Ultra high frequency ultrasonography to distinguish ganglionic from aganglionic bowel wall in Hirschsprung disease: A first report

First study demonstrating 70 MHz ultra high frequency ultrasound can distinguish aganglionic from ganglionic bowel in Hirschsprung disease with 95% accuracy across 44 sites in 11 pediatric specimens. This novel imaging approach may offer faster intraoperative confirmation than frozen section biopsy, though in vivo validation is needed.
