  2. 1. Quantification Methods for Clinical Studies in Nuclear Medicine - Applications in AMS, PET/CT and SPECT/CT

    Author : Marie Sydoff; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear Medicine; AMS; PET CT; SPECT CT; dosimetry; internal dosimetry; quantification; activity quantification; volume delineation; radiation; biokinetics; pharmacokinetics; biodistribution;

    Abstract : An essential part of the development of new radiopharmaceuticals for use in diagnostic nuclear medicine is the determination of its biokinetic properties. The uptake and turn-over of the radiopharmaceutical in the source organs is of great interest since this could determine whether the radiopharmaceutical would be suitable for clinical use or not.

  4. 2. Physical activity and energy expenditure in clinical settings using multisensor activity monitors

    Author : Daniel Arvidsson; Göteborgs universitet; []
    Keywords : Physical activity; energy expenditure; children; activity monitors; multisensors; validity; reliability; congenital heart defects; aerobic fitness;

    Abstract : Background: Objective methods need to replace subjective methods for accurate quantification of physical activity. To be used in clinical settings objective methods have to show high reliability, validity and feasibility. The commonly used activity monitors are unable to detect the variety of physical activities.

  5. 3. Activity quantification based on scintillation camera imaging - Application to 111In/90Y radioimmunotherapy

    Author : David Minarik; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radioimmunotherapy; bremsstrahlung imaging; activity quantification; SPECT; conjugate view; Yttrium;

    Abstract : Radionuclide therapy (RNT), is important for the treatment of certain benign and malignant diseases. 90Y-Zevalin™ therapy has become an established method of treating patients with non-Hodgkin B-cell lymphoma. READ MORE

  6. 4. Ultrasonic Quantification of Skeletal Muscle Dynamics : Feasibility and Limitations

    Author : Frida Lindberg; Lars-Åke Brodin; Christer Grönlund; Tomas Jansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrasound; skeletal muscle; intramuscular; dynamics; Tissue Doppler Imaging; Speckle Tracking; strain; quantification;

    Abstract : Pain and disorders of the human skeletal muscles are one of the most common reasons for medical consultations in the western countries today and there is a great need to improve both the understanding and treatment of several different muscular conditions.Techniques describing the muscle function in vivo are often limited by either their invasiveness or lack of spatial resolution.

  7. 5. Image Processing for Quantitative Scintillation-Camera Imaging. Application to Radionuclide Therapy

    Author : Katarina Sjögreen Gleisner; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; 131-I; Clinical physics; SPECT; conjugate-view; volume quantification; activity quantification; image registration; image segmentation; medicinsk instrumentering; Nuclear medicine; radiobiology; Nukleärmedicin; radiobiologi; Radiopharmaceutical technology; Radiofarmaceutisk teknik;

    Abstract : Individual-based determinations of the absorbed dose in radionuclide therapy largely rely on absolute measurement of the activity distribution and its redistribution over time. Scintillation-camera imaging is the most commonly employed measuring technique, applied in planar or SPECT mode, sometimes in combination with structural images from CT. READ MORE
