It is with great pleasure and pride that the World Federation for Ultrasound in Medicine and Biology (WFUMB) publishes this “Manual of Diagnostic Ultrasound in Infectious and Tropical Diseases”. This is a book that will satisfy a great need that up to now has been unful?lled. Although there are many books that deal with various aspects of ultrasound, this is the only one that deals speci?cally with infectious and tropical diseases. It will provide much-needed knowledge and insight in these areas. It will be of especially great value in the teaching of health professionals in those parts of the world where ultrasound is just beginning to be incorporated into patient care. This book has had the good fortune to be conceived and edited by Drs. Lutz and Gharbi. They are excellent physician practitioners of ultrasound with much experience in teaching in the developing world. They have gathered together an outstanding array of chapter authors to create a most valuable book. All of the authors are to be congratulated on a job well done. I trust that readers of this book will bene?t from the material contained and will be enabled to provide better medical care to their patients. This is certainly a worthy aim, and one that WFUMB is constantly working to achieve. Marvin C. Ziskin, M.D.
