  4. 2. Nuclear medicine methods in idiopathic Parkinsonism : pre- and postsynaptic dopamine SPECT

    Author : Susanna Jakobson Mo; Katrine Åhlström Riklund; Anne Larsson Strömvall; Lars Forsgren; Rimma Axelsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear medicine; SPECT; 123I-FP-Cit; 123I-IBZM; dopamine; parkinsonism; Parkinson’s disease; multiple system atrophy; progressive supranuclear palsy; Radiology; radiologi;

    Abstract : Background: Single photon emission computed tomography (SPECT) with dopamine transporter (DAT) and dopamine D2 receptor (D2R) ligands can visualise the integrity of the nigrostriatal dopamine system. Parkinson’s disease (PD) and the atypical parkinsonian diseases (APD), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA), have similar symptoms and dopamine depletion, but differ in pharmacological response and prognosis.

  5. 3. Advances in quantitative emission tomography : development and analysis of methods for validation and correction

    Author : Cathrine Jonsson; Magnus Dahlbom; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SPECT; Quantification; rCBF; Scatter correction; Phantoms; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : The nuclear medicine imaging techniques SPECT and PET are sensitive tools in mapping various physiological and biochemical processes in vivo. This work was devoted to investigations of methodological and physical properties of the SPECT technique as well as developing methods for validation and correction. READ MORE

  6. 4. Corrections for improved quantitative accuracy in SPECT and planar scintigraphic imaging

    Author : Anne Larsson; Lennart Johansson; Katrine Åhlström Riklund; Bertil Axelsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Quantitative SPECT; scintigraphic imaging; attenuation correction; scatter correction; collimator-detector response; septal penetration; background correction; Monte Carlo simulation; Radiological physics; Radiofysik;

    Abstract : A quantitative evaluation of single photon emission computed tomography (SPECT) and planar scintigraphic imaging may be valuable for both diagnostic and therapeutic purposes. For an accurate quantification it is usually necessary to correct for attenuation and scatter and in some cases also for septal penetration. READ MORE

  7. 5. Quantitative imaging with PET : performance and applications of 76Br, 52Fe, 110mIn and 134La

    Author : Mark Lubberink; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; PET; Positron Emission Tomography; Quantitative Imaging; bromine; iron; indium; lanthanum; Onkologi; Oncology; Onkologi; Oncology; Onkologi;

    Abstract : The use of positron emission tomography (PET) has so far mainly been limited to a few nuclides with short half-lives such as 11C and 18F. Certain applications require nuclides with longer half-lives, such as 76Br and 52Fe. READ MORE
