Ultrasonography (US) is an operator depended image modality that is difficult to reproduce and interpret by others. Competence of the US operator is crucial for reliable diagnostics but no evidence-based certification of head and neck US skills has been developed. Investigators conducted an experimental study aimed to explore diagnostic accuracy and establish validity evidence for certification standards in surgeon-performed ultrasonography.
