Reference Region-Based Pharmacokinetic Modeling in Quantitative Dynamic Contract-Enhanced MRI Allows Robust Treatment Monitoring in a Rat Liver Tumor Model Despite Cardiovascular Changes
In this work, two pharmacokinetic modeling techniques, population arterial input function model, and reference region model, were applied to dynamic contract-enhanced MRI data, to test the influence of a change in heart rate on modeling parameters. A rat population arterial input function was generated by dynamic contrast-enhanced computed tomography measurements using the MR contrast agent gadoli
