    Sammanfattning : Cancer is one of the most common causes of death worldwide. When given optimal treatment, however, the risk of severe illness may greatly be reduced. Determining optimal treatment in turn requires evaluation of disease progression and response to potential, previous treatment. LÄS MER

  3. 2. Förbättring av kärnkraftssäkerhet genom erfarenhetsåterföring : En benchmarkingstudie för att identifiera bästa praxis

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen Vi3

    Sammanfattning : The existence and viability of nuclear power have been at the center of debate for several decades due to the inherent safety risks. Disasters such as Three Mile Island (1979), Chernobyl (1986), and Fukushima Daichii (2011) have resulted in severe consequences but have also led to higher safety standards and precautionary measures within the nuclear industry.

    Sammanfattning : Does the active membrane transporter, Na+,K+-ATPase dimerize? If it does, whatis the functional benefit? Does it increase or decrease the turnover rate? Theseare still unanswered questions and current research topics. Previous studies havedemonstrated dimerizations in closely related proteins of the P-type ATPase family. LÄS MER

  5. 4. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems

    Master-uppsats,

    Författare :Ali Amena Hussain; [2022-03-09]
    Nyckelord :Medical physics; PET CT; PET MRI; OSEM; BPL; NEMA IQ; positron emission tomography; magnetic resonance imaging; computed tomography; ordered Subset Expectation Maximization; The Bayesian Penalized Likelihood;

    Sammanfattning : Aim: To study how reconstruction parameters affect the positron emission tomography (PET) image quality and quantitative results for the different lesion to background radioactivity ratios in three different PET systems. Introduction: Multimodality imaging that combines magnetic resonance imaging (MRI) or computed tomography (CT) with a PET system can produce medical images containing both functional and anatomical information.

    Sammanfattning : Parkinson’s Disease (PD) is the fastest growing neurodegenerative disease, currently affecting two to three percent of the population over 65. Studying functional connectivity (FC) in PD patients may provide new insights into how the disease alters brain organization in different subjects. LÄS MER
