Example of a pleomorphic adenoma (PA) of the left parotid gland. (A–C) Parotid gland with tumor; (D–F) contralateral healthy parotid gland. (A) Ultrasound (US) image of the MSOT system; PA circled in blue. (B) MSOT image of 800 nm; Region of interest (ROI) circled in blue. (C) Hybrid US/MSOT image; ROI circled in blue. (D) US image of the MSOT system; ROI in normal (N) salivary gland tissue circled in blue. (E) MSOT image of 800 nm; ROI in normal tissue circled in blue. (F) Hybrid US/MSOT image; ROI in normal tissue circled in blue. (G) High-resolution image with normal US device. (H) Coronal magnetic resonance imaging (MRI) of the neck showing the tumor (arrow) in the parotid gland. (I) Intraoperative (OP) situs. The tumor is exposed in the parotid gland.
