Abstract

One of the principal benefits of contemporary multidetector row computed tomography (MDCT) has been the ability to obtain high-quality data sets for evaluation of the cardiovascular system. The benefits of the greater number of detector rows and submillimeter image thicknesses were quickly recognized and are especially advantageous in children. For example, since imaging is performed so quickly, issues with motion are minimized. This is a substantial benefit of CTA compared with MR imaging, the traditional noninvasive cross sectional modality for pediatric cardiovascular imaging. This, together with faster and more powerful computers, including improved transfer and storage capabilities, offers improved depiction of the heart, great vessels, other vasculature, and adjacent intrathoracic structures in a fashion that is well accepted by clinical colleagues. In order to be successful, however, one must have an understanding of the technology and often unique technical considerations in infants and children. With this familiarity, excellent cardiovascular examinations can be performed even in the most challenging case.

Notes

  1. In order to convey the importance of technique, the critical technical considerations will be included for many of the following figures. For the sake of brevity, the technique will always be listed in the following sequence and units: IV contrast media amount (ml/kg), including any additional considerations; scan parameters consisting of tube current (mA), gantry cycle time (in s), number of detector rows and the thickness of each detector (e.g., 16×0.625 in mm), displayed image thickness (in mm) and interval (in mm).
