  1. 1. Optimizing the magnetic tracer technique for sentinel lymph node detection and tumour localization in breast cancer surgery

    Författare :Allan Jazrawi; Andreas Karakatsanis; Staffan Eriksson; Fredrik Wärnberg; Jonas Manjer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast Cancer; Sentinel Node; Super paramagnetic ironoxide nanoparticles; SPIO; Skin Staining; Magnetic resonance imaging; magnetic seed; guidewire; Kirurgi; Surgery;

    Sammanfattning : Breast cancer is the most common form of cancer in women, and the primary treatment modalities are still breast-conserving surgery (BCS) and sentinel lymph node dissection (SLND) in most cases. Superparamagnetic iron oxide nanoparticles (SPIO) are gaining momentum as a tracer for sentinel lymph node detection. LÄS MER

  3. 2. Fluorescence Guided Resection of Brain Tumors : Evaluation of a Hand-held Spectroscopic Probe

    Författare :Johan Richter; Karin Wårdell; Jan Hillman; Peter Siesjö; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Malignant gliomas grow infiltrative in the brain and can therefore not be completely removed by neurosurgical means. However, for an optimized oncological treatment it has proven useful to resect as much as possible of tumor. The identification of the tumor in the marginal zone is difficult but crucial. LÄS MER

  4. 3. Mechanical Circulatory Support in Left Ventricular Heart Failure

    Författare :Petter Schiller; Laila Hellgren; Anders Jönsson; Göran Dellgren; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mechanical Circulatory Support; Left Ventricular Heart Failure; Left Ventricular Assist Device; Extracorporeal Membrane Oxygenation; ECMO; Thorax Surgery; Thoraxkirurgi;

    Sammanfattning : Short-term mechanical circulatory support (MCS) with ventricular assist devices or veno-arterial extracorporeal membrane oxygenation (VA ECMO) has become the standard treatment in patients with cardiogenic shock unresponsive to pharmacological treatment. However, the haemodynamic effects of these devices are not yet fully described, nor are their effects on ventricular function and myocardial recovery. LÄS MER

  5. 4. Interactive 3D Image Analysis for Cranio-Maxillofacial Surgery Planning and Orthopedic Applications

    Författare :Johan Nysjö; Ingela Nyström; Filip Malmberg; Ida-Maria Sintorn; Jayaram K. Udupa; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; medical image analysis; interactive segmentation; volume rendering; computed tomography; Computerized Image Processing; Datoriserad bildbehandling;

    Sammanfattning : Modern medical imaging devices are able to generate highly detailed three-dimensional (3D) images of the skeleton. Computerized image processing and analysis methods, combined with real-time volume visualization techniques, can greatly facilitate the interpretation of such images and are increasingly used in surgical planning to aid reconstruction of the skeleton after trauma or disease.

  7. 5. The role of simulation technology for skills acquisition in image guided surgery

    Författare :Gunnar Ahlberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Endoscopy; Laparoscopy; Virtual reality; Simulation; Proficiency-based training; Image guided surgery; Surgical education; Objective assessment.;

    Sammanfattning : Technical proficiency is an essential ingredient in surgical competence, which has hitherto been poorly evaluated. The introduction of disruptive technology into the Operating Room (OR) with respect to operative procedures requires an equally disruptive paradigm shift in surgical training that matches the development in OR technology.
