  1. 1. Studie av celltillväxt hos kondrocyter och mesenkymala stromaceller från benmärg- en utvärdering av optimala odlingsförhållanden

    Kandidat-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Sara Emilsson; [2023]
    Nyckelord :Articular cartilage; chondrocytes; mesenchymal stromal cells; viability; cell growth; Hyalint brosk; kondrocyter; mesenkymala stromaceller; viabilitet; celltillväxt;

    Sammanfattning : Introduktion: Hyalint brosk består av kondrocyter inbäddade i ett extracellulärt matrix som täcker alla kroppens synoviala leder. I dag är skador på hyalint brosk ett folkhälsoproblem med begränsade behandlingsmöjligheter. LÄS MER

  3. 2. Imaging of the MTP joint: Developing an imaging protocol optimised for damage detection and 3D modelling

    Master-uppsats, KTH/Fysik

    Författare :Johanna Jacobsson; [2022]
    Nyckelord :computed tomography; magnetic resonance imaging; cone beam computedtomography; cartilage; osteochondral lesions; metatarsal phalangeal joint; datortomografi; magnetisk resonanstomografi; kon-datortomografi; brosk; kondrala skador; metatarsalphalangen-leden;

    Sammanfattning : Walking without pain in the toe has a significant impact on a person’s well-being. Human mobility will be impaired in osteoarthritis of the big toe, and pain will occur during walking. By replacing the cartilage or bone injury with an individualised implant, osteochondral injuries to the knee and ankle can be treated. LÄS MER

  4. 3. Quantification of Fatty Acid Composition in Short T2* Tissue Using MRI – Comparison of 3 T and 7 T

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Felix Månsson; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Purpose: To optimize a method and develop an algorithm to quantify Fatty Acid Composition (FAC) in bone marrow adipose tissue. By using different reconstruction models, compare different MRI systems (3 T and 7 T) to find the optimal field strength and reconstruction model for FAC quantification. LÄS MER

  5. 4. Assessment of hip deformities during childhood: a combined approach of Machine Learning and Finite Element Analysis

    Master-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Klara Eriksson; Jonna Fahrman; [2022]
    Nyckelord :Biomechanics; Hip joint; Cartilage; Osteoarthritis; Machine learning; Finite element analysis; Technology and Engineering;

    Sammanfattning : Osteoarthritis is a degenerative disease that will cause pain and stiffness in the joint if not treated. One cause of early osteoarthritis in the hip joint is pediatric hip deformities. Hip deformities can occur in different stages of childhood and cause the bones to be misshapen or the hip joint to be dislocated. LÄS MER

  7. 5. Pre-planning of Individualized Ankle Implants Based on Computed Tomography - Automated Segmentation and Optimization of Acquisition Parameters

    Master-uppsats, KTH/Fysik

    Författare :Matilda Engström Messén; Elvira Moser; [2021]
    Nyckelord :osteochondral lesions of the talus; computed tomography; U-net; convolutional neural network; dice coefficient; fotled; ledbrosk; osteochondral lesion of the talus; datortomografi; U-net; convolutional neuralt nätverk; dicekoefficient;

    Sammanfattning : The structure of the ankle joint complex creates an ideal balance between mobility and stability, which enables gait. If a lesion emerges in the ankle joint complex, the anatomical structure is altered, which may disturb mobility and stability and cause intense pain. LÄS MER
