MRDAC - MR development and application center

DCE-MRI (Dynamic contrast-enhanced magnetic resonance imaging) is the key method to evaluate anti-angiogenic and anti-vascular agents in clinical trials.

  • It allows to determine the functional response of tumor to the anti cancer agents on a microvascular level where parameters like vascular permeability are important biomarkers.
  • It is a non-invasive technique with low restrictions to patient comfort and is the method of choice to follow-up drug action in tumor and surrogate tissues.
  • It directly reflects the impact of the therapeutic drug on tumor state by angiogenesis assessment.

DCE-MRI data analysis is performed by an in-house software analysis tool

  • written in Matlab according to GCP-requirements,
  • to determine pharmacological parameter (Ktrans, kep) by pharmacokinetic modelling which are related to physiological parameters like vessel permeability and extra-vascular volume.
  • with pharmacodynamic models to analyze clinical and pre clinical MRI data,
  • with region of interest (ROI) and pixel wise analysis,
  • with handling of 2D, 3D and multi echo data sets,
  • with an user-friendly graphical user interface and
  • with a flexible design to meet the demands in the progress of modeling and new study trials.

  • (please click for magnified image) Screenshot example of the analysis tool.

MRDAC provides a complete package for the implementation of clinical phase trials including standard and advanced DCE-MRI measurement protocols and DCE-MRI analysis tools using professional software.
MRDAC has more than 10 years experience performing DCE-MRI examinations and analysis in the context of clinical trials.

There are allways ongoing clincial trials in collaboration with the Center of Tumorbiology. For more information be referred to the pages of our clinical partner: Center of Tumorbiology.
