potential of deep neural networks, trained by unsupervised learning, for diffusion weighted imaging (DWI) data modeling and denoising. DWI data were modeled by a biexponential model and Rician bias was corrected for. READ MORE

  5. 4. The adolescent brain on social-media : A systematic review

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Michaela Åström; [2021]
    Keywords : Adolescence; neuroimaging; social brain; social rewards; social-media use SMU ;

    Abstract : Adolescence is an exceptional period of life, not least in terms of social and brain development. Friends become increasingly important, susceptibility to peer rejection increases, and brain regions involved in social cognition are predicted to go through major changes. READ MORE

  6. 5. Towards non-invasive Gleason grading of prostate cancer using diffusion weighted MRI

    University essay from Umeå universitet/Institutionen för fysik

    Author : Pierre Hillergren; [2020]
    Keywords : ;

    Abstract : Prostate cancer is one of the most common cancer diagnosis in men. This project aimed to help in characterization and treatment planning of prostate cancer by producing a Gleason grading probability based on apparent diffusion coefficient (ADC). READ MORE
