Parameters quantified using CEH-EUS measurements concerning leiomyoma, low-grade malignancies of GISTs, and high-grade malignancies of GISTs. (A) PE, (B) WiR, (C) WiPI, and (D) WiWoAUC (p<0.001 at PE, p=0.009 at WiR, p<0.001 at WiPI, and p<0.001 at WiWoAUC between the leiomyoma and high-grade malignancy GIST groups).

CEH-EUS, contrast-enhanced harmonic endoscopic ultrasonography; GIST, gastrointestinal stromal tumor; PE, peak enhancement; a.u., arbitrary units; WiR, wash-in rate; WiPI, wash-in perfusion index; WiWoAUC, wash-in/wash-out area under the curve.
