We analyze the potential use of ultrasound in the study of the thorax in children. The physical limitations imposed on sonography by the ventilated lung and thoracic cage are well known. ⋯ These specialists take information from physical acoustic phenomena that is not directly convertible into images of the human body, starting with the interpretation and handling of artifacts. We give a critical assessment from a radiologic viewpoint that is both necessary and important.

Comparative StudyClinically useful dilution factors for iodine and gadolinium contrast material: an animal model of pediatric digital subtraction angiography using state-of-the-art flat-panel detectors.
Iodinated and gadolinium contrast agents pose some risk for certain pediatric patients, including allergic-like reactions, contrast-induced nephropathy (CIN) and nephrogenic systemic fibrosis (NSF). Digital flat-panel detectors enhance image quality during angiography and might allow use of more dilute contrast material to decrease risk of complications that might be dose-dependent, such as CIN and NSF. ⋯ Knowledge of the relationship between image quality and contrast material dilution might allow a decrease in overall contrast load while maintaining appropriate image quality when using digital flat-panel detectors.
