  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

    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

  3. 2. 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

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

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Anina Seidemo; [2018]
    Keywords : Medicine and Health Sciences;

    Abstract : 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). READ MORE

  5. 4. Quantification of the Cerebral Perfusion with the Arterial Spin Labelling 3D-MRI method. Quantification of the Cerebral Perfusion with the Arterial Spin Labelling 3D-MRI method

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Guillaume Gibert; [2014]
    Keywords : MRI; Magnetic Resonance Imaging; Cerebral Perfusion; ASL; Cerebral Blood Flow; Brain; Bolus Arrival Time;

    Abstract : The Arterial Spin Labelling (ASL) method is a Magnetic Resonance technique used toquantify the cerebral perfusion. It has the big advantage to be non-invasive so doesn’tneed the injection of any contrast agent. READ MORE

  6. 5. Perfusion MRI: Non-Linear Stochastic Regularization for Deconvolution of Model-Free Arterial Spin Labelling Data

    University essay from Lunds universitet/Sjukhusfysikerutbildningen

    Author : Andre Ahlgren; [2011]
    Keywords : MRI; Medicine and Health Sciences;

    Abstract : Introduction: Arterial spin labelling (ASL) is a non-invasive magnetic resonance imaging (MRI) technique for assessment of perfusion. ASL uses magnetically labelled blood water as a diffusible endogenous tracer to measure the perfusion of brain tissue, i.e. the cerebral blood flow (CBF). READ MORE
