Although usually CT or MRI scans are necessary for correct estimation of the tumor size and for planning of surgery, the importance of ultrasound in such diseases is that it allows a rapid diagnosis, even if the tumor cannot be seen in the clinical examination. Furthermore, ultrasound of

Though most applications in the head and neck remain off-label, many studies report an improvement of diagnostic accuracy by using CEUS in the head and neck, and there appear to be a variety of
