Multidetector CT (MDCT) is much more than an incremental impro- ment over the previous technology. When compared with computed tomography (CT) imaging performed just 4 or 5 years ago, it is ess- tially a new modality. MDCT has signi?cantly changed how I practice radiology and has reinvigorated my love for imaging. The images p- 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 ?rst section brings together into one source all the practical information needed to s- cessfully set up a MDCT practice, operate the scanners and 3D wo- stations, manage work?ow, and consistently produce high-quality diagnostic images. The second section is a teaching ?le 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 eff- 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 und- standing of MDCT and 3D workstations, but also a better appreciation of the art of radiology expressed by the images.
