Preface to the third edition

Almost 20 years have passed since the first edition of Anatomy in Diagnostic Imaging was published, and encouraged by the receipt of the second edition we felt it was time to prepare this third edition, maintaining the scope of the previous editions, as an all-round reference collection of fully interpreted normal images, addressing students as well as professional medical personnel working with diagnostic imaging.

We have made a special effort to elaborate on MR imaging of the major joints, shoulder, elbow, hip, knee and ankle imaged in two or three planes. A CT series of the skull has been added and the CT series of the brain has been replaced by a new series. The section on obstetric ultrasonography has been considerably expanded to cover all standard examinations performed during a normal pregnancy. Further, we have added an MR series of the orbit and a new series of the lumbar spine, and other images have been supplemented or replaced.

The introductory chapter has been revised and updated, still with the scope that it should be nothing more than an understandable introduction to the imaging techniques and principles presented in the book.

Acknowledgements

During the preparation of the third edition we have again profited from the generous help of many colleagues: Connie Jørgensen, Rigshospitalet, Copenhagen; Anne-Mette Leffers, Hamlet Private Hospital, Copenhagen; Peter Oturai, Rigshospitalet, Copenhagen; Henrik Lundell, Hvidovre Hospital, Copenhagen and Martin Vinten, Glostrup Hospital, Copenhagen, together with colleagues and staff at the X-ray Department of Gentofte Hospital, and our thanks also go to photographer Keld Ottosen, Department of Cellular and Molecular Medicine, University of Copenhagen for skillful help with the photographic plates.

We also wish to thank Wiley Blackwell for their excellent collaboration and patience during the preparation of this third edition.

Finally, we cannot sink deeper into the bottomless debt of gratitude to our families for allowing us again to spend countless, but exciting hours preparing this third edition.

Principles and Techniques in Diagnostic Imaging

Several physical principles are utilized in diagnostic imaging to visualize the structure, composition and functions of the living body. An elementary understanding of the imaging techniques and the basic physical principles is a prerequisite for full recognition of the diagnostic possibilities and for thorough and critical image interpretation.

This chapter is an introduction to the basic physical principles, the techniques and the concepts used in diagnostic imaging, avoiding undue technical details and strenuous mathematical formalisms.
