1. Quantitative SPECT : studies of some factors influencing quantitation accuracy in single photon emission computed tomography
Sammanfattning : .... LÄS MER
2. Nuclear medicine methods in idiopathic Parkinsonism : pre- and postsynaptic dopamine SPECT
Sammanfattning : 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.

3. Advances in quantitative emission tomography : development and analysis of methods for validation and correction
Sammanfattning : 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. LÄS MER
4. Corrections for improved quantitative accuracy in SPECT and planar scintigraphic imaging
Sammanfattning : 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. LÄS MER
5. Quantitative imaging with PET : performance and applications of 76Br, 52Fe, 110mIn and 134La
Sammanfattning : 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. LÄS MER
