  1. 1. In Vivo Evaluation of Skeletal Muscle Morphological and Mechanical Properties using Medical Imaging

    Författare :Zhongzheng Wang; Ruoli Wang; Elena Gutierrez Farewik; Rodrigo Moreno; Jonas Stålhand; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle volume; fascicle length; pennation angle; anisotropy; three-dimensional freehand ultrasound; magnetic resonance imaging; diffusion tensor imaging; magnetic resonance elastography; Muskelvolym; fascikellängd; pennationsvinkel; anisotropi; tredimensionellt frihandsultraljud; magnetisk resonanstomografi; diffusionstensoravbildning; magnetisk resonanselastografi; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : Skeletal muscles are soft tissues that play an important role in maintaining body posture and enabling movements through force generation. The force-generating capacity is associated with the morphological and mechanical properties of the muscle. LÄS MER

  3. 2. Adverse Muscle Composition : Revisiting Sarcopenia in General Population and Liver Disease using Magnetic Resonance Imaging

    Författare :Jennifer Linge; Mattias Ekstedt; Patrik Nasr; Martin Henriksson; Tommy Cederholm; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Sarcopenia - from the Greek words 'sarx' (flesh) and 'penia' (loss) - was, when coined in 1989, a term denoting the decline in muscle mass and strength that occurs with aging. Such definition implies everyone suffers from sarcopenia to varying degrees, which naturally makes studying sarcopenia challenging. LÄS MER

  4. 3. Quantitative Muscle Composition Analysis Using Magnetic Resonance Imaging

    Författare :Anette Karlsson; Magnus Borga; Anneli Peolsson; Janne West; Todd Parrish; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Muscle Composition; Muscle fat Infiltration; Magnetic Resonance Imaging;

    Sammanfattning : Changes in muscle tissue composition, e.g. decrease in volume and/or increase of fat infiltration, are related to adverse health conditions such as sarcopenia, inflammation, muscular dystrophy, and chronic pain. LÄS MER

  5. 4. Methods for quantitative analysis of myocardial perfusion SPECT : validated with magnetic resonance imaging, phantom studies and expert readers

    Författare :Helen Fransson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Segmentation; Quantification; Spline; Image registration; Cardiac image analysis; Myocardial perfusion SPECT;

    Sammanfattning : In this thesis, methods for automated analysis of myocardial perfusion single photon emission computer tomography (myocardial perfusion SPECT, MPS) images have been successfully developed and evaluated. MPS images show the perfusion of the myocardium and are used for diagnosing patients with suspected ischemic heart disease. LÄS MER

  7. 5. Vibration-induced muscle injury in the hand - experimental and clinical studies

    Författare :Lars Necking; Malmö Handkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatologi; Surgery; muscle morphometry; intrinsic hand muscle; muscle strength; muscle injury; hand weakness; Vibration exposure; hand-arm vibration syndrome; orthopaedics; traumatology; Kirurgi; ortopedi;

    Sammanfattning : Exposure to vibration is known to cause vasospastic white fingers and/or sensorineural symtoms such as numbness and tingling in fingers and/or musculoskeletal disorders such as reduction in muscle force, fatigue and reduced endurance. Classifications for the vasospastic and sensorineural symptoms are established. LÄS MER
