Dynamic Contrast Enhancement: Analysis's Models and Methodologies
Abstract
The aim of this chapter is to provide an overview about models and methodologies used for the Dynamic Contrast Enhancement (DCE) analysis. DCE is a non-invasive methodology aimed to diagnostic the nature of a lesion on the base of the perfusion’s dynamic of specific contrast agents. The idea at the base of DCE is that, in several pathological tissues, including tumors and inflammatory diseases, the angiogenic process is abnormal, hence the characterization of vascularisation structure may be used to support the diagnosis. In this chapter, we will describe the basic DCE procedures and introduce some of its most innovative evolution based on the pharmacokinetic analysis technique (PK), and the empirical model (EM). Even if DCE is still a medical research topic, there is large interest for this type of approach in biomedical applications as witnessed by the availability of specific tools in the last generation top-class US, CT and MR machines.
