MDCT in children: Scan techniques and contrast issues


Journal Article (Chapter)

Computed tomography (CT) is an essential imaging modality in the evaluation of infants and children [1]. Technical advances, especially with multidetector-array CT (MDCT) have provided increased opportunities for established uses as well as for new applications, such as evaluation of possible appendicitis, renal colic, and cardiovascular abnormalities. However, these technical advances are often complex and can be confusing. This complexity arises from the equipment, with increasing numbers of channels or arrays, and from the scan technique, consisting of multiple options for scan settings and intravenous (IV) contrast medium administration. Only with a solid understanding of these technical considerations will diagnostic MDCT in children be optimized. Therefore, this chapter focuses on the technical aspects of MDCT rather than on its applications. In addition to this technical discussion, issues in patient safety related to MDCT are addressed, including radiation management as a fundamental responsibility of the radiologist and radiology personnel [2]. © 2008 Springer-Verlag Milan.
