    Sammanfattning : The biological mechanisms involved in bone regeneration in osteoporotic bone and the effect of antiresorptive drugs in relation to surgically inserted biomaterials are not fully understood. Improved osseointegration of titanium implants but also adverse effects of antiresorptive therapies, such as osteonecrotic jaw have been described in the literature. LÄS MER

  3. 7. The Human Cochlea and Cochlear Implantation : Morphological Characteristics and Clinical Correlations

    Författare :Nadine Schart-Morén; Helge Rask-Andersen; Elina Mäki-Torkko; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cochlear implantation; micro-CT; synchrotron; facial nerve stimulation; hearing preservation; round window;

    Sammanfattning : The most common sensory deficit in the world is sensorineural hearing loss. Cochlear implantation (CI) can majorly contribute to restore hearing, not only in patients with severe to profound hearing loss, but also in hearing-impaired patients with residual low-frequency hearing.

    Sammanfattning : Throughout the last century, medical imaging has come to revolutionise the way we diagnose disease, and is today an indispensable part of virtually any clinical practice. In cardiovascular care imaging is extensively utilised, and the development of novel techniques promises refined diagnostic abilities: ultrasound elastography allows for constitutive tissue assessment, 4D flow magnetic resonance imaging (MRI) enables full-field flow mapping, and micro-Computed Tomography (CT) permits high-resolution imaging at pre-clinical level.

  5. 9. Image Analysis for Trabecular Bone Properties on Cone-Beam CT Data

    Författare :Eva Klintström; Örjan Smedby; Rodrigo Moren; Torkel Brismar; Dan Mellström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Trabecular bone structure as well as bone mineral density (BMD) have impact on the biomechanical competence of bone. In osteoporosis-related fractures, there have been shown to exist disconnections in the trabecular network as well as low bone mineral density. Imaging of bone parameters is therefore of importance in detecting osteoporosis. LÄS MER

  7. 10. Image Analysis and Visualization of the Human Mastoid Air Cell System

    Författare :Olivier Cros; Michael Gaihede; Hans Knutsson; Magnus Borga; Torbjörn Ledin; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : From an engineering background, it is often believed that the human anatomy has already been fully described. Radiology has greatly contributed to understand the inside of the human body without surgical intervention. LÄS MER
