Abstract
In addition to morphologic evaluation, cardiac computed tomography with a short scan time and a high spatial resolution may be performed to assess ventricular function in children with congenital heart disease, especially when cardiac magnetic resonance imaging is unavailable, inadequate, or contraindicated. Caution should be exercised over the computed tomography radiation dose because greater radiation doses are used to assess ventricular function than morphology. The three-dimensional threshold-based segmentation approach leads to higher accuracy and reproducibility of ventricular volumetry than the conventional approach, which frequently uses simplified contouring and two-dimensional disc summation. However, this approach is less frequently utilized in clinical practice than the conventional approach. Therefore, a step-by-step guide to cardiac computed tomography ventricular volumetry using three-dimensional threshold-based segmentation is presented for congenital heart disease.
期刊介绍：
Official Journal of the European Society of Pediatric Radiology, the Society for Pediatric Radiology and the Asian and Oceanic Society for Pediatric Radiology
Pediatric Radiology informs its readers of new findings and progress in all areas of pediatric imaging and in related fields. This is achieved by a blend of original papers, complemented by reviews that set out the present state of knowledge in a particular area of the specialty or summarize specific topics in which discussion has led to clear conclusions. Advances in technology, methodology, apparatus and auxiliary equipment are presented, and modifications of standard techniques are described.
Manuscripts submitted for publication must contain a statement to the effect that all human studies have been reviewed by the appropriate ethics committee and have therefore been performed in accordance with the ethical standards laid down in an appropriate version of the 1964 Declaration of Helsinki. It should also be stated clearly in the text that all persons gave their informed consent prior to their inclusion in the study. Details that might disclose the identity of the subjects under study should be omitted.
