1. 1. Total body perfusion imaging with 15O-water PET

   University essay from Umeå universitet/Institutionen för fysik

   Author : Anna Åhlström; [2023]
   Keywords : ;

   Abstract : 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

3. 2. Visual Transformers for 3D Medical Images Classification: Use-Case Neurodegenerative Disorders

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Pooriya Khorramyar; [2022]
   Keywords : Artificial intelligence; Explainable AI; Machine learning; Deep learning; Computer vision; Vision Transformer; Visual Transformer; ViT; Convolutional Neural Network; CNN; Neurodegenerative disorder; Mild cognitive impairment; Alzheimer s disease; Fluorodeoxyglucose; 18F-FDG; Positron Emission Tomography; PET; Brain; Brain scan;

   Abstract : A Neurodegenerative Disease (ND) is progressive damage to brain neurons, which the human body cannot repair or replace. The well-known examples of such conditions are Dementia and Alzheimer’s Disease (AD), which affect millions of lives each year. READ MORE

4. 3. Quantification of cerebral blood flow with 15O-water PET : A comparison study between PET/CT and PET/MR and two different blood sampling instruments

   University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Diagnostisk radiologi

   Author : Amanda Eriksson; [2021]
   Keywords : Cerebral Blood Flow; CBF; oxygen-15-labelled water; PET CT; PET MR; Quantification of CBF; Image Derived Input Function; IDIF; Blood Sampled Input Function; BSIF; Arterial Input Function; AIF; Tracer Kinetic Modelling; Single Tissue Compartmental Model; 1TCM;

   Abstract : Cerebral blood flow quantification is a vital diagnostic tool for disease monitoring and used for diagnosing a variation of pathological conditions. The human brain requires roughly about 20 % of the total cardiac output to sustain normal functioning, hence the perfusion of blood is an important factor to deliver oxygenated blood. READ MORE

5. 4. FDG PET and MRI as biomarkers of Tau pathology in Alzheimer’s disease

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Putu Ayuwidia Ekaputri; [2021]
   Keywords : Alzheimer’s disease; fdg pet; mri; tau pet; tau pathology;

   Abstract : Fluorodeoxyglucose Positron Emission Tomography (FDG PET) and Magnetic Resonance Imaging (MRI) are commonly used in a clinical setting as an examination in Alzheimer’s Disease (AD) patients. FDG PET is an imaging tool to evaluate hypometabolism; meanwhile, the MRI observes the brain volume. READ MORE

6. 5. Prioritization of Informative Regions in PET Scans for Classification of Alzheimer's Disease

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Fredrik Mårtensson; Erik Westberg; [2021]
   Keywords : ;

   Abstract : Alzheimer’s Disease (AD) is a widespread neurodegenerative disease. The disease causes brain atrophy, resulting in memory loss, decreased cognitive ability, and eventually death. There is currently no cure for the disease, but treatment may delay the onset. Therefore, it is crucial to detect the disease at an early stage. READ MORE
