Abstract
Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is a noninvasive clinical technique devoted to the study of lesions in organs (ie, tumor), through the analysis of perfusion's dynamic of a suitable contrast agent (CA) in the tissues. The structures to be analyzed are natural in biomedical applications, nonrigid, and typically dynamic because they can change position, shape, and brightness. This often yields erroneous ...
