1. 21. Dynamic glucose enhanced chemical exchange saturation transfer MRI : Optimization of methodology and characterization of cerebral transport kinetics

   Författare :Anina Seidemo; Lund Medicinsk strålningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemical exchange saturation transfer CEST ; Dynamic glucose enhanced DGE MRI; GlucoCEST; MRI; D-glucose; Fysicumarkivet A:2023:Seidemo;

   Sammanfattning : Dynamic glucose enhanced (DGE) chemical exchange saturation transfer (CEST) MRI is an emerging imaging technique that provides a molecular-specific type of image contrast, based on magnetic labelling of exchangeable protons. The technique enables the use of biodegradable sugars as contrast agents, and such compounds are believed to have less side effects than conventional MRI contrast agents. LÄS MER

3. 22. On potentials and limitations of perfusion MRI in neurological disorders

   Författare :Markus Fahlström; Mark Lubberink; Adam Espe Hansen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurological disease; MRI; Perfusion; 15O-water PET; Medicinsk radiofysik; Medical Radiophysics;

   Sammanfattning : Cerebral perfusion outlines several parameters which describe the status of cerebral haemodynamics. Numerous neurological diseases affect cerebral perfusion, thus the importance of diagnostic measurements. LÄS MER

4. 23. The extent of gynaecological cancer : Evaluation, outcome and quality of life

   Författare :Björg Jónsdottir; Karin Stålberg; Inger Sundström Poromaa; Håkan Ahlström; Päivi Kannisto; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ovarian cancer; endometrial cancer; cytoreductive surgery CRS ; PET MRI; MRI; Peritoneal cancer index PCI ; myometrial invasion MI ; quality of life.; Medicinsk vetenskap; Medical Science;

   Sammanfattning : The overall aim of this thesis was to enhance treatment planning for gynaecological cancer patients and identify women that are more likely to have impaired quality of life (QoL) after treatment. In a retrospective cohort study on ovarian cancer, the peritoneal cancer index (PCI) was examined in relation to incomplete cytoreductive surgeries (CRS) and surgical complications (n=167).

5. 24. PET and MR imaging in prostate cancer

   Författare :Kristina Sandgren; Tufve Nyholm; Joakim Jonsson; Camilla Thellenberg-Karlsson; Lennart Blomqvist; Heidi Lyng; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; PSMA; MRI; PET MRI; imaging; prostate cancer; intraprostatic tumour detection; radiofysik; radiation physics;

   Sammanfattning : The current risk assessment of prostate cancer (PC) relies on histopathological samples from biopsies and clinical variables such as prostate-specific antigen (PSA). However, this comes with uncertainties and in some cases it can be challenging to separate patients who would benefit from radical treatment and those who would not. LÄS MER

7. 25. Image-based multi-omics data integration : Exploring whole-body PET/MRI, -omics data and body composition

   Författare :Robin Visvanathar; Håkan Ahlström; Joel Kullberg; Jan Eriksson; Katrine Riklund; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Body composition; Imiomics; genomics; metabolomics; MRI; PET; insulin sensitivity; T2D;

   Sammanfattning : Advanced body composition analysis with whole-body imaging could uncover novel associations between regional tissue composition and metabolic disease. Imiomics is an automated image analysis framework that enables large-scale integration of magnetic resonance imaging (MRI) data and orthogonal technologies such as metabolomics and genomics for the detailed study of body composition.
