To Nancy and Shelly and the memory of my father, Sheldon, who has been a constant
source of inspiration throughout my life
Multidetector CT (MDCT) is much more than an incremental improve- ment over the previous technology. When compared with computed tomography (CT) imaging performed just 4 or 5 years ago, it is essen- tially a new modality. MDCT has significantly changed how I practice radiology and has reinvigorated my love for imaging. The images pro- duced are not only clinically diagnostic, but they have an aesthetic beauty that is both accessible and enticing to radiologists, clinicians, and even patients.
The purpose of writing this book is twofold. The first section brings together into one source all the practical information needed to suc- cessfully set up a MDCT practice, operate the scanners and 3D work- stations, manage workflow, and consistently produce high-quality diagnostic images.
The second section is a teaching file of volumetric cases. This is not intended to be a comprehensive collection of teaching material, but rather a showcase for the varied capabilities of current scanners and workstations. Each case is selected to demonstrate how the technology can improve the process of making a clinical diagnosis and then effec- tively relaying this information to other physicians in a format that is easy to understand.
I hope that readers of this book will not only get a better under- standing of MDCT and 3D workstations, but also a better appreciation of the art of radiology expressed by the images.

Preface
I owe a debt of gratitude to Chris Gordon and her team of excellent CT technologists at Long Beach Memorial Medical Center. Without their hard work, dedication, and friendship, this book would not have been possible. I want to acknowledge the invaluable contribution of Dr. John Renner, the director of radiology at Long Beach Memorial. It was his vision that enabled Long Beach Memorial to be one of the very first hospitals in the United States to own and operate a 16-detector multi- detector CT (MDCT). I also thank the administration at Long Beach, particularly Richard Decarlo and Terry Ashby for their support of this project. I am also indebted to my friends and collaborators from Toshiba America Medical Systems: Mike MacLeod, Bryan Westerman, Doug Ryan, and Jeff Hall, and from Vital Images, Vikas Narula. They have assisted and supported me over the years and have all con- tributed their expertise to this book in different ways. Finally, I would like to thank the following radiologists who contributed images or case discussions used in this book: Dr. Ruben Sebben, Dr. Hirofumi Anno, Dr. Albert de Roos, Dr. Stanley Laucks, Jr., and Dr. Alisa Watanabe.
