1. 1. 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.

3. 2. Development of a tool for analysis and visualization of longitudinal magnetic resonance flowmeasurements : of subarachnoid hemorrhage patients in the neurointensivecare unit

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : ILDI ADOK; [2023]
   Keywords : 2D phase contrast MRI; subarachnoid hemorrhage; cerebral blood flow; visualization; neurointensive care;

   Abstract : Patients who are treated in an intensive care unit need continuous monitoring in orderfor clinicians to be prepared to intervene should a secondary event occur. For patientstreated at the neurointensive care unit (NICU) who have suffered a subarachnoid hemorrhage (SAH) this secondary event could be ischemia, resulting in a lack of blood flow. READ MORE

4. 3. Sex-specific pathological response to Traumatic Brain Injury

   University essay from Lunds universitet/Examensarbeten i molekylärbiologi

   Author : Christopher Fry; [2022]
   Keywords : Biology and Life Sciences;

   Abstract : Traumatic brain injury (TBI) is one of leading causes of death in the world; survivors commonly exhibit behavioural changes and neurocognitive defects in the long-term. Following TBI, rapid changes in the neurovascular unit (NVU) occur as the permeability of the blood brain barrier (BBB) increases and cerebral blood flow (CBF) becomes dysregulated. READ MORE

5. 4. 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

6. 5. Deep Learning-Based Identification of Ischemic Regions in Native Head CT Scans

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Maximilian Hornung; [2020]
   Keywords : ;

   Abstract : Stroke is one of the major causes of death and disability worldwide. Fast diagnosis is of critical importance for stroke treatment. In clinical routine, a non-contrast CT (NCCT) is typically acquired immediately to determine whether the stroke is ischemic or hemorrhagic and plan therapy accordingly. READ MORE
