Full Description
This book provides an in-depth look at the potential of modern computerized contrast delivery systems. The characteristics of bolus injection techniques are described and illustrated with comparative CT scans, accompanied by a review of the literature. The book also offers a detailed analysis of MDCT protocols for various anatomical regions. Clear explanations of each phase of contrast enhancement, along with tables summarizing the main MDCT protocols in use today, allow the reader to select easily an optimal protocol for the investigation of different target organs.
