Ultrafast shear-wave elastography for pediatric deep vein thrombosis: a prospective feasibility study.

Ultrafast shear-wave elastography was feasible in pediatric deep vein thrombosis, particularly in older patients and in those with occlusive deep vein thrombosis.

In exploratory longitudinal analyses, shear-wave velocity increased over time, supporting further investigation of ultrafast shear-wave elastography as a non-invasive quantitative biomarker of thrombus maturation in children.
