The quantitative accuracy of contrast agent concentration measurements for use in
Dynamic Contrast Enhanced MRI is investigated in phantom experiments. Two
commonly accepted techniques are compared. Both techniques require the direct
input of T1 measurements. Three candidates for clinical T1 mapping with different
overall accuracies were used to yield a total of six possible concentration evaluation
methods. Measurements of concentration using these methods were repeated several
times such that the overall accuracy and reproducibility may be evaluated.
