Abstract

This report demonstrates the feasibility and safety of using contrast-enhanced ultrasound (CEUS) to confirm intranodal needle position in children requiring dynamic contrast-enhanced magnetic resonance lymphangiography (DCMRL). A total of 7 patients were evaluated using CEUS after nodal puncture on a detachable magenetic resonance table, with 2 nodes cannulated in each patient, resulting in a combined evaluation of 14 nodes. The nodal cannulation success rate using CEUS was 85.7% (12/14 nodes). DCMRL was performed successfully in all patients with good contrast opacification of the central conducting lymphatics. Out of the 14 nodes, 2 nodes in the same patient demonstrated persistent extravasation on CEUS despite needle readjustment, requiring conversion to fluoroscopic lymphangiography. No adverse event related to the injection technique or CEUS was reported.
