Dedicated to liver tissue analysis

The Dynamic Vascular Pattern (DVP) processing uses healthy tissue as reference and displays the hyper-enhanced and hypo-enhanced pixels over time by using warm and cold colour hues.

In addition to DVP, the Dynamic Vascular Pattern Parametric (DVPP) summarizes the specificities of the difference signals signatures into a single, easy-to-read color-coded image.

The final results are presented as parametric maps summarizing the dynamic vascular signature in a ROI in comparison with neighbouring parenchyma.

Dynamic Vascular Pattern Parametric (DVPP)

DVP signals, a classification is performed at the pixel level where each pixel is categorized into four classes according to the polarity of its difference signal over time.

A DVP image is then built as a color-coded map.

Practical Case:

Is the lesion hypo- or hyper-enhanced vs. reference tissue in late phase?
Lesion hypo-enhancement is easy to visualize on the DVP graph and DVPP image shows bipolar positive pattern.
