1. Total body perfusion imaging with 15O-water PET
University essay from Umeå universitet/Institutionen för fysikAbstract : Background Positron emission tomography scanners can be used together with the PET tracer 15O-water to image perfusion in the body. It has mainly been used to image perfusion in the brain and heart. The new total-body PET scanners have a larger axial field-of-view, making imaging of the whole body possible without moving the patient. READ MORE

2. Visualizing osteonecrosis of jaws through neutrophil elastase : [11C]NES novel PET tracer
University essay from Uppsala universitet/Institutionen för läkemedelskemiAbstract : 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.

3. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems
University essay fromAbstract : 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.

4. Lesion Segmentation in 3D FDG-PET/CT Scans Using Deep Learning
University essay from Uppsala universitet/Institutionen för informationsteknologiAbstract : Drug development is an expensive, long and complex process for pharmaceutical companies all around the world. One way to make it more reliable is to evaluate the drug at its early stages, so the decision can be made to go forward or move to another drug, which is also a time-consuming and costly task to be done by human experts.

5. Hypoxic Target Volume Determination in PET/CT Imaging : The Impact of Deformable Image Registration
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : Using a tailored dose distribution for personalized radiotherapy with the help of positron emission tomography (PET) might give an edge for successful tumour elimination. One of the main determinants for tumour radioresistance in several solid tumours has been investigated as hypoxia, including head and neck cancer (HNC). READ MORE
