[Bowel imaging--a reevaluation. Part 1: Conventional techniques and ultrasonography].
For decades fluoroscopy was the only adequate imaging modality in the diagnostic evaluation of the bowel. In the 1980 s new techniques such as MRI, CT and flexible fiber-optic endoscopy were introduced into the daily routine and revolutionized bowel imaging. Wireless capsule endoscopy (WCE) is the latest technical innovation for visualizing the bowel. Today a broad range of different imaging methods is available. This article provides a review of state-of-the-art bowel imaging and is divided into two parts. The first part addresses conventional X-ray techniques and ultrasonography and the second part discusses bowel imaging with computed tomography (CT) and magnetic resonance imaging (MRI). The goal of this article is to present the imaging techniques and to discuss them in the context of competitive methods.
