Acknowledgements
Above all, lowe a debt of gratitude to the late Professor van Ebbenhorst Tengbergen and to Dr. P. van Exter of the University Roentgen Clinic, Amsterdam for allowing me to train as a radiologist under their supervision. I well remember my initial surprise at being told that the function of their clinic was not to teach. Rather, it was to give one the opportunity to question accepted statements and to pursue one's own line of research.
It was a great honour and privilege to be able to visit the late Professor Johan Torgersen of the University Anatomical Institute in Oslo at that time. This afforded an opportunity to discuss his monumental work on the anatomy and movements of the stomach and duodenal bulb at first hand. With characteristic modesty he took pains to explain that his findings were merely an elaboration of the work of Gbsta Forssell and that he himself had added little that was new.
This study would not have been possible without the cooperation of Professor J.J. Heydenrych (Department of Pediatric Surgery), whose advice and assistance over many years is greatly valued.
I am deeply grateful to Heads of the Department of Radiology, Professor C.J.B. Muller, Professor J.A. Beyers and Professor A.T. Scher, for their continued support and for allowing me to devote much time to the project.
My thanks are due to Professor D.J.J. Bezuidenhout and Dr. P.J. van Eeden (Department of Gastroenterology), Professor D.F. du Toit, Professor L.C. Janse van Rensburg, Dr. E.L. Bouwer and Dr. H.D. Louwrens (Department of Surgery), Professor J.F. Klopper and Professor W.J .c.J. Rosenstrauch (Department of Internal Medicine), Professor D.J. Rossouw (Department of Anatomy), Professor J.J. van der Walt and Professor B.D. Middlecote (Department of Anatomical Pathology) and Dr. D.H. Jamieson (Department of Radiology) for their help with specific problems.
Dr. R.H. Hewlett (Department of Anatomical Pathology) and Dr. R.D.J. Jamieson (Department of Radiology) read individual chapters and suggested improvements; for this I thank them.
