Helical (Spiral) Computed Tomography

This practical handbook is an indispensable reference for radiologists who are converting from conventional computed tomography to helical (spiral) computed tomography. The book presents detailed, easy-to-follow, effective helical CT scanning protocols for all areas of the body and for three-dimensional imaging and explains the principles behind the recommended protocols.Chapters cover the head and neck; chest; abdomen and pelvis; musculoskeletal system; helical CT in pediatrics; and helical CT for three-dimensional imaging. Each chapter features a comprehensive list of protocols for specific clinical indications. The protocols are presented in an easily readable outline format that includes clinical indication; scanner settings; oral contrast agents; phase of respiration; slice thickness; pitch; helical exposure time; reconstruction interval; superior and inferior extent; intravenous contrast; and pertinent comments and pearls. Representative helical CT scans appear on interfacing pages with the protocols.
