I am deeply indebted to the many members of the Department of Radiology at Mayo Clinic who provided cases for the book. I have had many mentors and assistants who made this project possible. My training in radiology was highly influenced by distinguished radiologists, including Harley C. Carlson, David H. Stephens, Robert L. MacCarty, Reed P. Rice, William M. Thompson, and Igor Laufer. I am grateful to all of them. Grant Schmidt, the coauthor of the first edition, provided much assistance in making the first edition successful. Although he didn’t have time to coauthor this second edition, I am grateful to him for the many good ideas that he had for the initial textbook that remain part of this edition and for a long list of interesting cases that contributed to needed improvements for the book. My administrative assistant, Lisa Kay, was very helpful with printing, sorting, and organizing the revisions. The Section of Scientific Publications and Media Support Services at Mayo Clinic worked tirelessly to provide the product that I envisioned. I am grateful for the expert editorial assistance provided by the staff in Scientific Publications: LeAnn M. Stee (editor), Kenna Atherton (manager), Jane Craig (editorial assistant), and John Hedlund (copy editor/proofreader). The radiologic images were meticulously reviewed and prepared by Deborah Veerkamp, the drawings were originally created by David A. Factor, MS, and beautifully updated with color by Joanna King, MSMI, and the cover art was created by Jim Rownd.
As always in my career, my wife, Therese Johnson, has encouraged me and supported me in this effort. Always unselfish with her time and always willing to pick up the slack when I was not available at home, she continues to help me achieve when I would not have otherwise.
I hope readers find the book an efficient way to learn the myriad and fascinating ways of the gastrointestinal tract through imaging.
