  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]
    Nyckelord :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;

    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. Natural sugar as an MRI contrast agent for brain cancer detection using chemical exchange saturation transfer (CEST) imaging at 3T

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Anina Seidemo; [2018]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Hjärntumörer utgör cirka 2,5% av alla cancerdiagnoser i Sverige (2013) och femårsöverlevnaden är cirka 50%. Hjärntumörer diagnostiseras med bildtagningstekniker såsom datortomografi (CT), positronemissionstomografi (PET) och magnetkamera (MR). LÄS MER

  4. 3. 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
