  1. 1. Brain processing of experimental muscle pain and its interrelation with proprioception and muscle fatigue positron emission tomography study

    Detta är en avhandling från Umeå : Umeå University

    Författare :A Korotkov; Högskolan i Gävle.; Umeå universitet.; [2005]
    Nyckelord :Experimental muscle pain; Hypertonic saline; Kinesthesia; Proprioception; Movernent; Vibration; Muscle fatigue; Brain; Imaging; Positron emission tornography; Regional cerebral blood - flow; Movement; Positron emission tomography; Regional cerebral blood flow;

    Sammanfattning : Chronic muscle pain is a significant medical and social problem and better understanding of the pathophysiological mechanisms involved is an important requirernent for further development of diagnostics, treatment and rehabilitation methods. Experimental imaging studies have investigated functional neuroanatomy of different pain cornponents. LÄS MER

  7. 5. A clinical positron emission tomography facility. 2-[18-F]FDG studies: development and results

    Detta är en avhandling från Radiation Physics, Lund

    Författare :Tomas G Ohlsson; [1996]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; head and neck cancer; monitoring therapy effect; quantification; normalization; 511 keV SPECT; rotating PET scanner; 2-[18-F]FDG; isotope production; 18-F; PET; positron emission tomography; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : Positron emission tomography (PET) is a tracer technique used for quantitative in vivo studies of physiological and biochemical processes. Because of the use of positron-emitting radionuclides such as 11-C, 13-N, 15-O and 18-F, which are isotopes of the biologically ubiquitous elements, it is possible to label radiopharmaceuticals which trace biochemical processes precisely.
