title: Contrast-enhanced and 3-dimensional endoscopic ultrasonography.
abstract: Recent progress of the data processing applied to ultrasonographic (US) examination has made it possible to develop new software. The US workstation of the last generation thus incorporated in their center a computer allowing a precise treatment of the US image. This advancement has made it possible to work out new images such as 3-dimensional (3D) US, contrast harmonic US associated with the intravenous injection of contrast agents, and even more recently, elastography. These techniques, quite elaborate in percutaneous US at present, are to be adapted and evaluated with endoscopic US (EUS). The contribution of contrast agents of US to pancreatic EUS and then 3D EUS are successively approached in this article.
