Cardiovascular CT acquisition protocol optimization in pediatric patients, including newborns is often challenging. This might be due to non-cooperative patients, the complexity and variety of diseases and the need for stringent dose minimization. Motion artifacts caused by voluntary and involuntary motion are most frequently seen in cardiac imaging with high heart and respiratory rates. Dual source scanners of the second and third generation are particularly well suited to respond to these challenges. This can be accomplished with advanced scan options, such as high pitch scanning, short rotation times, automated tube voltage selection, tube current modulation and iterative reconstruction.
