1. Visualizing osteonecrosis of jaws through neutrophil elastase : [11C]NES novel PET tracer
Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Institutionen för läkemedelskemiSammanfattning : Radiation and medical drugs are used to fight head and neck cancer, but unfortunately in some cases these treatments cause development of other diseases and injuries. Osteoradionecrosis (ORN) and medical-related osteonecrosis of the jaw (MRONJ) are dreaded late complications in jaws from radiation therapy and medical drugs and cause great suffering to those affected.

2. Large-scale transfer of lesion segmentations from PET to CT
Master-uppsats, Uppsala universitet/Institutionen för informationsteknologiSammanfattning : The introduction of AI technology has sparked a revolutionary lesion segmentation solution to address challenges in the medical field. After extensive research, the competencies of this technology have been verified. LÄS MER
3. Respiratory Motion Correction in PET Imaging: Comparative Analysis of External Device and Data-driven Gating Approaches
Master-uppsats, KTH/FysikSammanfattning : Positron Emission Tomography (PET) is pivotal in medical imaging but is prone to artifactsfrom physiological movements, notably respiration. These motion artifacts both degradeimage quality and compromise precise attenuation correction. LÄS MER
4. Jämförelse av aktivitet i urinblåsan hos 18F-PSMA-PET patienter med och utan hydrering
Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)Sammanfattning : Background: Prostate cancer is the most prevalent form of cancer affecting men.In case of biochemical recurrence, positron emission tomography (PET) targeting prostate-specific membrane antigen (PSMA) on prostate tumor cells is primarily used, in combination with computed tomography (CT), for detection and localization of recurrence.

5. TransRUnet: 2D Detection and Segmentation of Lymphoma Lesions in Full-Body PET-CT Images
Master-uppsats, KTH/Medicinteknik och hälsosystemSammanfattning : Identification and localization of FDG-avid lymphoma lesions in PET-CT image volumes is of high importance for the diagnosis and monitoring of treatment progress in lymphoma patients. This process is tedious, time-consuming, and error-prone, due to large image volumes and the heterogeneity of lesions. LÄS MER
