11. Differences in tumor volume for treated glioblastoma patients examined with 18F-fluorothymidine PET and contrast-enhanced MRI
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : Background: Glioblastoma (GBM) is the most common and malignant primary brain tumor. It is a rapidly progressing tumor that infiltrates the adjacent healthy brain tissue and is difficult to treat. Despite modern treatment including surgical resection followed by radiochemotherapy and adjuvant chemotherapy, the outcome remains poor. LÄS MER
12. Eventuella fosterskador till följd av magnetkameraundersökning på gravida kvinnor : En litteraturstudie med systematisk sökning
Kandidat-uppsats, Örebro universitet/Institutionen för hälsovetenskaperSammanfattning : Background: During the recent years, magnetic resonance imaging (MRI) has evolved to become one of the most commend used diagnostic methods. Although MRI is considered safe and a good diagnostic method of foetuses and pregnant women, the research data is too small to claim that it is completely risk-free. LÄS MER
13. Setup Implementation for a Direct Measurement Technique of the Magnetocaloric Effect
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : This project presents an attempt to construct a setup and implement a reliable technique for measuring the magnetocaloric effect (MCE) on various materials via a direct method for the acquisition of the data. The main objective of the latter is to produce a ∆Tadiabatic vs T graph over a reasonable temperature span (-100◦C up to 220◦C) by thermal monitoring of a magnetic material exposed to an oscillating magnetic field with a maximum strength of 1.

14. Förekomst av Gadoliniumretention i hjärna samt dess negativa biverkningar. Litteraturstudie
Kandidat-uppsats, Lunds universitet/Institutionen för hälsovetenskaperSammanfattning : En magnetisk resonanstomografiundersökning utgör en viktig del för diagnosticering. För att kunna säkerställa diagnosen, vid dessa undersökningar, används ofta Gadoliniumbaserat kontrastmedel. Syftet med föreliggande vetenskapliga litteraturöversikt var att kartlägga Gadoliniumretention i hjärnan och dess negativa biverkningar. LÄS MER
15. Software Development and Qualification Testing of a CubeSat X-ray Monitor
Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknikSammanfattning : The CUBES (CUbesat x-ray Background Explorer using Scintillators) is a payload on the KTH student satellite MIST (MIniature STudent satellite) to evaluate Silicon Photo-multiplier technology and new scintillators such as GAGG (Gadolinium Aluminium Gallium Garnet, Gd3Al2Ga3O12) for future use in hard X-ray polarisation studies of Gamma-Ray Bursts. CUBES itself is designed to study the MIST in-orbit radiation environment by using a detector which is comprised of a silicon photomultiplier coupled to different scintillator materials. LÄS MER
