Virtual endoscopy is a valuable independent diagnostic tool of increasing importance. This book provides an in-depth evaluation of the technical aspects of virtual endoscopy, and detailed information on indications, implementation, and interpretation in a clinical setting. It is designed to support radiologists and educators in approaching this rapidly developing field. It will also assist consumers in judging the applicability of software and hardware packages for virtual endoscopy, and will benefit producers by highlighting current limitations and potential improvements from a clinical viewpoint.1997). Time-of-flight MRA is primarily used to assess fast, unidirectional flow phenomena. ... If the velocity encoding of the MRI sequence used does not match actual flow, reduced or turbulent flow signals will occur. As in TOF-MRA, long image acquisition times and the occurrence of background motion artifacts are drawbacks of this technique. ... The contrast agents used in CE-MRA are gadolinium compounds, which have an extracellular, but no strictly intravascular, distribution. Thusanbsp;...
