  1. 11. Deep Learning-Based Skeleton Segmentation for Analysis of Bone Marrow and Cortical Bone in Water-Fat Magnetic Resonance Imaging

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Adham Belbaisi; [2021]
    Keywords : Water-fat MRI; UK Biobank; Deep learning; Skeleton segmentation; Bone marrow; Cortical bone;

    Abstract : A major health concern for subjects with diabetes is weaker bones and increased fracture risk. Current clinical assessment of the bone strength is performed by measuring Bone Mineral Density (BMD), where low BMD-values are associated with an increased risk of fracture. READ MORE

  3. 12. Black-Blood Phase Contrast Magnetic Resonance Imaging using Stimulated Echo Acquisition Mode : Pulse Sequence Development

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Reenalyn Borromeo; [2020]
    Keywords : MRI; phase contrast; black blood; STEAM; myocardial motion; MRI; magnetisk resonanstomografi; faskontrast; blodutsläckning; STEAM; myokardiell rörelse;

    Abstract : Doppler echocardiography is the conventional method for measurement of myocardial motion. However, the same clinical parameters can be measured with phase contrast magnetic resonance imaging (MRI). READ MORE

  4. 13. Characterization of Radiomics Features Extracted from Images Generated by the 0.35 T Scanner of an Integrated MRI-Linac

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Rebecka Ericsson Szecsenyi; [2020]
    Keywords : Medicine and Health Sciences;

    Abstract : Purpose: In an era of personalized oncology where the aim is to give every patient the right treatment at the right time an area of promising research is emerging called radiomics, or quantitative image analysis. The main underlying hypothesis is that pathophysiological information can be found in image texture not visible to the bare eye that can improve diagnosis, treatment adaption or be linked to a certain clinical outcome.

  5. 14. Implementation and verification of a quantitative MRI method for creating and evaluating synthetic MR images

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Aleksander Blagoiev; [2020]
    Keywords : MRI; Quantitative MRI; Synthetic MRI;

    Abstract : The purpose of this thesis was to implement and quantitatively test a quantitative MRI (qMRI) method, from which synthetic MR images are created and also evaluated. The parameter maps of T1, T2*, and effective proton density (PD*) were tested with reference tubes containing different relaxation times, and concentrations of water (H2O) and heavy water (D2O).

  6. 15. T2 Mapping Compared to Standard MRI Assessment : An Assessment of the Knee Cartilage on Distal Femur

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Jennie Andersson; [2019]
    Keywords : MRI; T2-mapping; articular cartilage; distal femur; knee; MR; T2-mapping; ledbrosk; distala lårbenet; knä;

    Abstract : Magnetic resonance imaging (MRI) has become the most important modality for assessment of pathological changes in the knee cartilage. The assessment of the cartilage is usually made by a set of anatomical MRI images with different sequences. READ MORE
