Evaluation of dynamic liver MR examination with Tissue 4D

Tissue 4D is an advanced postprocessing platform for pharmacokinetic modelling of dynamic-contrast enhanced (DCE), perfusion-weighted MRI datasets.
It facilitates the intuitive visualization of regions of strong wash-in and wash-out in color-coded maps and allows the extraction of perfusion parameters from DCE MRI.
This might help in the detection of tumor tissues in organs such as the liver.

Características e Benefícios

Visualization features

4D visualization (3D and over time). Color display of parametric maps describing the contrast media kinetics such as:

Transfer constant, measure of capillary permeability (Ktrans)
Reflux constant (Kep)
Extra vascular extra cellular volume fraction (Ve)
Initial Area-Under-Curve (iAUC) for the first 60 seconds Additional visualization of 2D or 3D morphological dataset

Post-processing features

Elastic 3D motion correction
Fully automatic calculation of subtracted images

Pharmacokinetic model

Pharmacokinetic calculation on a pixel-by-pixel basis using a one-compartment model. Calculation is based on the Tofts model. Various model functions are available. Manual segmentation and calculation on the resulting images.

The following resulting images can be saved as DICOM images:

3D motion-corrected, dynamic images
Colored images
Storage of calculated results
Export of results in the relevant layout format
