1. Validation and Robustness Analysis of Dynamic Contrast Enhanced MRI
University essay from Umeå universitet/Institutionen för fysikAbstract : In Dynamic Contrast Enhanced MRI there are several steps from the initial signal to obtaining the pharmacokinetic parameters for tumor characterization. The aim of this work was to validate the steps in the flow of data focusing on T1-mapping, Contrast Agent (CA)-quantification and the pharmacokinetical (PK) model, using a digital phantom of a head.

2. Improving the Modeling Framework for DCE-MRI Data in Hepatic Function Evaluation
University essay from Institutionen för medicin och hälsa; HälsouniversitetetAbstract : Background Mathematical modeling combined with prior knowledge of the pharmacokinetics of the liver specific contrast agent Gd-EOB-DTPA has the potential to extract more information from Dynamic Contrast Enhanced Magnetic Resonance Imaging (DCE-MRI) data than previously possible. The ultimate goal of that work is to create a liver model that can describe DCE-MRI data well enough to be used as a diagnostic tool in liver function evaluation. READ MORE

3. Human Whole Body Pharmacokinetic Minimal Model for the Liver Specific Contrast Agent Gd-EOB-DTPA
University essay from Medicinsk radiofysik; HälsouniversitetetAbstract : Magnetic resonance imaging (MRI) of the liver is an important non-invasive tool for diagnosing liver disease. A key application is dynamic contrast enhanced magnetic resonance imaging (DCE-MRI). With the use of the hepatocyte specific contrast agent (CA) Gd-EOB-DTPA it is now possible to evaluate the liver function. READ MORE

4. Feasibility Study of Phase Measurements of the Arterial Input Function in Dynamic Contrast Enhanced MRI
University essay from RadiofysikAbstract : Acquired data from dynamic contrast enhanced MRI measurements can be used to non-invasively assess tumour vascular characteristics through pharmacokinetic modelling. The modelling requires an arterial input function which is the concentration of contrast agent in the blood reaching the volume of interest as a function of time. READ MORE
