Dr. Kiesslich secured authors who are at the top of their field in GI Imaging to write articles that will serve as an up-to-date source for all gastroenterologists. The issue is divided into sections devoted to imaging of the esophagus, stomach, small bowel, liver& pancreas, and colon; two articles are devoted to molecular imaging. Readers will be very interested in the articles devoted to Contrast Enhanced and 3D-Endosonography, High Definition and Filter Aided Colonoscopy, and Autofluorescence and NBI Imaging in Barrett's Esophagus.
