1. 1. Sex Differences in Dopamine D1-type Receptors and Episodic Memory : an Imaging Study Across the Adult Lifespan

   University essay from Umeå universitet/Umeå centrum för funktionell hjärnavbildning (UFBI); Umeå universitet/Institutionen för psykologi

   Author : Anton Degerfält; [2023]
   Keywords : dopamine; D1DR; sex; episodic memory; ageing; PET; MRI;

   Abstract : Identification of the pathways that could be targeted to alleviate ageing-related cognitive decline is of prime importance. One of the most promising target mechanisms is connected to healthy dopaminergic ageing. READ MORE

3. 2. Psilocybin Induced Psychedelic Experiences : their Neural Mechanisms and Efficacy for Treating Depressive Disorders

   University essay from Högskolan i Skövde/Institutionen för biovetenskap

   Author : Linda Lindecrantz; Nicklas Villman; [2023]
   Keywords : psilocybin; depression; fMRI; systematic review; DMN;

   Abstract : The aim of this systematic review is to present the current literature on the therapeutic potential of the classic psychedelic compound psilocybin for depressive disorders and the neurocognitive mechanisms involved recorded with functional magnetic resonance imaging (fMRI). A comprehensive literature search was conducted in the electronic databases Web of Science, Scopus and Medline EBSCO using a Boolean search string containing the keywords psilocybin, depression, fMRI, MRI and PET.

4. 3. Effects of reconstruction parameters on the image quality and quantification of PET images from PET/MRI and PET/CT systems

   University essay from

   Author : Ali Amena Hussain; [2022-03-09]
   Keywords : Medical physics; PET CT; PET MRI; OSEM; BPL; NEMA IQ; positron emission tomography; magnetic resonance imaging; computed tomography; ordered Subset Expectation Maximization; The Bayesian Penalized Likelihood;

   Abstract : 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.

6. 5. 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
