1. 6. 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

3. 7. Dynamic susceptibility contrast MRI calibrated using T1-based steadystate CBV and vascular space occupancy (VASO) Comparison with model-free arterial spin labelling

   University essay from Lunds universitet/Sjukhusfysikerutbildningen

   Author : Emelie Lindgren; [2009]
   Keywords : MRI; Medicine and Health Sciences;

   Abstract : IntroductionThe perfusion-related parameters cerebral blood flow (CBF) and cerebral blood volume (CBV) can be measured using dynamic susceptibility-contrast magnetic resonance imaging (DSC-MRI). However, absolute values of CBF and CBV are often overestimated and quantification of these parameters is challenging. READ MORE
