Multiparametric Ultrasound for Preoperative Assessment of Parotid Tumors: A Novel Diagnostic Pathway

Head &Neck, Volume 48, Issue 2, Page 392-406, February 2026.
ABSTRACT Background Accurate preoperative differentiation of parotid gland tumors (PGTs) is essential for facial nerve preservation. This study evaluates a novel, real‐time multiparametric ultrasound (mpUS) approach combining B‐mode, shear wave elastography (SWE), and contrast‐enhanced ultrasound (CEUS), based on qualitative image interpretation ...
