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

   Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik; Umeå universitet/Diagnostisk radiologi

   Författare :Amanda Eriksson; [2021]

   Sammanfattning : 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. LÄS MER

3. 2. Evaluation of Methods for Obtaining an Image Derived Input Function from Dynamic PET-images

   Master-uppsats, Umeå universitet/Institutionen för fysik; Umeå universitet/Radiofysik

   Författare :Sofia Jonsson; [2016]
   Nyckelord :;

   Sammanfattning : Dynamic PET is a technique to follow the uptake kinetics of radioactive labelled molecules in the human body. The kinetic behaviour may be analysed to acquire parameters, such as perfusion of blood to tissue, with the knowledge of the blood activity time curve (also called input function). LÄS MER
