Etat de l'art en ultrasonographie doppler du foie

Despite the advancements of CT and MRI imaging, ultrasonography (US) has continued to improve and to develop as well as to have enormous applications, implications, and importance in diagnostic imaging of the liver. While gray-scale imaging has improved significantly, so that the definition of subtle lesions only a few millimeters in size is now possible, recent years have seen the most exciting advances in the Doppler US technology. The development of power Doppler imaging has substantially improved perception of tumor vascularity. The introduction of US contrast media in combination with harmonic imaging has even further enlarged the potential uses of this technique. This article explores the most recent advances in Doppler US of the liver, with emphasis on its potential clinical applications.
