  4. 3. Improving the Modeling Framework for DCE-MRI Data in Hepatic Function Evaluation

    University essay from Institutionen för medicin och hälsa; Hälsouniversitetet

    Author : Anneli Mossberg; [2013]
    Keywords : DCE-MRI; modeling; irregular sampling; spatio-temporal standard deviation estimation; sampling time optimization; regional optimization; liver function evaluation; systems biology;

    Abstract : 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
